Electronic ignition went KaPoot - IH 140


After two minutes running up my driveway the tractor shut off as if someone turned the key off. Spark from coil was little to none. Power to the coil was OK. Wouldn't even hint of firing while cranking. Changed coil; No help. Swapped electromic ignition from a 140 that ran good and voilla, fired right up and ran great under load (mowing) for an hour.

This bad ignition is 2 or 3 yrs old. I found out it wasn't seated properly after about 1 1/2 yrs. Maybe I damaged it somehow. The good one is just as old and seems fine. I'll order a new one and also get a spare.

I haven't seen any reliability threads for these ignitions and thought I'd provide a data point. Would like to hear from anyone else who has had a problem, or how long they function before failing.

Cheers
 
Every now and then I hear from a car guy with one that dies. No warning, and usually at least 50 miles from home. (Of course.)

They're sweet, but having a spare on hand is no bad idea - especially in an automobile application.

Terry: I told you so, first eletronic ignition I had go bad was a relatively new 1979 Oldsmobile 98 Regency, stopped dead on the road. Never had a distributor quit like that.
 
A lot of electronic ignitions release heat through correct mounting. I would check with the manufacturer and see if thermal grease should be applied to the device before mounting.
 
Just to clarify...is this the hall-effect sensor inside the distributor?

Or is there another "ignition module" in addition to the coil itself?

Just curious as I recently went thru an on-road rebuild on my pickup truck's ignition at 206k miles.
 

It's the little pick-up module that bolts inside the distributor and has two wires attached that go through the distributor to the coil.
