Both tachs stopped working

[tsturm]

Well I spent all weekend replacing the connections that were looking rough and that solved my voltage drop issues, the bad news is that my tachs still dont work, I will keep looking things over and find the issue eventually but do have another good question for you guys.

There is a 50 amp thermal circuit breaker in the battery box and I have no idea what it goes to, the only thing on the boat that I could imagine that would need something like this is the Trac pot puller but it already has a 35 amp fuse in-line, what do you think?

Anchor windless?? follow the wire?
Look for disconnected, corroded bullet or spade connectors near coil packs (under cowling) on motors, at throttle & near tac's.
Is this a red stripe 22 formerly named Money Pit? :beer

No windless on the boat and these is no wire coming off of it. No apparently it has been Blue Dawg since day 1.
