Hi all, new to XS650s, but I have some experience with motorcycles in general. Long story short, bought a 650 with HHB’s Pma system installed, kickstart only, no battery, sparx capacitor. Bike worked great when I went to check it out, I rode it home no problem. Next day I go to start it and nothing. Checked I had the key in the right position, gas is flowing, check for spark and now nothing. Is there a common failure point in these systems? I checked all the wiring connections, fuses, and the circuit board of the pma and it all looked ok. Any thoughts?
 
Try hooking a battery up to it and see if it cranks. Caps age pretty quickly in this application.
Edit Ignore what I just said. Went back and read first post and realized it was a HHB DCCD.
Check grounds on coil and cdi box and relay for kill switch.I
 
I seem to remember someone mentioning discount the blue wire from the relay to defeat the kill switch.
IIRC because a cdi has to be grounded out to stop the spark HHB uses the kill sw to send 12v to the control pin of a relay that when energized unshorts the cdi coil output.

Both 3.2 Lb's, the stock is an inner rotor and the Vape is an outer one. I ran in that situation this summer,had a wire from the regulator break (my fault) which killed the battery, pulled the blue kill switch wire and bike fired right up was good to go.

Looks like it's the vape that uses the blue wire. So you need to find the relay that kills the spark and pull the grounding wire to test if the relay is not working. I don't have a schematic of Hughs system.
 
Blowing out Pamcos (ignitions) on cap only, PMA bikes is a "thing"
Terms; the charging system is a PMA, the ignition is one of several electronic ignitions that may have been fitted. Pamco and several replacements now that Pete quit are all sensitive to voltage spikes. Hint you need to keep some load on the system to prevent voltage spikes. An incandescent headlight is one good way to provide this "voltage damping" but a battery is the gold standard for damping high voltage that kills electronics. Many PMA systems also came with cheap um "asian" voltage regulators that tend to fail in "full charge, full time" mode, which also kills with high voltage. Troubleshooting is what will be needed.
 
OK, So I am in the same predicament. And yes, I NEED some help. I had previously owned a 1978 Yamaha XS650E - brand new... And now own a 1983 650... I understand the ignition system had changed in 1980 thru 1983. I bought the bike knowing it was "partially" a project bike and it runs great except doesn't charge. So it looks to me as if it has the newer rotor/stator assembly, but it doesn't look like the "cam" portion of the change out has been completed. I don't see a capacitor anywhere but I do see the newer regulator behind the motor. The starter was also removed (but I have it) so I suspect it was to be set up for operation WITHOUT battery.

What steps, or "parts" would I need to have the change over COMPLETED?

Anyone?
Anyone?

Please help!

How about we see pics of the LH with the cover off?

To clarify the cover Gary is referring to is the chrome cover with 2 screws near the top of the engine.
I not sure if Hugh sold Pamcos to go with his original PMA systems. His newer system is a cdi triggered on the flywheel.
Pics with the cover off will give us a better idea of which ignition you have.

lower "alternator cover" also.
 
He seems pretty sure that he has a PMA so I wasn't figuring to learn a lot under the alternator cover.

The reason I ask is because that is a Pamco style ignition and from what I understand they are somewhat intolerant to low battery voltage. Or high voltage for that matter.
 
I also noticed, the part directly UNDER the battery cover (maybe an old regulator?) is not connected to anything.
