My dad asked me to look at some stuff on his boat. I don't think was used a lot last year. This year it's having issues, all electrical related.
main engine had some issues and would start. went to test trolling motor thinking well if engine has issue again there will at least be something other than oars to get back with.
It's a larger minn kota power drive motor, fish finder sensor, control pad for all the controls even steering. Some reason the motor plugs into a port on the boat, control pad has own interface too. I tested using the battery gage on the motor to see if had power, nothing. disconnected line from battery to plug, and used fine file to get the corrosion, etc. off. Used file to do same thing on the motor plug, and the control pad connections, as nothing was working. I did that until looked to be quite clean. Then I got the steering part working, but the drive motor wouldn't activate. I checked the connections, all was fine, so I popped open the base unit, and looked at controller.
Area around controller board was full of spider webs, etc. I tested for voltage in and out of board. Input was fine, but no output even when I pressed the full speed pedal n the control panel. That made a relay trip, but no output. Checked the terminals, filed off until were clean still nothing.
I want to say the control boards shot as the full speed button fails, and the just trolling, and speed adjustment also fail. The speed control I think is a PWM setup, which tells me A something's up with a connection, which I doubt or the boards fried. I doubt connection as were clean, and relay tripping, but no output tells me something's up in the board. There's no way to fix the board as is all covered in resin (or something plastic like).
Looks like you can get just the control boards for like $75 USD, but because had issue with connections I'm not 100% sure that is the issue, or only issue.
Kind of looking for tips either things I may have missed, or just an idea my guess is correct. I find odd how 2 yrs ago it worked fine, all the sudden something like controller fails. I'd kind of like to test the motor directly just see if maybe something isn't shorted out, and that fried the board. Not sure that's ok to do though, I would guess the motors basically like what they use for starters, or tilt/trim, simple 12V DC motor of some sort. (only 2 wires, so seems like only thing could be.)
