Reply to "Postwar 2356 F3 - Can't Eliminate Excessive Collector Sparking"

bmoran4OGR Forum Member

I just replaced the whole pick up assembly. This did not reduce the sparkling. That rules out a collector issue. I then unsoldered and resoldered every connection. Additionally, I cleaned the e-unit fingers and drum with CRC 2-26. I also removed the brush plates again and did another pass at cleaning the commutators, brush wells and such to no avail. No change in sparkling. Very frustrating as this isn't the typical occasional sparking, but constant impressive sparking.
