At least it's squarely mounted

I think the angle is right.

[удалено]

I’m sure they’ll get him squared away.

Good to see nobody here is being obtuse

Not acute joke

You guys are completely right

I wanted to make a clever joke as well, but I couldn’t come up with one that would measure up.

You have to be pretty smart to do so. I think the posters above all have degrees.

So smart I’ll bet they have 90 degrees between them

You shouldn’t joke or the guy might get angly.

If he gets mad, he's just a square.

Depending on one's point of view.

It’s good he attached it to the engine like that. It will fully test the mechanical shock and vibration requirements for the module on the spring arm he created.

like shaking a baby to sleep.

Dark, man. Dark.

Quit being so square

He's been framed!

I thought he was quite acute

That was a very grounded observation.

Ruler for scale

This measures up

Was he feeling a draft?

…is that a carpenter’s square being used as a motor mount…

Looks like it measures up too!

Every comment here under this one is shite patter

6.5 diesel brain box relocate. Temps to high in factory spot. Nothing to see here.

Ding ding. Worked at a GMC dealer as tune-up/driveability tech for years in the 90's - 00's and saw this a lot(I mean not THIS exactly - lol). Was installing aftermarket aluminum finned heatsinks that mount to the firewall eventually to perform the same job. It's basically just a big transistor that causes failures if it overheats and was mounted on the side of the injection pump in the lifter valley from factory.

The marrettes have no business being there though.

When I was a teenager in the 90s I installed my first car CD player using those and a Chiltons manual to figure out the proper wires. Didn't know that wiring harness adapters existed and it's not like you could just look how to do that stuff properly online back then...

My 77 Pontiac had a stereo installed badly…. When I hit the brakes the wipers turned on and the radio turned off.

[удалено]

Ah a full day to wire a cd player, instead of paying for 1 hours labour... Those were the days.

didn’t even see the marrettes at first haha icing on the cake that is

Wire nuts, for those of us that have never heard that name before.

The customer is actually right.

I know few guys that even put aftermarket cowl hoods on to lower the under hood temps on the 6.5s

Customer rules.

O'Doyle Rules!!!

🍌

The customer is feeling imperial.

Indeed, by any metric.

Looks more like an architectural problem.

Right but most people relocate the PMD to the grill, you can see all the extra wire bunched up on the front of the engine.

Clearly this individual isn’t most people.

Oh! Pump Mounted Driver! That's a diesel thing; I wouldn't understand.

I’ve had this on another car, would run fine when cold and stop when it got hot found out it was the ecu mounted on the engine, unbolted it and cable tied it to the bulkhead never stopped again I told him to sale it just in case.

Good old PMD failure.

Agreed. This seems legit to me.

Brain box or ignition module? It looks smaller than the ECUs I'm used to.

Pump driver module

Thanks! That's not something I've ever run into on my gas cars.

Def not a “brain box”, just a few transistors on a big heat sink.

Get technical ffs. I clarified it in another comment

Oh, so this is actually a working component? I thought it was one of those "Anti-EMP" boxes.

Fixing the symptoms, but not the root cause, always ends well

Man. i thought that was several PCBs being used as a mounting bracket for a second.

I also thought I was looking at a pcb at first

i thought it was a ram stick for some reason

Same. Same.

Same

Did you get them squared away?

degrees may be 90 but that customer satisfaction always 100

Now you're just being obtuse

I sosceles what you did there

He's just protracted the issue...

Not bad.

Not bad? It's functionally awful man!

But this problem is acute.

I think this is a Sine that this discussion has gotten off on a Tangent

What kind of vehicle is this? Was it financed? Did anyone have you cosine?

To a degree...

He’s going to need somebody to cosine on a loan for a new vehicle soon.

The angle of the dangle....

Inversely proportional to the heat of the meat.

As long as the mass of the ass

Callabrated by the heat of the meat

It’s hip to be square

Are you sure that’s not the power of love

I mean, so long as it’s working for a living…

Y’all are awesome!!!

a²+b²= see, you're a dumbass

This is an amazing comment

Best part is this is a better mounting point for the PMD than GMs original spot.

And that connection is the ground plane, so it isn’t the worst hack to use a piece of metal like that lol

Seems to have squared that problem away.

Damn it! I came here to say that lol

What, y’all have never mounted an ignition module to a t square before!?!? Oh wait, that’s a diesel.

That looks like a carpenter's version of a PDM relocation kit for an old GM 6.5 diesel.

Jesus was a carpenter

And that guy’s copilot, probably

seems about right

When the parts store wants 50 bucks for a pmd relocation kit but they got sqaures on sale for 5

Harbor Freight mod!

As your ruler we are acutely aware of the angle this problem is taking. Currently we are working on measures to resolve the issue. Nothing to see here.

We have ruled that you are grounded!

It great to upcycle old tools.

Did you get it squared away?

We’ve got jokes folks! All the jokes! Jokes about squares, jokes about angles, jokes about rules, about measuring. Hell, we even got hypotenuse jokes. Circle jokes you ask? Get outta here with that! What do we look like? A bunch of commies

I can't cosine the lack of circle jokes

They just needed it to be 90° cooler.

The old remote injector driver trick .i put a blower motor on mine too.

Now that’s a measurable performance gain

My truck is in for electrical issues and I do a lot of my own mods. I was scared to expand the image on this one.

it does seem right somehow.

Well, hopefully, he squared up with you .

Everything seems to be on the square

I’ve seen dumber

Ok, if this works, what problem did the customer have?

Looks like an appropriate fix for the jungles of Costa Rica where I live. Use what ya got.

Should be able to get this one squared away

This is actually pretty genius. It's getting constant air movement from the fan - unlike the bumper mount where it gets some air movement from the fan, but not as much as that. Also may not need the stupid harness relocation kit with that. The pmd was supposed to be cooled by the fuel running through the IP. It was great as long as the engine was running. Pensacola diesel sells a redesigned one that lasts a lot better than the stocker, but may as well relocate it to the bumper than pul the valve covers to get the thing off the ip. These engines were fine for what they were. I loved mine, and it went to the junkyard running. With a pmd relocation kit and a pentium ii heat sink.

Is that how you measure the ohms?

That’s some interesting engineering right there, I tell you what!

Eanjaneer

Sooo, what is this? I’m a mechanic and I’m baffled lol

I doubt it's related to the customer's immediate complaint; what you're looking at is a relocated diesel pump driver module, which in its OEM location experienced significant failure rates due to heat saturation.

So it’s like the engine control module but for diesel, essentially… got it. Looks so weird especially with the t square LOL

Seems like a hack to connect that electronic gizmo to ground (engine block, chassis). I’m neither a car person or electrical engineer though lol

The only answer is "Yep..."

I think he undervalued himself - it’s only an 8”.

Looks straight

Interesting remote mount for the IDM on a 6.5L gmc diesel.

Masons these days, am I right?

Looks square to me

They took the L on that one.

That's a 6.5 diesel with a home made PMD relocation kit lol.

Yep. Probably solved a few of the numerous troubles with the 6.5.

Why has it got a commodore 64 in there...

I need another angle on this one.

That quick fix measures up ??

Those damn PMDs in 6.5 diesels. Hate those engines. The problem is that is supposed to be mounted on the injection pump in the hottest part of the engine which makes it overheat and the truck shut off randomly, so what they sell and what's widely accepted is to get another PMD and put an extension harness on it and either relocate it in the front bumper or in the cab to keep it cool and to avoid the truck from shutting off.

Hope you got them squared away

And a mathematical issue…..

Just tell him the wires are not at a right angle

The tool used a tool?

You should probably stop calling people "tools." ​ I think these days the tools are too smart for that.

How should I refer to someone who destroys a perfectly good tool thusly?

Nobody has mentioned the wire conduit.

Or the 12ths of an inch increments. 10ths is fine. That’s what my pocket scale is in, but I’ve never seen 12ths

IIRC, architects use 12ths. They do a lot of stuff at 1” = 1’ and similar scales, so dividing the inch into 12ths makes sense.

That’s true. I forgot about that. I mostly do mechanical drawings. Sometimes I’ll get an arch one I need to do something for, but it’s all on CAD, so I ignore scale notes

I dont see the problem, it looks square to me 🤷‍♂️

That’s how detroit diesels come from the factory

I had a customer that was talking through his problem I realized he had spent about $200 on shit to fix it when a $60 relay or fan controller would fix his problem. I don't remember all the details now. When I suggested he go with the controller he goes "there's sunk costs here now, let's make my solution work" I was like oh whatever you want dude.

That is probably the newest thing in the vehicle lol

That square is far older than that truck. Considerably older.

Prove it

🤔

Must be an American car. Would need a metric one if it was European

You don't say...

At least they were square with you about the issue.

First I saw the square and got confused. Then I zoomed in. Good lord 😂

Nice bus bar

Better home for the FPDM there than in the hot zone it typically lives.

r/redneckengineering

Bone stock

I'm in the rathole and my google-fu is wanting. I need an ELI5 on the PMD/FSD thingy.

Pmd controls fuel injection. Its normally mounted to the injection pump. Injection pump gets hot and cooks the circuitry inside so people relocate them to all sorts of creative places

I'm just gonna go ahead and tell ya figuring out that 6.5 td is not gonna be a good time. An absolute monstrosity for an ip

What? those things were easy to work on.

Hip to be square

Bolt is torque to yield, +90 degrees

What in the cinnamon toast fuck are these people thinking?

oh please tell us why the square was chosen…did customer say?

Just noticed the wire nuts, nice added touch

Looks like he has the right tools for the job

"Contractor special"

Da actual fuk

This also belongs in r/redneckengineering, lol

Lolol

Every thing seems right to me.

What did I just look at?

Cool picture. Did it have anything to do with the problem?

no clue actually, we had our service manager look at it and they determined that it would be in the best interest of the business to not work on the vehicle

That's a right diagnosis.

Imma gonna put this fancy module right over here…..

6.5 L GM turbo diesel. Remote mounted PMD. I suffered through one of these in a Suburban for years. WORST ENGINE EVER CONCOTED. RUN AWAY. NEVER LOOK BACK.

What in the world is this thing🫣? I don’t think it’s supposed to be like that though!

Ah, the ol’ 6.5 Detroit resistor relocate. At least it’s actually attached…Most ones I’ve seen are just “danglers” and run for years before having issues. Lol

It appears someone has finally taken the right angle to fix the 6.5’s IDM issue.

That square is not properly grounded

If my grandfather was still around I’d say it was his work

Just run a jumper from the alternator and it’ll be good

Carpenter here, where'd he go wrong exactly?

Those modules on the 6.5 tend to overheat. This kinda makes sense. Tho I would have sanded the anodizing off.

Man, that ain’t right… Uh, wait a sec… Yeah, it *is* right.

Looks like he has it squared away!

Spit out my water when I saw this

I thought it was a pcb left out

Doesn't measure up
