Fuse/bulb in charging system 85 s10 Blazer - 10/4/2007 12:55:19 PM    Billy_225   Posts: 2 Joined: 10/4/2007 Status: offline Anyone know of any bulbs in the warning light system that would put the alternator in 'no-charge' ?? And where's the fuse that would do the same thing? I'm assuming in the main distribution box. Post #: 1

I've got the appearance of an alternator failing but it might be something less.  I went to get an alternator. looked the replacement up online and it came with this intstallation alert... INSTALLATION ALERT! A blown fuse or bulb in the warning lamp circuit may cause a "no charge" condition. I'm just looking for this fuse or this 'possible' bulb.  There may be a bulb in series with a relay somewhere, or there may be a fused relay, or just a big fuse that would keep the alt from charging the battery.

The problem went away when you changed the switch, what happened when the switch was merly unplugged?  _____________________________ 84 Chevy C20 Built 350 (in reply to GUS) Post #: 6
