Ignition System Check

Check battery voltage for at least 11.5 volts. If less than 11.5 volts, charge battery. If more than 11.5 volts, attach voltmeter positive lead to coil positive terminal and negative lead to ground. Voltage should be within 1 volt of battery voltage.
If incorrect reading is obtained, check wiring between coil positive terminal and ignition switch. If voltage was within 1 volt of battery voltage, attach positive voltmeter lead to coil negative terminal and negative lead to ground. Voltage reading should be more than 2 volts.
If voltage is incorrect, disconnect wire leading to control module (amplifier) at coil negative terminal. Again check voltage at coil negative terminal. If less that 2 volts, replace ignition coil. If more than 2 volts, replace control module.
If voltage in step 2 was correct (more than 2 volts), disconnect control module from distributor. Turn ignition switch "OFF" and attach leads of an ohmmeter (set to high scale) to distributor pick-up coil leads. Resistance reading should be 2200-4800 ohms. If not, replace pick-up coil.
If pick-up coil resistance is correct, connect control module to distributor. Attach voltmeter positive lead to coil negative terminal and negative lead to ground. Measure voltage. Then crank engine and voltage should fall. If not, replace control module.
If voltage fell in step 5, but system still is not operating properly, check high tension wires, ignition coil secondary, rotor arms, distributor cap and spark plugs.
