Battery Source Test
- With all coil wires connected, connect a voltmeter between coil battery terminal and ground. Using a jumper wire, connect coil "DEC" terminal to ground. Ensure all lights and accessories are off. Turn on ignition. Reading should be 4.9-7.9 volts.
- If voltage reading is less than 4.9 volts, check primary wiring and resistance wire for damage and repair (if necessary). If voltage is greater than 7.9 volts, replace resistance wire and retest.
