This is on my 2006 Mainship 34T it goes from the battery charger to the generator battery. Appears to be some kind of fuse?

Greetings,
Mr. R. Sorta looks like the remains of a switch of some sort with the little nubs but the twisted wires don't make sense. Have you put a VOM across the 2 ends?
 
Looks like they twisted some wires together and then crimped on connectors. Have you tracked the wires and see where they go?
 
Yes, Those buttons look like something from a switch alright., probably a cutout of some sort.
 
My 2008 34HT had 4 battys (thruster, house/start 1, house/start 2, plus Gen start) connected to a 3 bank charger by adding a diode isolator. I'm wondering something similar was originally installed on yours and maybe the PO substituted a switch to charge gen start only when chosen manually?

I modified my set up to use the 3 bank charger to charge thruster (now also serves eng start) and house 1&2. Gen has its own Gen and normally takes care of itself when run periodically. I also changed my Gen batty on/off to a off- 1-2-all sw with same foot print & mounting, and use the 2nd position as a jumper to my house batty. That allows periodic charging or emergency Gen start w flip of manual switch.

Thanks. Looks like I have similar setup. I removed the wire to the gen battery and will probably do same as you for emergency gen start

The switch replacement & jumper is a pretty b easy retrofit... worth doing as insurance and peace of mind
