December 29th - Dizzy Cap Failure

I planned on taking the Jeep and Dodge out on the 30th, to get some photos of the new Dodge crane. The day before, I wanted to run them both to make sure all was well. The Dodge started fine, the Jeep didn't show any signs of firing and when it eventually did, ran rough. I felt there was something wrong on the last day of the Beamish show in September, but got home without problems.

After the rough start, I cleaned all the contacts on the plug leads, then removed the dizzy cap. When I did, I found the end of the brush flush with the cap and jammed. To get the Jeep to run at all, it must have been arcing from the carbon brush to the rotor arm and soot on the rotor arm seemed to confirm this. This "Joe's Motor Pool" part was only fitted in April 2021 and has only done a little over 200 miles since fitting.

I pulled the old dizzy cap from the locker and fitted it, after which, the Jeep started up straight away. I found a replacement brush and spring on Ebay, so hope to be able to bring the "JMP" back to life.
