Ignition and Pamco Question

[CD15]

Hi All,

I'm slowly working on my '83 XS650 and ran into an issue with the Pamco Ignition today. I'm still new to this system and my new bike, but during troubleshooting, I noticed the ignition started to smoke (not sure how yet). I ended up cutting the resistor from the wiring to inspect it more closely. Now I'm wondering if that was a mistake—can I resolder the three wires, or will I need to replace the resistor? If so, is it possible to get a replacement directly from Pamco?

I haven't been able to kick over to start it (no starter, going to source one) this is why the electrical trouble shooting. Old owner replaced the wiring with the right parts but I know batter seems to be dead and need a new one. I also think there might be a draw somewhere potentially. I read somewhere that the 83 has a kickstand switch so you aren't able to start it without disengaging? Mind you this bike is no longer stock so not sure if they disengaged it.

Also, are there any other ignition systems that are plug-and-play for the '83 XS650 and might offer better reliability, or is the Pamco still a good system to stick with?

PAMCO is out of production. If you have let the smoke out of the ignition, it's very likely toast. Unfortunately I think you're looking for a new ignition system.

Thanks it's been a long time, that's what I thought as well, most likely cooked now. Mind you it shows no visible sign of damage.

What is recommended for my model year for a new Ignition. I have read about Raw Hide, Tytronic...is there anything else one recommends?

Does the bike have the stock alternator with the TCI pick up fitted?

I don't think it's a stock alternator, but for visual understanding can you send me some photos of what I should be looking for?

OK. If you don't have the stock alternator fitted then using the Yamaha TCI isn't an option open to you unless you refit the standard alternator back on.

Acquire a Factory Service Manual for XS650SJ. I’m sure there is a download available. It will show you all of the stock components and wiring.

Quick question guys but do I have a single phase or double phase. I think the resistor is pooched on my Pamco and I am looking at the Tytronic option eBay but not sure which to purchase. I have attached photos of the Pamco set up I had and the two Tytronic options I'm looking at for (83xs 650). Thanks in advance for the help.

Are you running one ignition coil with a waste spark or two coils?

 

[CD15]

See attached, not entirely sure.

You appear to have one dual output coil (one coil with two plug wires). That's what the Pamco used.

Thanks 5twins for the response, so that being said would I purchase the first pic or the second pic? Which is best for my current set up.

For the dual output coil you need the single pick-up.

Fantastic, thank you for the assistance!
