Distributor/Hall Effect Sender

  1. Remove coil secondary and attach to ground. Disconnect Hall Effect sender wire at the distributor. Using a LED Test Light (US 1115), check for voltage between outer terminals of connector. See Figure or Figure . With ignition on, light should be on. If not, check wiring for short or open circuit. If wiring is okay, replace Digifant control unit.
  2. If light came on in step 1), reconnect Hall Effect sender harness connector. Pull back Hall Effect sender boot to expose contact terminals. Apply LED Test Light (US 1115) probe to center contact and battery positive terminal. See Figure . Observe test light while cranking engine. If test light blinks, Hall Effect sender is okay. If not, replace Hall Effect-sender.
