Old 30lb Motorguide

[JasonB]

Got an old 30lb Motorguide Pro with a boat I bought. It doesn’t work, so I decided to tinker with it. This model only seems to use a speed wheel, a micro switch, and a 3 way toggle. No circuit board. The motor spins with what I would call normal resistance by hand.

It has Black/red 10ga wires and blue/yellow 14ga wires.

I located the black/red wires that go direct to the lower unit and plugged straight to known 12v to bypass all the stuff interior pedal and got nothing. Does there need to be some level of voltage on the blue/yellow?

I pulled the lower unit apart. Enough to take a look. Out was clean+dry, with no hint of water intrusion. Magnets were in place.

I’ve never worked on one of these before, so I’m stumped. Maybe something bad with the items in the front of the lower?

What your doing sounds like a fun project, but in reality, the old electric trolling motors were no where near as efficient with the battery power as newer models are. I also enjoy fixing up old stuff just to say I got it running again ! If you actually plan on putting this into service, getting a newer model may be well worth the investment in greater efficiency of the battery power. Just some food for thought......

Valid point. It’s effectively for the enjoyment of trying to figure it out. I’ll disassemble most anything once, and have never had occasion to tinker with one of these. They look deceptively simple enough.
