2005 Dodge 1500 Electrical help

The problem.

No parts at local yards. Had to order. Should be in tomorrow or friday

If it's just that one bubbled-up area that is the problem, I'd re-build the electrical connection with soldered-in heavy wire jumpers. Unless there was corrosion present, that may have been a weak solder connection or an undersized pcb trace.

Up here, that would be a pre-paid item, so you probably own the new one already though.

Have a 04 dodge truck, Sometimes it will not turn over. Lights, radio work but it will not crank. Sometimes if I slam the door really hard, it starts right up. Sometimes I have to raise the hood and shake the fuse box and it finally will start. Any ideas? Thanks in advance

Probably the same thing to poster of this thread fixed. The thingy under the fuse box, what ever that's called.

Unless you have a multimeter and know how to use it....best you gan do is guess. Which isn't the road I'd take with the cost of some of these parts.

I am guessing you have a loose/corroded connection somewhere, and slamming the door and jarring things around sometimes makes it work.

The issue with the circuit board that I had, isn't something that is gonna magically work by shaking it.

That can sometimes work on a two sided board, but if there are circuits inside the layers as well (I work on computer boards with as many as 8 signal layers as well as ground planes and power planes) it could be evidence an internal layer overheated and bubbled to the surface. Designers like to put the ground and power planes on the inside layers to help reduce signal crosstalk.

Another thing that happens is that road salt+water can short traces (looks like there are mineral deposits on the board, maybe?) and you can even have the tin "lead free" solder dissolve the copper in the circuit traces and exude crystals called whiskers that then bridge gaps to make shorts.

If he has gotten another board and it is working, I think that is a far better option than trying to resurrect the old one.

Everything is fixed now.

A boneyard entire fuse box was $200. Not worth trying to learn circuit board repair

Nice that you didn't have to go to the dealer. :thumbsup:

Agreed,

The cargo light on my '07 2500 has never worked (bought it used with 68k on it), traced it to the ipm but was always to cheap to replace it. It isn't my favorite system but not the worst either.
Now I have a cap on the truck so I don't even care.
Glad you got yours fixed.
