Motorguide Troubles

[Lance34]

The last few trips out my Motorguide 45 thrust will work fine for about 1 hour or so and then after that it will start to slowly loose it thrust. You turn it up to five and it runs like it set at two after while. The battery is about a year old and I have had it checked out and it's good. I have a graph on the bow that is wired through it and has been working fine since the day installed two years ago until now. When I turn the motor up to five the graph will shut off but once I let off it turns back on. Called a service center to get any idea on what I could do to troubleshoot it myself and all I got was maybe the windings but wasn't for sure until they could tear into it which would run $100. I thought I would post here to see if any of you have any idea on where to start or should I save $100 and repair cost and just get a new trolling motor.

I'd say your battery is bad. Same thing has happened to me a time or two. I run a Motorguide 24 volt trolling motor and have experienced the same problems. A couple things I did that helped was to make sure my trolling motor leads were below my depth finder leads. Also, make sure that your graph is turned off at the end of a trip. I forgot to do this once and ended up with a short trip the next time out. Are you charging your batteries after each trip and topping them off before the next trip?

Thanks, yes I do charge it after and before. Looking to find a battery to borrow to be sure it's the battery and not a current issue. Thanks again
