40c Ignition problems
Is anyone else experiencing problems with condensers? Drove crawler out of the garage and parked it a couple of months ago. Now won't start. Power to distributor but no fire at the points. The coil is relatively new and I did replace points and condenser a few years ago with aftermarket parts now supplied by John Deere. My son in law had the same problem with his MT and traced it down to a bad condenser. He replaced with the same aftermarket one that I used and it only ran for a day before it failed and he had to put another condenser in.. I suspect that my condenser is bad so I will replace it and the points tomorrow. Are there any condensers on the market that are reliable or is it just a crap shoot? What would you recommend? What about an electronic ignition module. Are they available for the original 6 volt system or would I have to change over to 12 volt?

Re: 40c Ignition problems
I have been having the same problem with condensers. Mis firing simulating a lean running engine when starting to and a work load, hard starting, no start etc.
I have not found a reliable new source. I have been using NOS OEM from Deere with Green and Black 4 legged Deeres. I have used the 12 volt negative ground electronic ignitions with great success.
Best regards, Bruce

I stock quality ignition parts for the 2 cylinders. I'm pretty sure I know what Deere sold you, and they are junk. I got an order of them in years ago, threw them all in the trash.

Re: 40c Ignition problems
Just wanted to give a nod to Lavoy and a thanks for supplying quality ignition parts at a reasonable price. Picked up mine, points, condenser, rotor and dist. cap, from the shipping depot on the weekend. Quality parts made on this side of the pond, fit well and the machine started up, which it wouldn't do before. Think my problem was the crappy condenser supplied by JD but I replaced everything since all of my parts came from the same source in the same time frame. My son-in-law had the same problem with a Deere supplied condenser in his M. Thanks Lavoy.

Re: 40c Ignition problems
Glad to hear it worked. What you experienced is why I quit using all of the cheap ignition parts, just too frustrating.

Re: 40c Ignition problems
I tried to test the old condenser that wasn't working (previously sourced from JD) and the lead wire fell out. Didn't look burnt, just disconnected.

Re: 40c Ignition problems
I have read a page on the Internet that accuses condenser manufacturers of not making a good connection to the rolled up foil inside when sealing up the ends of the can.
If you have an ohmmeter it may have a capacitance test function. This can be used to check condensers before you waste your time with them. (Condenser needs to be off the machine.)
