Re: 1996 50 hp won't turn over

Thanks guys. I have tried all your suggestions and still can not ge power to the motor. There is power on the bottom of the solenoid and nothing else. I can not even ge the ptt to work. Seems to be dead at the solenoid. Help please.

Get an OMC shop manual

Re: 1996 50 hp won't turn over

Thanks walker, but I thought that someone even maybe you could of helped. And by the way I have a manual and not as well informed as you are. I apologize to the others for my comments.

Re: 1996 50 hp won't turn over

I wasn't being a smart-***. With a good manual you would have already figured the problem out. A manual will take you through the circuit testing step by step. Its very hard to diagnose electrical problems over the internet.

Re: 1996 50 hp won't turn over

My apologies to you, short comments like that can be misleading and i apologize for the comment. I have followed a trouble shooting guide and still have no power. I am at the point of a new motor. Sorry

Re: 1996 50 hp won't turn over

Kiya <br />Did you ever find out if you are indeed getting 12 Volts to the starter when you turn the key? If so, I'm betting that the starter selonoid is bad. Replace it. If this does not do it, I'm thinking that the neutral safety switch is defective in the control box. Open up the control box, find it and bypass it. If this does not work, head to the ignition switch and check it out. You have narrowed it down to either the selonoid, ignition switch, neutral safety switch or the wiring from the control box to the starter(Doubt it's that). Start at the selonoid and work back to the control box. You will find the cause. You just have to be systematic when you troubleshoot

Re: 1996 50 hp won't turn over

Rick. Systematic steps would be beneficial. I'm jumping around like a fish out of water. Now that the Walleye opener is past I will settle down and check it out with your instructions. I am believing also that it is the solenoid because I can et nothing passed the battery terminal on the bottom of the solenoid. I shoould also change my screen name, because Kiya just does not go with boating. Thanks Rick will let you know.

Re: 1996 50 hp won't turn over

First of all you said you are getting power to the battery post on the starter, you should also have a lead at the positive post on the battery that goes to the ignition switch or fuse block in the front of the boat, check the ignition switch and see if you are getting power there if so see if the switch is putting power to the post marked S when you turn the key to start, if you have power there go to the control and see if you are getting power to the neutral switch, if you have power there check that power is going through when the motor is in neutral, then go to the solinoid and have someone turn the key to start and see if you are getting power to the small post (you said the fuse was good) if you are getting power there the sol. is bad.

Re: 1996 50 hp won't turn over

Final kick at the cat. I disconnected all wires from the solenoid. No continuity between the two large terminals(no needle deflection). Hooked power to the signal terminals and heard a solenoid click. Took another reading across the two large terminals and had a full needle reflection on the ohm meter. Tested the two large terminals after removing power and no needle reflection. Solenoid no good, Correct?????

Re: 1996 50 hp won't turn over

Buy one. A Ford type solenoid will work if you don't want to spring for an overpriced marine type. Get the same type at Canadian tire. nevjb

Re: 1996 50 hp won't turn over

Thanks man i am going to a Canadian tire on Thursday and will pick one up. Will let you know what happens. Thanks again. Just noticed that a guy from Reno Nevada knows about Canadian tire. Cool

Re: 1996 50 hp won't turn over

Kiya,<br />Hold on a second bud....<br /><br />You said:<br />I disconnected all wires from the solenoid. *** OK, good start...<br /><br />No continuity between the two large terminals(no needle deflection). *** That's perfectly normal<br /><br />Hooked power to the signal terminals and heard a solenoid click. **** Thats good= Good coil<br /><br />Took another reading across the two large terminals and had a full needle reflection on the ohm meter. **** That's Good= Internal Contacts Initially Good (should test under starter load) <br /><br />Tested the two large terminals after removing power and no needle reflection. Solenoid no good, Correct????? *** Nope, solenoid sounds like it's operating like it should. Your meter should read an open circuit (no contact)<br /><br />Before we go any further here, I must know if your solenoid has 1 or 2 smaller posts. We already know for sure that the solenoid has 2 large posts (one to the battery, the other to the starter).<br /><br />BTW, don't replace the starter solenoid with an automotive type. Marine solenoids are sealed to prevent internal sparking from igniting any fumes under the hood. The last thing you want or need is to hear the whoomping sound!

Re: 1996 50 hp won't turn over

well better back track, first go to battery lead are you getting power to the battery post on the solenoid? if so trace the exciter wire back to the neutral switch are the wires good or corroded? are you getting a reading through the neutral switch? if so go to the fuse block check the fuses, if they are ok go to the switch check it for continuity, also check the neg. battery lead for corrosion and is it good to the motor. if all that checks out and the solenoid and starter are good there is no reason for it not to work unless the fuse you said was good at the motor isn't.

Did you Ohm it out when power was supplied to the small terminals? (And by the way, it's sounds like a 2 terminal set-up). Try this. With all the wires hooked up to the selonoid, have someone turn the key to start and measure voltage, not Ohms, at the small positive terminal going to the selonoid(Ground to terminal). If you have voltage(12 Volts), you are getting close. You want to measure voltage, not Ohms when doing this process. If this is the case and you get 12 Volts to the small wire,but no start, I still think the selonoid is bad or the wiring is corroded and cuts out under a load. The internal contacts of the selonoid could also be bad. Just because it clicks, does not mean it's good...

Re: 1996 50 hp won't turn over

Xcusme is correct in saying a marine solenoid is sealed . I have checked the Ford type closely and tried to get water into them by submerging them in water and there doesn't seem to any water getting inside. By the way I've run a Ford solenoid on the same motor for twenty years after the marine unit hung up on the second use. Maybe just a coincidence. Let me state again that Xcusme is leaning to the safer side of things and is technically correct.. nevjb

Re: 1996 50 hp won't turn over

I would prefer to use a marine type. I am not a chance taker and taking my nieces and nephews with me in the boa I want to be darn sure there ia no fireworks behind me. Safety first is for me. I will try the suggestions and see what happens. I am just missing something. Maybe this is the wifes way of saving gas.

Re: 1996 50 hp won't turn over

Kiya, jump a hot wire to the small posts on the solenoid one at a time. Just touch the terminal. if the starter engages then your solenoid is good.

Re: 1996 50 hp won't turn over

Kiya,<br />I was saving this next bit for another time, but you may want to take a gander.<br /><br />I figure a picture is worth a thousand words with an explanation of how this circuit<br />works. The circuit may look confusing at first, but it's really a simple concept if<br />broken down into it's parts.<br /><br /><br />

<br /><br /><br />The main parts are:<br /><br />12VDC Battery<br />Ignition Fuse<br />Ignition Switch<br />Neutral Safety Switch<br />Starter Solenoid<br />Starter<br /><br />Lets start at the battery and trace the path of the voltage thru the starter system with<br />tips along the way.<br /><br />Since this is a negative ground system, the negative side of the battery is ground.<br /><br />The positive side of the battery supplies 12VDC voltage to one side (large post) of<br />the solenoid at Terminal #6.<br /><br />The ignition supply wire is also connected to this large post of the solenoid.<br />The ignition supply wire may be connected directly to the positive battery post in<br />some applications instead of the solenoid terminal #6.<br /><br />Voltage travels thru the ignition supply wire, thru a fuse and into the ignition switch<br />at terminal #5. The voltage stops at this point since the key is in the OFF position.<br /><br />When the ignition key is turned to the Start position, the voltage leaves the ignition<br />switch on terminal #4 and travels to one side of the Neutral safety switch (red A).<br /><br />The function of the Neutral Safety switch is to insure that the motor is shifted in<br />Neutral before the motor can start. The neutral safety switch is normally an Open<br />Circuit (no voltage can pass thru it) until the motor is in neutral gear.<br /><br />When the motor is shifted into Neutral gear, the switch closes allowing voltage to<br />pass thru the switch to ( red B) , and then on to terminal #3 of the solenoid. The<br />voltage enters the solenoid at terminal #3 and then out terminal #2 to ground<br />(terminal #1), completing the circuit. When the solenoid gets voltage and ground<br />(terminals #3 and 2 respectively) the solenoid closes. Usually a click can be heard<br />when the solenoid energizes and it's internal contacts close.<br /><br />When the solenoid closes ( is energized), voltage from terminal #6 is passed thru<br />the solenoid to terminal #7 and on to terminal #8, the starter. The voltage continues <br />thru the starter windings and finally to ground thru the starter case itself which is bolted to ground.<br /><br />This completes the circuit and the starter should spin.<br /><br />------------------------------------------------------------------------------------------------------------------------------

Re: 1996 50 hp won't turn over

Xcusme, thanks so much. I see one difference in this wiring diagram compared to my motor. The difference being the Ignition Supply wire is connected to the same large terminal on the solenoid. I am going to try this procedure tomorrow or Thursday when time permits. Its going to rain for a few days and Ia m working on the restoration truck in the garage. Will post my findings asap. Thanks a million.

Re: 1996 50 hp won't turn over

My apologies gentlemen for your replies. Due to a family business emergency I have not had time to deal with the motor problems. I will get back at it when this situation is over. I sincerely hope that all goes well and I will be at the motor again within a few days. Sorry for the delay.
