Boat is back together, and everything is functional.
Long story short, there was a female lead that got plugged in by some one (me) but I don’t know who would do such a thing.
Last Saturday my graph would power down when the boat got a good smack from a wave while on Lake Michigan.
It was a loose pigtail on the ground or power.
I crimped both, put them back and saw a loose pigtail.
Well the only place it reached was power or ground BARELY.
So I plugged it in thinking I had unplugged it.
Long story short, it’s a power pigtail for a 3 way switch. Power-Off-Auto. So the pigtail would power the “Auto” as well.
After figuring this all out, I have a new 750GPH livewell pump, and some knowledge of 12 volt wiring.
That pigtail was wrapped with electric tape and tucked out of the way.
The learning experience was not with out a cost though.........
All the blown fuses......... lol
