I have a 2000 Chrysler Grand Voyager SE. Recently I had a battery terminal break while running and the cable likely bounced on and off battery post a couple times. I am sure this caused lots of problems as it went back and forth from just alternator output to alternator and battery, as well as crazy grounding issues.
The van shut off and I was able to reconnect the cable and restart, but all lights (corner and signal bulbs) were blown as well as headlight (low beam only, as highs were not on at the time) A replacement of all the bulbs fixed that, but now I have a couple other problems.
The overhead trip computer does not come on now and I am not sure if the radiator fans work. Though the van is not overheating, I have not noticed at all that the fans come on. Is there a way to force them? I want to verify PCM function as well as relay. I did test the fans themselves by directly wiring. How does one verify the solid state relay? Any suggestions on the overhead computer? Likely related, or just both blown at same time? Are there any common fuses or relays? None of the relays and fuses, etc, are labeled under dash.
Thanks for any help.

EDIT: Update- I read from a Haynes (still on the shelf at parts store) that there is a resistance range on the temp sensor that can be read to verify. I disconnected the connector to read it and connected DMM. It reads 3.5 k and does go up as the car heats up, and more importantly, the fans come on when not connected. This means that the system does work and either the van hasn't gotten hot enough or the sensor is just out of tolerance. Either way reassuring, as the van isn't overheating and is running in middle of temp gauge range.
So now to figure out about that overhead trip computer. Any ideas where to look for applicable fuses, etc? Thanks.
