starter, motor not turning over

[slowtroller]

Hi,
I have a 78 model Johnson 25 hp motor with remote electric start. Sat up about a year and now it will not turn over with the starter. I had the starter rebuilt a few weeks ago. It spins over great with the plugs out, but when I put the plugs back in it will engage but will not spin over. I had what I believe was a good battery hooked to it. And even put a jumper box on it to see if that would help give it more torque. Still nothing. I can spin it over with my hand fine so I know the engine isn't seized up. Any ideas would be greatly appriciated.

P.S. If anyone has the wiring diagrams that go from the remote start to silonoid that would be great.

Thanks again.

Re: starter, motor not turning over

90% of starter problems are bad connections. remove and clean both ends of the battery cables, so that they are shiney, also the cable from the solenoid to starter. check for nicks in the cables. and make sure the connectors are on the wire good. the cable tend to corrode from the inside out, if nicked, corroded wires, and connections, heat up and cause resistance to the follow of electricity, thus the starter doesn't get enough. you can also take jumper cable pos battery post to large post on starter. with a good connection, the engine should spin. then if the starter is good clean everything and retest. then trouble shoot solenoid. starters can be rebuit at a starter/alternator shop, much cheaper than a new one.

Be sure the cables area connected to the correct battery post. crossing cables, usually blows the rectifier, and can blow more.

also have the battery load tested at the auto parts store, free, i've had new batteries go bad
