The maximum control circuit loss should not exceed 1.0 volt.
• If circuit loss does not exceed the maximum voltage allowed, and the switch is closed, the mag-
netic switch circuit test is complete.
• If circuit loss does not exceed the maximum voltage allowed, but the switch does not close, replace
the starter relay and repeat the above test.
• If circuit loss does exceed the maximum voltage allowed, continue on to next section.
Starter Relay Circuit Test (Continuation)
This continuation of the starter relay circuit test requires that the starter relay is connected and that a
low scale voltmeter is used. For best results use a digital voltmeter. The “S” lead should be disconnected
from the solenoid.
1. With the ignition rotary switch selected to IGNITION and the start button depressed, measure
the voltage loss in the following circuits. (If working from the engine compartment, flip the
IGNITION switch to the ON position and push the ENGINE START button on the Rear Run
Box.)
a. Solenoid “BAT” terminal to key switch.
b. Across the key switch.
c. Key switch to start button.
d. Across the button. Press and hold the button while connecting the meter.
e. Start button to the starter relay.
f. Starter relay to the starter ground. Maximum voltage loss in each circuit should not exceed
1.0 volt.
2. If any of the above circuit checks shows full battery voltage (when the start button is pressed)
then an open circuit exists in that portion of the circuit between the voltmeter connections.
3. Repair that portion of the circuit with excessive voltage loss.
4. Reconnect the “S” lead to the starter solenoid.
