Whatever you pay for a tester would be paid back on this job alone. ;)

So far you have bought solenoids off eBay, which you may not need...
and are talking about a switch... and wire...and drilling holes in the engine cowling... and your time...and you still do not really know where, or what, the problem is.

A multimeter would get you to the actual source of the problem in 5-10 minutes.

That said, YES, you could run a push button on the dashboard with wires that run as you said. Be sure to fuse the hot, and be aware of the safety issues of having bypassed the lock-out switches. Obviously the ignition key needs to be in the "run" position.

Re: 1975 evinrude will start if the two hots at soleinod touched with a piece of wire

ok got a meter and on the ohms setting i am getting power fromthe safety switch when the button is pressed. I am getting power to the ignition switch, but when testing the solenoid I am not getting power to the white wire on the solenoid and i am hooked to the ground wire on the solenoid. hoked to the ground on the solenoid i get readings on the battery hooked to the top of solenoid and power to starter side but not on the white wire on solenoid.

Were does the white wire on the solenoid come from? I was thinking it is from the neutral safety switch in the throttle box. Ive tested the safety switch and with button pressed it shows power and from the safety switch to the key switch but from the key switch to the solenoid when its pressed nothing? For this safety switch to work shouldn't i get power to that white wire on solenoid if the controls are in gear? With no power through that wire on solenoid, that means the motor is in neutral and can be started right? I have a 2 new solenoids coming hopefully they will be tomorrow?

Does that mean the attachment wouldn't work for you. I tried on my laptop and it worked ok.

the neutral safety switch on the motor will be somewhere close to the shift linkage. It does have one. What hp is this motor?

I have looked all over my motor and havent seen anything like a switch on my motor and for that anything even close to the linkage.like i said it was running fine and the safety in the control was working good then all the sudden it stopped starting with the key. Its a 1975 50 hp model 50573b evinrude.

ok got a meter and on the ohms setting i am getting power fromthe safety switch when the button is pressed. I am getting power to the ignition switch, but when testing the solenoid I am not getting power to the white wire on the solenoid and i am hooked to the ground wire on the solenoid. hoked to the ground on the solenoid i get readings on the battery hooked to the top of solenoid and power to starter side but not on the white wire on solenoid.


Maybe some problems here using the meter.

1) If you are on the "ohms" setting, you should not be checking for "power"...that is a fast way to damage your meter.
2) Ohms setting checks continuity in wires...lets you know if there is a break between point A and point B.
3) It is probably safest to check continuity with the battery ground disconnected. That way you don't need to worry about accidentally putting 12 volts through the ohmmeter loop.

4) Checking for voltage. use the DC voltage setting .

I would suggest 3 tests to start:

Disconnect the primary (+) wire from the solenoid.

1) Test the solenoid primary circuit...with meter set to Ohms, test between the two primary posts on the solenoid.The reading should be less than a couple of ohms. If you get a very high reading, the solenoid is toast.
2) Test from the negative primary post on the solenoid to a good ground on the engine. The reading should approach 0...zero. If it is higher, the problem is with the ground.

3) If both those tests are OK, now check for correct power feed. Set meter to DC volts.
Test between the positive lead which you disconnected and a good ground. Positive lead of meter on the wire, negative lead to ground post on solenoid. You should get 12V.

I have seen a solenoid's internal contacts get corroded & they would make enough connection to start if used quite often, but let it set for a few months & the contacts corroded enough to not allow the solenoid's magnet to pull it tight enough to make enough continuety to allow the starter to engage.

Re: 1975 evinrude will not start with key but with pull cord?

Tested between to battery hot and starter hot on solenoid and was not getting anything on ohms meter or dc with power on. The solenoid was bad. Replaced with the used one i got from ebay and she back starting. I paid $5.00 on ebay for these solenoids and they sent me three and all three are good. The solenoids are listed free just have to pay shipping on them! There used but there good.
