Engine will not shut off

[acudanut]

Just Installed new wiring harness. Engine wont stop. idea's ?

[bazookajoe]

hot lead in constant contact with distributor....i would leave the distributor disconnected till you find the mistake in the connections to save the coil.

[acudanut]

I wonder what I did wrong ?

hi

the wire no 12 ignition come straight from the ignition switch
it go also to the alternator as no 568

at the switch the two no 11 go at the A and C no 27 at B no 12 at D

it is also posseble a diode inside the alternator is not good
take wire 568 loose from the altenator and try agian

I am betting on the Alternator. It was missing it's pulley when I bought it, so it must have been bad to begin with. !!

This really has my curiosity as you turn on the switch which energizes the coil/distributor, etc.You turn the switch off, opens the circuit up stops the electric/spark etc.Maybe I am repeating answer again, George(Svramselaar) is the man with the tech-know how.Bad switch?Pop the clutch with brake on to kill the engine?Then trouble shoot the wire in the distributor?Alternator?

[acudanut]

I am going to replace the Alternator. I will let you know the results. My gosh, these are not cheap.

hi

leave the alternator at the engine only loose the thin wire connector (568)
try again if the engine stops or not
if the engine stops the altenator has a bad diode inside it give`s power to the wire to the ignition if the engine runs contact off
be shure you have the wiring at the contact switch is correct see above
if you have the wire 568 loose and take the wire 12 from the contact switch engine wil not stop you have a short at the 12 wire or 568 to positive

let us know the solution

my guess ...switch...

Well, I have been watching to see how many guess's there were and there were a few, all good ones. But do NOT start throwing new parts at it to find the problem!!!!! That is expensive, wasteful, and will not always solve the problem. Mark had the best suggestion when he said to stall it with the clutch and diagnose from there. Start by removing the wire from the distributor so you do not cook the coil and also so you have a convenient point to check to see if you are still getting power to the distributor. As soon as you remove that wire check to see if it has power on it, it should if it was still running. If so go to the alternator and remove the small wire that George mentioned and check for power again. No power? then alternator is bad. If there is still power then there is nothing wrong with the alternator and you just saved yourself several hundred dollars! Pull the #12 wire off of the ignition switch and check for power, no power? Then the switch is probably bad. If there is still power then you will need to follow that wire from the distributor back and see where it is shorted to power but I will bet one of the two places mentioned is the problem. I lean towards the switch either bad or connected wrong.

Thanks guys. I will attack this problem asap. The switch was tested before I bought it, from a member here.!!

I have looked through the TM's and still think something is missing on the Alternator.
Did you notice my new freeze plugs?

Seems to me you have an extra wire on the alternator and they should be coming in from the end not the side. You should have #568 which is the field wire and is a small wire, #5 which is a heavy wire and goes to the main charging post in the alternator and #3 which is the ground which I see off to the side. But you have another medium sized wire in there that is not on the diagram, what number is that? The one with the blue on it?

Rick, that is wire #5 (paint code blue). Extra wire ? Not sure about that. Dang I hate electrical problems. On the far left of the pic, it looks like I am missing another connection. ???? I Thank you for your time. Salute !!!!
