Help needed to troubleshoot electrical on dakota
For all dakota pros,
I needed to replace the ABS module on my dodge dakota, so in doing so I pulled off the fuse box and all the connectors in order to remove the battery tray. Note: the Dakota worked perfectly before hand. When I put it all together the electrical system went haywire. I started it up and took it on a test drive. When I pulled it out everything seemed to work perfectly. Then upon pulling it in the shop all the warning lights on the dash illuminated. I turned it off and placed the vehicle in the run position. The ABS, P-Brake, oil pressure and engine check light remained on, the wipers worked, but only at low speed and they seemed to be losing power. As well the left and right turning signals worked fine as well. I then started the vehicle.
When I started the vehicle the same lights remained on. The second I hit the multifunction switch, it acted as a kill switch to all electrical components. The remainer of the dash lights illuminated, the high beams came on, the shift linkage would not shift and you could hear the transfer engaging in 4LO and all wheel drive. Now the wipers would not work, turning the wipers on would turn on the left driving light. The headlights wouldn't work either. As well the turning signals would no longer work. And all the gauges on the dash dropped to zero; RPM, speedometer, temp to "C", and fuel to "E".
-I cleaned all connectors, ensuring there was no arch.
-I reattached the old ECM onto the new ABS module.
-Resting the ECM and clearing the codes would only bring them back.
-All ground were accounted for and are secure.
So if anyone has ideas please feel free to let me know.

I would pull every fuse and check them. Also i would grab a diagram of all the relays and do a continuity test on all of them. If your eyes are bad you can do a continuity test on the fuses also.
If you don't know how to do a continuity test simple grab a eleltrical meter that has a continuity test (the setting that makes a BEEP) when you touch the two leads together. Simple touch the leads on each side of the fuse or matching pins on the relay and listen for a beep. Beep = good, No beep= bad.

Thanks for the info, and no worries I know, I checked all the fuses. I'm a mechanic myself, only 4 ASE's though. Just wanted to get some ideas. All and all, I think it just might be the fuse box itself. See, electrical isn't my best, but with enough troubleshooting I'll nab it. Still open for ideas though.
