Solenoid Pinout??

[tcooke]

I have a 1978 Mercruiser 140, it has the different type of solenoid that isn't like in the wiring diagrams in my manual. I is the one as seen in this pic as num,ber 36A http://www.boatfix.com/mercag/parts1.asp?partno=1586&block=0&img=CRUISER/68573/WIRE.pdf

Does anyone know what the pinouts are on it as they have no markings.......does it even matter as long as the large and small connections are seperated?

Help please I am trying to get my newly rebuilt engine started today.

Well, now that we know what kind of solenoid you DON'T have, can you post a picture of one like you do have?
What is this solenoid for start, or trim.
Is it one like pictured here.

Sorry Don, I edited my first post, what I meant to say was that it isn't like the on in my manual. It is the one in the pic mentioned above, non-traditional type.

Re: Solenoid Pinout??

I guess the first question is what kind of solenoid do you have. A lot of them look the same, but work different.
Do you have a PN for the one you bought? and What brand, like Sierra, Arco, Mallory, etc.

If it's internally like the one shown in your manual, the big wires and little wires should do the same thing.

The solenoid is the slave starter solenoid I believe, it looks the same as the one I posted above in the link (#36A - PN 89 853654A 1, not #36 which is the traditional looking solenoid).

This one here...

I did not buy it as it came with the bell housing/motor I just bought. Unfortunately the solenoid has no pin identifactions on it like other solenoids I have seen. Internal/External, how do you know the difference?

Check the small terminals, see if there is an I by one and an S by the other. If there is, you want to put the Start wire (Yellow/red) from the ignition switch to the S terminal. Ground will be through the base, and the I terminal will not be used.
If there are no letters, one of the small terminals will be yellow/red from the switch, the other will be ground. When the key is turned to the start position you should here the relay click.
On either type, the red/purple wire goes to one of the big terminals, the yellow red wire going to the start terminal on the starter solenoid.
