Protection fuse 10A 250V
Contact breaker point condition
Connect the black wire to the distributor ground.
Connect the red wire to the moving part of the CB points or the primary output wire.
Switch on the ignition making sure that the CB points are closed. The display shows
a value in volts. Below 250mV a continuous audible sound is emitted. If the audible
signal stops the CB points are in poor condition.
