3.8L fuse/fusible link location

[inthedirtagain]

Stuck at work and don't have my manual with me, so advice is appreciated.

Picked up 1981 Sun Runner with the 3.8L GM last fall. Got it home and ran it on the muffs, then winterized and stored in my shop. Yesterday, I was about to listen to the radio while replacing all the fluids, but I have no electrical at all right now. No lights, no crank, no gauges. Battery tested at 12.57 and is currently on the charger. Previous owner did a hack job on the wiring for the stereo install, but was functional. I'm gutting the interior and doing a complete redesign of seating, but really tore things down to access all wiring running from stern to helm. I've downloaded the electrical troubleshooting sticky already and will follow those directions once I get home. But first........can anyone tell me if/where I could find a main fuse or fusible link on this thing? My plan is to check it and eventually replace with a circuit breaker of the appropriate size.

guessing the 229 Chev in front of a stringer

look for the big fuse on the starter motor. its a 50 or 60 amp if I remember

did you clean the battery terminals?

Here is an iboats posted image from the archives for the 2.5/3.0, however wiring is similar for your V6

Terminals were pretty clean with no evidence of normal battery corrosion. However, I do plan to clean them up and liberally coat them with dielectric grease. I'll take a look for a fuse near the starter when I head home.

Use marine elecrical varnish vs dielectric grease
