so my buddy and i need to repair this church van for a pastor we know, but we're not entirely sure what's wrong with it. here's the deal. 1st problem: it's a dodge. ok. so we thought the alternator was bad, pulled it, had it checked, it was fine. then we replaced the battery because it wouldn't hold a charge. then the van decided one day to sputter to a stop, die, and not restart. now the battery is dead. the check engine light codes are as follows: 37 Shift indicator light failure, 5-speed OR part throttle lock/unlock solenoid driver circuit (87-89) OR solenoid coil circuit (85-89 Turbo I-IV) OR Trans temperature sensor voltage low (1995 and on; see NOTE 2) 41* Alternator field control circuit open or shorted the van is a 1990 with an auto tranny. so the 37 code doesn't make much sense to me. code 41 sounds like a hit, but i don't know what that is or how to check/repair it. any ideas? in terms of the motor dying - is there any chance that this could be related to the catalytic converter backing up? i guess a couple weeks ago my buddy saw that it turned the dreaded red hot. is it fried for good now? is that something that the average home mechanic can replace? i appreciate any help you can offer!!! colby stephens. www.web.pdx.edu/colbys - check out the story of the build of my k5!
