I thought I would post a solution to a problem with a C80 restarting on its own, the radar doing the same. It has done that since I got the boat a few years ago. I replaced the port (and house) battery bank with 2x6v golf cart batteries with lots of amp hour capacity, but not so much cranking amps. After I did that, when I restarted the port engine the C80 almost always shut down on the power voltage drop. Nuisance but no big deal.
Several years ago I had replaced the wiring to the C80 power feed on the switch panel with 10 gauge wire before, but it did not solve the issue, so I wrote it off to a problem with the C80's power needs and it being sensitive to voltage drop.
So this year I decided to re-route some other accessory power feeds and had the dash open. It was then that I noticed that the previous owner had run heavy gauge wire "towards" the C80 (so far so good) from the switch, but then for some reason spliced in an inline fuse on the power feed with what looked like 18 or maybe 16 gauge wire. Really thin stuff. It was way down in the dash at the end of the power feed coil to the C80 and was out of view. I had never pulled it up before.
So I rewired a proper fuse right at the switch, removed the thin wire and spiced the C80 wiring direct to the heavy feed. And now its properly fused and wired and everything works properly. No shut downs, no restarts.
