Electro-Gubbins: Anyone know what this is?

Was diagnosing a dead battery when I came across this crusted up Frankenstein connection.

The bus is a 2005 GMC Savana 3500, 6.0 gas, Corbeil. I was told this is not a GMC-specific part. It's located right above the truck battery under the hood. That thick cable on the right goes to the positive side of the battery (which is a horrendous side-poster), and the right side lugs are connected with a copper plate. The left side lugs go somewhere into The Abyss.

Chasing the dead battery, I cleaned all of these connections and was, of course, tightening the last nut on the top left when it broke the casing. I learned these are 12V circuit breakers, and this one is a 15 amp, based on the little copper plate inside (there are ZERO identifying markers on the outside casing).

I'm also in the middle of bleeding the braking system after a hard line replacement, but not sure if it's a good idea to start this thing without that breaker connected.

Any ideas?

Thanks

Those are standard auto reset circuit breakers. They are mounted into a gang configuration. Any parts store should have them. They are sold by the item. The gang you have was done by the coach builder.

Thanks!



I called around to the local parts stores and they all had them, just not the right amperage. I did find one online though. I was concerned with starting it without that in place for the brake work, but the scanner and the breaker are coming same day, so it all worked out.


Thanks for responding!
