I'm working on this bike, i've got a single tapped (non electric start) 12v 80w tomos stator, hooked up to the 4 pin reg/rec out of a late model 2008 ish revival.
Based on this Regulator :
I breadboarded this last night using alligator clips and everything was hunky-dory, i had good light (looked to be regulating) on the LED headlight, and when i switched it backwards no light (polarity correct) so i sat down and made a super nice, tucked and wrapped wiring harness.
When i went to start it up the headlight was flickering, the tail lights were too bright, and after a couple seconds of runnign it blew the tail and brake light and now the LED headlight is just flashing.
I think i might have put too much draw on the Rectifier side of the unit, like maybe it can't handle full bore current into the center tapped 'dc' input? maybe it cant handle 12 or 6v x whatever current blows bulbs on the DC out? Maybe the reg/rec is fine and i'm a dummy?
Anyone mess with these? does this make sense? I was hoping using a known good r/r made in italy not china this thing would just fire up and work perfecto but maybe i'm using it wrong.
I'm having a really hard time finding any pure DC reg/rec units that aren't made for a floated ground. The only ones i find are this same center tapped coil style which makes me think maybe there is a reason and they can't handle the current on the 'battery' side. Maybe i should just take the 'floated ground' and ground one of the ac sides and send it? (edited)
