Generator light issue - HELP! - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Ok, I was a dummy and hooked the battery tender up backwards and it sat like that for 3-4 days. When I noticed it it fired right up but the generator light came on.

Took it and had the battery tested. Tested fine.

Changed the external voltage regulator.

Light was still on.

Took off the alternator had it checked. Checked fine but changed it out anyway cause the bearing felt kinda rough.

Light is still on!

Any help or next step suggestions would be awesome.

Is there a fuse or anything else it could be?

Ok I figured it out and figured I'd post what I found.

The fusible link was burnt. Replaced it. For those unaware of it. It is the small 16 gauge wire going from the battery to the junction box located on the passenger fender.

I also found the cluster fuse blown inside the cab. 3 amp fuse. Replaced it.

Those 2 items fixed the issue.
