Thanks for the replys! It turns out that the unit locks up when I start the big motor. It is only reading 9.6 volts on the unit even after just taking it off the charger. I have new batteries and a MinnKota digital charger. Also my 1197 running on the same battery reads 12.5 volts. I tested the voltage at the mount and it reads 12.5 volts so it has to be from the mount or the unit itself. I will try the slight bending of the prongs and see what happens.
