EnDuraSpark Electronic Ignition

Installation & Troubleshooting v5.1

Troubleshooting - No Spark (continued)

Check the Ignition Wires and Caps

Leaving the spark plug caps attached to their ignition wires, measure the resistance end-

to-end of the wire/spark plug cap combination. It should be 1K or 5K (depending on the

spark plug caps were used. Early Airheads had 1K Beru caps; many users have replaced

them with 5K NGK caps.). Test all wires and caps. A meaurement over 5K indicates a

bad wire or spark plug cap. In that case, remove the cap from the wire and measure the

cap and wire independently. The wire should be 1-2 ohms and the cap 1K or 5K ohms.

Replace Spark Plug(s)

If the coils, ignition wires and caps check out okay but there still is no spark when the

trigger terminal is grounded, the problem must be the plugs. Replace.

From this point forward, it is assumed that the ignition system passed the “Check Secondary

Coil Circuit” test described on the previous page.

Check Timing Wheel

Remove the front engine cover exposing the trigger unit. Grasp the timing wheel and

verify that it is slipping on its hub. If so, the set screws have become loose. Follow the

procedures for setting the EnDuraLast Electronic Ignition timing.
