electrical and charging

Trying to figure out a charging problem with my 75 yamaha xs650. Been following curley's guide and can't seem to figure out my problem. Also I have a aftermarket reg/rectifier combo that the previous owner put in. Curley's guide doesnt tell you how to check for that. So far my bike does not pass...

Hello and thanks for your time. I bought a 1980 xs650 and I want to know what would be cheaper route to complete the electrical/ignition. All I have is the wiring harness. I'm missing everything else electrical. I need to know what I'm missing and if I should upgrade the system. Thanks again

Ok, so i was having issues with my charging system on my 77 XS650. it had the seperate Reg and Rectifier with the adjustable Voltage Reg. i bought the bike it was not running, after many hours and $$ the bike ran and ran very well untill the battery would die, wires started to melt. the wire...

Stock alternator and 3-phase rectifier/VR-115 reg. With lights on and bike running I get 14.1 volts no problem. Bike runs and charges fine all day. But as soon as I flip the high-beam (new, clean aftermarket dimmer switch) my voltage drops to ~10V and seems to keep dropping :eek: Anyone...

I recently blew a Pamco ignition on my bike. I suspected the reason was the cheap reg/rec that comes with the PMA kit. Pete replaced my ignition under warranty no questions asked. Great guy and great product. I'll buy no other. My question is how would you check the field coils on the PMA...

Just saw an add in the horse. Morris magneto now made just for the xs650. Sposed to eliminate battery, coil and charging system. I assume only works with points setup. Anybody tried one or have experience running a mag on something else?

Hey everyone, I have a 1975 XS650. The battery will hold a charge for a short time. A lot longer when the bike is turned off and sitting. When I turn the key to "on" and take a reading on the battery I notice it drains by .10 every two seconds or so. That seems very fast. When the bike is...

Hello, New to posting here but been reading for a month and learned so much. I am fed up with the stock charging system that keeps failing and leaving me stranded. After reading a lot about the PMA on these forums I am thinking that is the most cost effective solution for me rather than to spend...

I'm working on an engine rebuild here and I have Hugh's PMA. Does anybody have experience removing the magnet from the crank? I know that it is a press fit but I don't want to bang it up in the removal process. Can you recommend a method or tools to accomplish this task? Jon
