bad switchbox.


EDIT: Swap the switch boxes with each other and see if the problem changes sides. Should be it though. Each box runs a bank.

Or Bad stator....You can swap the switch boxes around and see if the problem moves with them..

hey thanks a lot guys,,,that will make Grizzly very happy,,
I belong to a fishing website,,and as luck would have it I am the local free outboard machanic,,the moters are mostly old little twins and trips but every now and then one of the guys brings or asks me about one of the big new mills and with all that fancy stuff they put on them now days I am a little hesitant to give advice or work on them ,,,but you guys are a great help!
so if it turns out to be the stator is their a rectifier that should be changed also?
thanks again
