TESTING

1. Disconnect the choke lead from the voltage regulator.
2. Connect an ohmmeter between the lead that you just disconnected and a good ground. The ohmmeter should read about 9 ohms.
3. Replace the choke cap if the reading shows an opened (no resistance) or shorted (infinite resistance) heating coil.
4. If the choke coil is working properly, but a fault is suspected in the choke heater system, substitute a new voltage regulator to see if it will solve the problem.
