maximizer to motorguide

motion dynamics carrys a controller that will convert to variable speed. not sure how water proof box would be but if my motor was not variable speed I would try one.

Thanks for the info, have the ebay unit on 'watch' since it's a buy it now i'll probably get to see it disappear. Have found a schottky diode and a
1n4001 that look burned so hope to get this one fixed this afternoon.--shu

When I had a Maximizer, the directions said to hook the trolling motor directly to the Maximizer, put the TM rheostat on High and adjust speed with control on Maximizer. Mine had a coiled cord that would stretch to my seat.

That's what i've got except for the instructions and the clips that go to the battery??? were cut off, can't tell which wires go to the battery and what goes to the motor so must have got it backwards as the 'protection' diode is fried have ordered the schottky diode but still don't know for sure where which wires go.

In some power supplies, the clamping diode is usually across the input to cause a fuse to blow in case of reverse polarity. What size fuse you have from battery? The fuse should have popped and not smoked the clamp diode.

Just checked and don't see a fuse must have been left out when the carpet was redone. What size needs to be there?? All used stuff and no info. --shu

Mine has two terminal. Pos and Neg where the trolling motor connects. The power cable from the battery goes inside the case.

Which wire going inside has the +12v on it the smooth or the one with the ridge? Always thought has ridge has volts. Thanks for the info. None of the wiring diagrams found show what size fuse to use only one shows a 65amp breaker.--shu

Two things to consider when fusing the TM. First the ampacity of the wire and second the stall current of motor. What thrust is the TM? I believe there is a fuse chart on the MK web somewhere.

Trolling motor is a Motorguide 743 which has 43# thrust, wire is 10 guage stranded automotive type.--shu
