Ok so im trying to figure out what's going on...have a 78 with pamco and hhb pma..been fine for 5 years..coming home from work bike started dying and backfiring..had battery tested and they said it was dead would not charge..so bought new battery..rode for a week fine..then did the same thing...i tested battery and its about 12.5. the bike starts but will not idle unless I give it gas..if I let go it dies...i tried giving it gas and testing voltage with revs im only getting high 12's ..i been trying to browse threads on this already but I'm trying to figure out how to test reg/rec...my voltmeter skills are limited but am willing to try with some guidance.
