I had 2 RDs with similar issues. As a teenager I wasn’t smart enough to test for all the possibilities — I was too busy trying to short-circuit the process so i could get back on the lake.
I never bothered to check the coils — didn’t figure it out until I was in my early twenties and all my 950s-70s were failing… the coils had fine cracks in them and as an engine started to warm up, the coils expanded and windings were separating. Leaving a motor to cool for about an hour would allow the coils to shrink so I could start the whole process again.
