Just a couple of additional facts....

Suzuki XR 400
Model: SM 21
Body #: SM 21 10843

Engine: SM 20
Engine #: SM 20 18804

Not sure on the year.......'70's or 80's


Also on the plug that the coils plug into there are 3 wires, of which only one is hot!



Thanks for all the help!

Umm, one is HOT?? As in 12v + ??

If so, you have an "automotive style" ignition. DC current to the coil and negative-triggered from points/CDI... Opposite of magneto/motorcycle/jetski/outboard style of coil.

Therefore, you can use two LAWNMOWER coils...

If you can get your hands on a schematic (maybe from the dealer) then scan it and post it...

WOW!

That's CHEAP!

To be honest, that is not the one that is in the sled now, but the one that is there, is not the original. I need to find a location that I can take the serial #'s to & find out the year, then I believe problem solved. For that price, I may just buy and and see if that will work. Thank you for all of the help!!!!
