1964 Evinrude Starflite 75hp

[waterlogged59]

Hey Guys

I really need your help with this one. I have a 1964 Evinrude Starflite 75hp with Electric Shift. I recently Replaced the Entire lower unit. I put all the wiring back together from motor to Switchbox to the dash ignition. I am getting nothing!! When I turn the key nothing happens. I have followed all diagrams and wired it to match the diagram but nothing. The Ammeter isn't even moving either when I turn the ignition. Does anyone have any idea what could be causing this?

Do you have a 20 amp fuse between the ammeter and the ignition?

Re: 1964 Evinrude Starflite 75hp

Yes it does have a 20amp fuse in between the Ammeter to the Ignition spot on the key. I am not sure why it isn't getting anything from battery.

Are you getting 12v at the ignition?

Re: 1964 Evinrude Starflite 75hp

Is your battery good ?? Are all the battery connections clean and tight ??

The battery connections are good. I am also concerned with the battery quality. Heres my issue. I have all my accessories on separate lines from bus bars going to battery and they come on just not the ignition. Would the accessories be able to come on with a battery that is sub par or about gone? Would the engine at least turn over or the ammeter twitch when the I turn the key?

Maybe you should get the battery tested or replace it if you question the quality of it.

Re: 1964 Evinrude Starflite 75hp

You indicated you have the wiring diagram. If that is so, then use it. What I'm saying is use it and a voltmeter to determine if you have proper voltages at the various parts of the circuits.

EDIT: That motor has a fairly complicated electrical system with the big junction box, etc. If you don't know much about interpreting wiring diagrams and testing, you may need some help. It would border on futile for any of us to sit here and tell you how to do it. We would only be guessing.

Thanks for you guys input. I have followed the diagram to a T. So I will check the battery and Volts at the Ignition. I was just curious to see from you guys past experiences with the motors if it could be a possible solenoid, voltage regulator, capacitor, or rectifiers. Would those even be a possible cause to it.

Re: 1964 Evinrude Starflite 75hp

Just use common sense and look at the parts associated with whichever system is giving you the trouble. Of course that is the starting system. So....obviously the voltage regulator (charging system) and rectifier diodes and capacitor (also charging system) probably have nothing to do with it.

Solenoid, maybe. Safety switch, likely. Anything else connecting them,.....well that's what you are doing voltage tests for. Test, don't guess. And don't replace until you know it is bad.

Re: 1964 Evinrude Starflite 75hp

I just tried to turn it over with a new battery and still to no avail. I am not sure whats going on. I have looked at all fuses and they look fine. I will look alittle further into the wiring compared to the diagram I have as long as I can work around the wasps that keep making nests around the wiring!

Re: 1964 Evinrude Starflite 75hp

Will the motor crank with boosters to the starter ?------Have you checked the safety switch found on the distributor ?

Re: 1964 Evinrude Starflite 75hp

There's a 60-amp fuse in the junction box. Have you checked it? It doesn't look quite like a typical fuse. Its rectangular in shape. Sorry, but the system doesn't seem to allow me to upload pics.

That is a very often overlooked item. But with all due respect to yorab, the 60A fuse has nothing to do with the starting circuit. It is in the alternator / charging circuit.

Re: 1964 Evinrude Starflite 75hp

Ah, noted.

 

[waterlogged59]

Re: 1964 Evinrude Starflite 75hp

So I have rewired the everything based off the diagram and still nothing. The fuse in the junction box is still good as well. I also jumped the two posts on the solenoid in the junction box to see if anything would happen and nothing. even when I turn the key to the on position nothing happens to the ammeter or tach. No movement at all. brand new battery as well. I am not quite sure what to look at now. I will check the safety switch on the distributor. Do you mind helping understand the steps for boosters to the engine?

Re: 1964 Evinrude Starflite 75hp

On your wiring diagram if it is the proper one, and on the engine itself, the Positive (+) battery cable leads to one of the large starter solenoid terminals.

Now, at that same terminal there is another wire, somewhat smaller than the battery cable. What color is that smaller cable and where does it lead to and attach to?

 

[waterlogged59]

Re: 1964 Evinrude Starflite 75hp

Yes it's green and runs to the ammeter.

Re: 1964 Evinrude Starflite 75hp

Here is the wiring diagram for your motor. If you look carefully at it, you will see that the starting primary circuit flow is from the large battery cable terminal on the starting solenoid, through the green wire, to the ammeter, through the ammeter to the brown fuse holder wire, on to the key switch.


From the key switch (in start position) current flows through the white wire back to one of the small posts on the solenoid, through the solenoid's primary winding, out the other small post and second white wire, going to the multi terminal plastic plug.

Coming out the other side of the plastic plug, white wire continues on to the safety switch on the distributor bracket. If the throttle is set to a safe starting speed, the safety switch will be closed and ground the white wire, completing the circuit and the solenoid will contact and the starter will run..

Now...........it is up to you to take your voltmeter and check for voltages at every point along the way, till you find the problem.

Oh, I almost forgot. The NEGATIVE battery cable is part of the circuit. Don't ignore it.

If you pass this, you have passed a portion of your course in Electrical Circuits 101. It's a bit much to expect us to sit here and guess where the trouble is.

Re: 1964 Evinrude Starflite 75hp

OK, have you had time to ponder on my previous post yet? Here is a BIG clue. You said the ammeter does not move when you turn the key on. That means electricity is not flowing through it to the red wires on the key switch. Why not?? Probably because there is none present at the green and brown wires. OR the fuse is blown. OR there is a problem with the battery cables.

1. Check BOTH battery cables. Shiny bright clean and tight?
2. Check voltage at green wire on ammeter. Should be 12V. If not, find out why not.
3. If you have 12V on brown wire on key switch, check voltage on the red wires stack when key turned on. Should be 12V. If not, but you do have it on the brown wire, bad key switch.
