can these two issues be related? my WTS light flashes very evenly-not a bad connection-very patterned. my mechanical voltage gauge shows me the alt is not charging. my grid heaters are NOT hooked up, so i am not seeing any kind of large drain from them. it did this last weekend, but i shut it off and restarted it-all was well. today, it is doing it again, and several restarts have not made it go away. today was the first time i used the truck since the last time it happened.

temps are in the 20s, truck is kept in an unheated shop, has no trouble starting.

any ideas?

 

Yes, that is a common symptom of a bad PCM. Sorry.

 

no, dont be sorry. i like to get rid of ecms.

since my truck is now a 5spd, i dont have a/c, i dont have cruise, i dont have grid heaters, and if i run an external voltage regulator, i really have no need for the ecm; correct?

i did a ecm/factory wiring harness delete on another '92, but ended up having trouble with things like headlights/blinkers, and windshield wipers.

so really, all i need to do is get an ext regulator, and i'll be ok w/out ecm input

 

True.

 

thank you for your insight.....time to go steal stuff from my parts truck
