It has been working just fine until today. For some reason it will not start unless we pull the coil wire and just hold it far enough from the coil so that a spark jumps from the coil to the wire. It starts and runs just fine this way. We put the wire on the coil just far enough that it jumped the spark and used the tractor for several hours this way. If we push the wire all the way in the coil the engine stops. We tried two different coils. The wires are new, we tried a different coil wire, and we changed the points and condenser. Nothing changed it still will not run unless the coil wire is jumping a spark. Any IDEAS??? Thanks for any help. [Reply]   [No Email]

I know some people will swear by them but I only swear at them.   [Reply]   [No Email]

It had a little mark on the topside just under the center tab. When I turned it over I could see a small mark that it must have been arching through. It only had a few hours on it but apparently it must have had a flaw in it. Thanks to everyone for their advise. I really appreciated it.   [Reply]   [No Email]

I know!!!!!! But try it anyway.   [Reply]   [Send Email]

Dean 11-07-2009 16:34:56 67.172.13.37 456388 Report to Moderator	Re: Very ODD 12volt jubilee problem in reply to Joe J., 11-07-2009 16:10:28   Though it would be odd, for all 4 to so fail at the same time, failed/fouled plugs can cause such symptoms. The long gap that the spark must jump causes the induced voltage to increase much higher than normal, which can produce a spark across the gap of a plug that would not fire at normal secondary voltage. Have you changed the plugs? Are the wires copper core or TVRS? Dean   [Reply]   [No Email]

He did chock out the tractor when the problem started. The odd thing is that we plowed with the tractor this afternoon for several hours and it still would stop if we pushed the coil wire in. So I don't think its the plugs but I will take a look at them in the morning. Thanks Dean.   [Reply]   [No Email]

I will pull the plugs in the morning and maybe even put the old ones back in just to see if it helps. Thanks Al.   [Reply]   [No Email]
