Hi all,
I've just finished installing a home-spun RD350-based PMA. I believe it's the same rotor and stator as the US Banshee. It uses a 5 wire three-phase reg/reg with 3 yellow wires, a red and a black. The three yellow wires are connected to the three wires from the stator, the the black wire to ground and the red wire to battery +ve.
After installing the PMA the bike will start and run but won't really idle and the throttle needs to be very gently applied or the bike will cut out. It sort of splutters at low revs if you try to snap the throttle. At higher revs it sounds like it's running fine. I've briefly tested it with a voltmeter and it makes about 12.5 volts at idle and about 13.5 at 3000 rpm.
To confirm, the bike ran fine before I swapped the charging system. Whilst the source of the problem could be a huge range of things I tend to blame the last thing I did.
My main question is; in simple terms how can the PMA be eliminated from the fault diagnosis? I'd like to run the bike in some kind total loss form to test whether the PMA is the problem. I've read a few references to doing it but none were specific as to what should be removed and what shouldn't.
Any help greatly appreciated.
