I engine an 82 johnson 115hp engine on the back of my boat. I lucked out and got the boat for 600 dollars bc they thought the engine was frozen. Well, after just a little bit of work I got the engine to run. The only problem is that I can only pull start it. My first thought was that the solenoid was bad, and I replaced it. I also replaced the old battery, so I know I have the cranking power. I replaced the solenoid, and it would not start still. I tested the path of electricity and my diagnosis pointed to it being a bad solenoid, but it is brand new. Does anyone have an idea on where I should look next??? Any info would be be great.

Re: 82 johnson ignition problems!!!

Hey Fishin..I thought I would chime in. Is the solenoid a four post type like what you would find on an old ford? Two large posts on each side and two smaller ones on top? If so, all I did was swap the two wires on the top, and the boat started up. I had the same problem that you were having..just a thought...

Re: 82 johnson ignition problems!!!

Yes it is the same type. Did you have the ground on the bottom and the neutral start switch (yellow and red strip) on top? this is the way that I have it right now. If you remember, please drop me another line!!! Thanks!!!

Re: 82 johnson ignition problems!!!

hmmm..It's raining out right now, so I cannot go look at mine. I believe whoever had the boat before did a little rewiring, so I didn't have the wires with tracers on. Does the box that your solenoid is in have a cover? I found the wiring diagram on the inside cover of mine. With the exception of the two top posts (one ground and one to the starter) the diagram was correct. I had my ground wire (from the motor) going to the top post on the same side as my positive battery hook up. Does this make sense or help at all?

Re: 82 johnson ignition problems!!!

that sounds like how I have mine hooked up. There was no diagram, but I have the book. The only problem that I had with that is that it had the battery and starter wires backwords in it. The starter has a diagram, so i hooked it up that way. Thanks for you help.

Re: 82 johnson ignition problems!!!

With a test light grounded first check for voltage on top solenoid post. Next check for voltage on top small post with key in start position. Third make sure bottom small post goes direct to ground (there should be a short wire that bolts fom the solenoid to the block). If after all these checks you don't have voltage at the bottom post with the key on your solenoid is bad. If there is voltage at the bottom post your stater is bad. If the starter is bad remove it ad the bottom plate to check the rushes for wear.

Re: 82 johnson ignition problems!!!

Thanks for the input, but I have done that. That is why I am perplexed!!! It is a brand new soleniod, but like you said, if I have no power at the bottom post, the solenoid is dead. I was just wondering if there could be anything else seeing how it is a new solenoid! <br /><br />Thanks again!!!

Re: 82 johnson ignition problems!!!

If you have power at the top always, power at the first small post with the key on start and a good ground going from the bottom terminal to the block, then the solenoid is bad. Take it back and get another one.

Re: 82 johnson ignition problems!!!

I was not able to get the power to the second post. Could that be b/c of the neutral start switch?

Start with the simlpe thing have you checked the key switch? This happened to me the boat sat outside and after the first couple of starts the key went out found it after replacing everthing else

Re: 82 johnson ignition problems!!!

There should be a yellow/red wire at the solenoid, which is hot when key in in start position. If this wire is not hot, check 20 amp fuse in engine harness.

P.S. I am new at fixing boats!! Could you give me a good idea on where to find that fuse?

Re: 82 johnson ignition problems!!!

It should be right near the big red plug for the harness. It might look like a rubber connection plug.

Close to starter solenoid, looks like small red primer bulb.

Re: 82 johnson ignition problems!!!

thanks for the info guys!!! I will be sure to check it out this weekend. It may be a little time before I know b/c I am judging a shark fishing tourny in Port Aransas this weekend, but I will be sure to let you know. And if any of you have an idea of what may be goin wrong, please let me know!!!!

Re: 82 johnson ignition problems!!!

Fool,<br />I didn't quite follow all the results from the previous posts, but I'll lay out a step-by-step testing method that I would use:<br />1) Disconnect both small wires from the solenoid.<br />2) Use an Ohms meter to measure resistance between the two small terminals. I haven't got a clue what the correct reading would be, but it should at least show continuity. If your meter doesn't move when you touch the probes to the terminals, you have a brand-new-but-still-bad solenoid.<br />3) Test the ground wire for the solenoid with the ohms meter. It should read zero ohms from the terminal to the engine block.<br />4) Have an assistant turn the key to the start position. Measure voltage at the red/yellow wire. You should be getting at least 12 volts. <br />5) Reconnect the wires to the solenoid. Repeat test 4 with the wires connected. If the solenoid doesn't click, but still shows 12 volts at the red/yellow wire terminal, test for voltage at the other small terminal. There should be none. This proves again that you have a brand-new-but-still-bad solenoid.<br />6) If you got no power at the solenoid on the red/yellow wire, start tracing the wire back to the key switch. Be sure to watch for someone else's poor wire locating. The wire could have been cut by abrasion around a sharp corner.<br />7) Put the volt meter on the posts on the back of the key switch. Make sure the "start" terminal gets juice when the key is in the "start" position.<br /><br />Hopefully, at least one of these steps will isolate the problem.<br /><br />Ron
