I bought my aurora wrecked, bags popped. Im about start driving it. I have a charging system problem. I check the alternator and it was good. I have a code of p1637, gen. L-term circuit?? Anyone??

'cant help ya with the code but your avatar is kool

Dont All Jump On Itttt

This comes from Book2 of the service manual(1997): DTC P1637 and a low battery charge may be caused by a generator fault. Such as a shorted output diode, malfunctioning regulator, open or shorted rotor, or open sense lead. Refer to engine electrical for further information and generator diagnosis. This DTC will not set if circuit 225 is shorted to voltage but may cause a parasitic load on the battery with the key off. I hope this help. A mechanic may be able to interpet this stuff.

Thanks for the reply, I think the battery is up and charged. I did test the alternator. I think the problem lies in the wiring to it. Im going to work on it soon

Thanks

For all of theose who cared or acted like they did I figured out the problem. theres a small wiring connector in the battery tray that had burned
