97 Johnson not turning over/ battery strong

[rangerbobby]

Hi everyone.
Initially, I thought I had a dead battery, but soon found my batttery seems fine. The ignition does not turn over at all, and the trim control on the throttle, as well as the trim control on the motor are not getting power. All guages, lights and the trim control at the front of the boat work. (same battery)
The motor is a 1997 Johnson 90 hp, on an 18 foot Sea Ark fishing boat.
Any suggestions would be greatly appreciated.
Bobby

Have you removed and cleaned all your battery connections. Dirty connections can provide enough current to power lights but not enough for the starter.

Yes, I went through all connections, and made sure they were good. Does the fact that the tilt controls on the throttle and motor are also not working? Might there be a fuse somewhere?
Thanks.

in the picture below you will see the fuse, it is in the small red connector on the lower right in the picture. this is a 20 amp fuse that controls the ignition circuit. could very well be your problem.

this is for future reference,
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.

Tashasdaddy, sure enough, the fuse was blown. I replaced it, and was back on the water.

Thanks!
