I bought my 1980 P200e a few months ago. It's got a 12v electrical system, but it's a real mess. The battery is literally held in with a bungee and some duct tape. The bracket to mount the spare tire is completely missing.
The diagrams I see in the manuals are nice, but I'd love to see what other people's battery and wiring look like, so I know what I should be shooting for as I clean mine up.
So, if you've got a moment, please take a picture of your P200e battery and wiring under the left cowl, and let me see!
Thanks so much!
