Testing Electrical Systems & components
TBolt USA Tech Database!

Testing seperate Electrical systems:

First Get a NEW Plug and test for Spark
See Video:

Make sure all electrical connections are tight and you have a solid ground from the engine to the frame.

Disconnect Kill button (will run/spark without it)

The coil is actually three parts 
coil
wire
cap
all three screw together like a wood screw , clockwise

Make sure you have a good spark plug (Pit bikes take the same plug as CRF50 & KLX110) 

Testing seperate Electrical Components

 STATOR:

1. (Once you have the ignition cover off) Visual test:  Inspect  the coil bar , if you see any bulges or discoloration its likley worn out
2. Voltage Meter will be set on AC for testing output
   The stator should have 80-100VAC (usually black/red)
3. Set meter to OHMs

OPEN circuit or infinity OHMs is bad

COIL:

1. Set meter to OHMs

OPEN circuit or infinity OHMs is bad
