    I had to put a new motor on my John Deere Quik Trak and what I decided to go with was a Kohler. The problem is that it had a Kawasaki on it and the wiring is not at all the same.

    I was hopeing the someone could help me get this straight. I do not know the first thing about electrical so I am stuck.

    Thanks for any help, James

    What wires do you have coming from the Kohler, and from where would help.
    We can get it done, but it'll be a little slow without me seeing it.
    Does the new eng have a fuel solenoid on the carb?
    You'll probably have to snip a few plugs and splice the wires together cause the plugs aren't compatible but they should have the same functions.

    You've got to have :
    12v with the key on to the fuel solenoid
    12v with the key on to the rectifier/regulator (and not the same wire)
    ground with the key OFF to the kill wire or terminal
    (remember that any safety interlocks will cause this wire to be grounded even with the key on)

    That's the basics, and should run, but I don't know what accessories you have to power.

    OK, I have got everything wired. I think. But I am having to use a separate solenoid but it has 4 post. I know what the 2 large ones are for and one of the smaller ones but do I need to do anything with the other smaller post?

    Thanks,James

    This last small post must have a wire hooked to it and the other end hooked to one of the solenoid mounting screws, Without this post hooked to a ground point the solenoid will not work.

    Well I got all the wiring right I think but when I turn the key the engine starts to turn but then stops. Like when your battery is low. I put a jumper on it and the same thing. I tried the clutch and it engages. Not sure if I missed something.

    Thanks,James

    Looks like it may be time for some numbers James.

    Deere model and serial #'s

    Kawi model and spec #'s along with the Kohler model and spec #'s.

    I will need to see what your working with here.....

    Will it spin over with the spark plug(s) removed ?

    James, Can you answer my question before I go to racking my brain on this one ?

    No it is the same result with or without the plugs in.

    Thanks,James

    Can you put your jumper right to the stater and get it to spin ? It sounds like you have it wired correctly.

    Is this a brand new engine ?

    When you installed it did you make sure the slots in the pto clutch aligned with the pins on the rear bracket ? It sounds like something is binding the crankshaft in which the clutch could if not aligned on the pins.
