"I`m running 12V conversion, so Power ain`t the problem, I don`t think?" Wrong assumption. A 12V switch over job means nothing as far as power is concerned. Many of us with original 6V/POS GRN systems have no problems starting right up even in sub freezing temps. Why? Because we maintain them properly. Whether 6V or 12V you must maintain a battery that will sustain a charge under load. A starter zinging sounds like the battery is going dead or already dead. How old is it and is it the correct 12V GRP-25 or GRP-35 type? Take it to your local trusty starter/alternator shop and get it bench tested on their equipment to verify condition. If it checks bad, replace with a decent brand (INTERSTATE, DEKA, EXIDE), not a cheap Wally World type -poor to non-existent life spans. How did you 'test' and 'lube' the starter Bendix? Did you perform a motoring test? While battery is in the shop getting tested, go thru the entire wiring system to verify it is correct. See "WIRING PICTOGRAMS by JMOR" in our How To's. Find your set up and thoroughly check each wire by continuity, not by a visual 'color code' inspection. Do not deviate from the set up in PICTOGRAMS. If it doesn't match exactly, it ain't right so don't make another popular assumption that skipping a step or leaving out a part (or adding) is OK. Chances are your wiring is jazzed up too. Determine the root cause of the problem and fix it,then report back.
