I have had problems with my motor, Shaking , blowing motors and such, doing my second rebuild now, and we haven't found the original culprit that has been the root of the problem. I started thinking about things that happened before all the problems with my motor. Well one day I went to crank up the motor, and the batterey was dead it was low on juice, and the dumb thing I did was to take jumper cables and run them from my trolling motor battery, and jump my starting battery. Is this a no no, and what would be the parts that this could have damaged. thanks , Jimmy learning the hardway and the expensive way
