Yamaha G1 & G3 Golf Cart Source Coil Stator Replaces 8G8-85511-20-00

New Source Coil that fits Yamaha G1 & G3 2-stroke gas golf carts.  The wire colors match the harness colors, and plugs in with absolutely no cutting or splicing.  This is a custom wound source coil to replace the obsolete Yamaha part number 8G8-85511-20-00 found on all gas G1 & G3 models (1979-1989).  Made in USA with domestic and imported components.  Basic instructions are included in package.

Testing your source coil is fairly straightforward.  First find the magneto wire bullet connectors underneath & in front of the air filter.  Unplug the brown wire & connect the red lead of your multimeter to the brown wire leading into the engine.  Connect the black lead of your multimeter to a metal piece of the engine, such as the crankcase.  Set your multimeter to resistance (Ω).  You should see about 350 Ω at room temperature.  Readings between 300Ω and 400Ω are generally fine.  Now set your multimeter to A/C Voltage and crank the engine.  You should see about 50 to 60 volts at a steady cranking speed.  If your readings aren't similar to these, you may have a bad source coil or faulty wiring.
