CDI Output Test
Using Peak Reading Adaptor
Re-connect all wires to the CDI box. Disconnect the white/blue
(WH/DB) CDI output wire from ignition coil primary terminal.
Install the Peak Reading Adaptor (PV-39991) to your meter and
connect one meter lead to engine ground and the other to the
(WH/DB) CDI Output wire at the ignition coil. Set meter to read
DC Volts. Crank engine and verify CDI output to the ignition
coil. When finished, reconnect CDI output wire to ignition coil.

Pulser Coil Output / Resistance Tests

Disconnect the 4-wire connector at the CDI box. Install the Peak
Reading Adaptor (PV-39991) to your meter and connect one
meter lead to the dark blue / black wire (DB/BK) and the other
to engine ground. Set meter to read DC Volts. Crank engine and
verify pulser coil output.
