I like the trail techs because they haven potentiometers... Even just the A/C regulators sans rectification.
I started this thread and I've posted a lot of stuff to it, I don't mind if you post here. This thread turned into an A/C tutorial for mopeds and I think a lot of people filled a lot of voids in their knowledge going through this thread.
I started this before I had any of my electrical courses in school, so it's great as an A/C tutorial for mopeds period.
Glad you figured it out, hope you come over to the DC side though! LEDs, halogens and electronics are super fun on mopeds!
