Saw mention of the Delco transistor ignition option in my 656 I&T manual. I don't remember mention of it in the operators manual. I was wondering about its lack of popularity and googled it. Seems moisture intrusion and heat were detrimental to it when used in the GM cars from the factory. Heat and water are 2 things a tractor gets a lot of--so likely even more problematic than in a car! also the germanium transistors used were not as good as today's electronic components.
This is not HEI, but an earlier attempt at high voltage ignition. It was stock in some cars around 64-70.
Has anyone been around a tractor with the Delco transistor ignition? How long til it got thrown in the junk and replaced by a regular points distributor?
