RE: elec. boat ran last year, not now???
No water in the boat. It was always well sealed.
Yes, there is a wire soldered to each shaft outer. It was on each of these outer shafts where I connected the wires. Not the inner shafts .
Should I have tried to connect the "inner" shafts with the wire?
Are you suggesting that part of the battery pack might somehow be bad? The battery tester I have has positions for 6v and 9v, but this battery says it is 7.2v there areonly two wires coming from the battery. When you are suggesting one "cell" might be defective, you are referring to the battery, correct? Or something else?
