Wiring Diagram Help Needed Suzuki TC100

brewsky · Post by **brewsky** » Thu Jul 01, 2010 5:41 pm

Don't know if this is proper place to ask, but here goes anyway.
Working on a TC100 Suzuki 2 stroke enduro for a neighbor, trying to sort out some electrical issues.
Here is a post from another forum, but I didn't get any answers that made sense to me. I'm sure someone here can set me straight.
Any help appreciated!

"Attached is the only wiring diagram I can locate for the bike I'm working on, a 1975 TC100.
The diagram shows the one magneto winding going directly to the ignition coil and also grounded by the ignition switch in off position.
The parts fiche show a rectifier and voltage regulator but this diagram shows only a resistor and single diode, neither of which is in the ignition coil circuit.
What am I missing?
Doesn't the Magneto put out ac which needs to be rectified before it goes to the coil?"

Not if it is an ac coil. Back in the day, we used to strip everthing off of our Enduros, and have just one wire from the magneto to the coil.

Never knew there was such a thing.
I thought the generic wiring diagram was screwed up, but that would explain it.
The old Yamaha RT I was working on had ac for lights and dc for ignition, battery, and turn signals.
What's the difference in the ac and dc coils?
Thanks

Not sure what the difference in the coils is. I'm working on an RT1 for a guy right now, trying to straighten out butchered wiring, missing rectifier and horn, disassembled bar switch etc. Do you happen to have a good wiring diagram for the RT1? An extra left bar switch?

No extra switch, but a couple of diagrams..not exactly "good" but all I could find.

Found a parts manual also if you need one. PDF file.
Don't know how to attach it, but could e-mail if you need it.

Brewsky, thanks for the diagram! I've been using the online microfiche for a parts manual. Can you yell me where the rectifier and horn mount?
