EnDuraSpark Electronic Ignition

Installation & Troubleshooting v5.1

Troubleshooting - No Spark (continued)

Check Secondary Coil Circuit

Remove a spark plug and

securely ground the plug

threads to a cylinder fin.

Position the plug so that it can

be seen firing.

Disconnect the black trigger

wire on the right coil which

goes to the EnDuraSpark black

box. Using a 2’ wire with clip

leads, clip one end to this

terminal. Turn on the ignition

and touch the other end of the

wire to a cylinder head fin.

Every time you make/break this connection, you should see the spark plug fire. This is

what the points used to do: make and break a connection to ground. Repeat for the other

spark plug (or other three spark plugs for dual-plugged engines) and verify that each

spark plug “sparks”. If they do, the coils, plugs, wires, and spark plug caps are okay. Skip

to the “Check Timing Wheel” procedure.

Check Primary Coil Circuit

If there is no visible spark at the spark plugs, investigate the coils further. Leave the 2’

wire in place (connecting the outer male terminal on the right ignition coil to ground) and

connect a voltmeter positive probe to an inside spade terminal of either coil. The voltage

should read about 6.5V, half the voltage of the green/blue wire. (After this test remove

the wire with clip leads so we don’t burn up the coils). If not, the coil is bad (bad primary

circuit) or the crimp connections on the jumper wire between coils are loose.

Check the Coils

Disconnect all the wires connected to the coils, including the high tension lead. With a

multimeter on the ohms scale, measure the resistance between the two spade terminals

on each coil. They should measure 2.0 - 3.5 ohms, the primary resistance of the coil. If

outside this range, the coil is bad or you are using the wrong coils.

Measure the resistance from each high tension coil tower to either of the male spade

connectors. This secondary resistance will be 12-17K ohms for stock Bosch coils, 11.5K

ohms for Accel 140403S coils, and 14K ohms for Dyna DC2-1 coils. If any of these

measurements are open circuit, short circuit, or too high resistance the coil is bad.
