The "key on" voltage check won't tell you much because the normal RUN circuit is shut off during the start cycle.

On your ballast you will find a double blue wire on one side and a blue/brown on the opposite side. The double blue should have battery voltage only when the key is in the RUN position and the blue/brown should have battery voltage only when the key is in the START position.



This is different then what I just read from the other posters. So, how do I go about checking the ballast? Just see if voltage exists on the double blue wire side when key is on RUN position...and then verify voltage on the blue/brown wire side with key in START position?

I am getting confused again...
