Default Re: Spark Question

Ignition on, points open, should have battery voltage on the points arm. Points closed should be 0 Volts. If timed correctly this means your ignition primary circuit should fuction (switch, wiring, coil ).

Ignition off, then take a lead off a spark plug and space the lead about 1/8 inch from the plug terminal, ignition on, use the starter rod in the mmotor bay to engage the starter and you should see a spark across the lead to plug gap.
