Light coil

[Pete57]

is there any way to check the light coil in a wico without the engine running? Lights were working until I bumped a wire. Turns out that the light wire coming out of the magneto had been bare in the one spot were I moved it. I am wondering if it grounded out and ruined the coil. I put a volt meter on the wire with engine running and couldn't get a reading. Thanks, Pete

Hi there     the light coil wire should be grounded on one end under the flywheel and with the engine running , should be about 2 - to 8 volts A_C current , depending how fast the engine goes ,, be sure to put meter on the a-c  mode , if you pull the flywheel then it should be that old orange wire color and not look ( or smell) burnt    best wishes    Larry.

Fixed the wiring coming out from the coil, started her up and got a good reading. Connected the wires for the head light and brake light and it quit working. Time to replace wires to head light and brake light next. Thanks for the help! Pete
