'89 Dodge keeps blowing modules

will270win

The varmint express owned by my good friend and worlds coolest gunsmith has gotten sick and keeps blowing modules. He replaced the fuel pump cause the pressure was to low pressure and this module problem is the only remaining issue. If it helps, this is the 89 Ram 4X4 with a 318. We don't get much varmint hunting in with this joker broke so please lend me your expertise.

Ah yes, the old Dodge. I've had my share of em. Now Dodge's are notorious for electrical problems. I would check the steering column for any wire fractures. Wires may look good but be very brittle and not making connections or shorted out. Get the tester out and start checking circuits. Sounds like a dead short.

Or check the local auto parts stores for a rebuilt pre 1969 points distributor, used to get them for $39, but that was 30yrs ago..

Contrary to popular opinion, shorts don't often cause anything other than blown fuses and opens don't do much other than to cause something not to work. And the trusty Dodge is no more prone to electrical problems than any other as GM (I believe) made the wiring harness' for every domestic maker.

Now...

1. Always check for a faulty ground on the chassis and engine.

2. Have the alternator checked for AC riding on the positive line. My guess is that your system is more AC than DC because of a diode failure, and that's the worst news in the world for some electronics.

3. Check for corrosion. Over time salt will cause problems, but that's why we have fuses.

My bet is alternator.

Almost forgot - Voltage regulator (usually mounted on the firewall). Most often corroded with a poor ground reference.

We will check it out. Does this model have a ballast resistor? Maybe that's it as well.
