I get the impression you know a lot about electricity, I'm a hack, but I try to understand as much as I can. In that thread that we were slamming "ollie" for being a clown, some good stuff came up, I wasn't sure if you missed it, or just had no response.
Here's a link to the thread:
It's that one where we were talking about AC or DC, and I tried to make a general explanation about how a moped generated power, and what was happening--I also had some questions.
I think there's some important ideas, we should address, because "electrical" is one of those areas that can cause people so much trouble when trying to repair an old bike--- If we understand more about the individual parts, and what part they play in the larger system, we will be able to troubleshoot and fix more easily.
Anyway, check out that thread, or I can clip and paste it-- I was also asking Ree about if a TOMOS was AC or DC---
And everyone else-- Post questions or information about how the electrical system on your moped works-- Winter's coming, we ought to get some good information circulating (along with some heat....)
