I'm having an electrical problem that has me stumped. Truck is a 1997 CMC Sierra 1500. The (newer DieHard) battery was drained dead in a day or two. Troubleshooting, I found the culprit to be the #19 "Radio-Batt" fuse, that cuircut was drawing .9 amps. with everything turned off, (lights etc.) I'm trying to find out what else is on that circuit before tearing the dash apart etc. If anyone has a scan or photo. of that portion of the wiring diagram I'd be most appreciative!

 

Get a Haynes manual...I find it to be invaluable

 

don't think it has the same wiring diagrams as the factory shop manual.I'll have to see if I can find an unwrapped one.
