Solenoid Testing: Insulated Base Remote Solenoids

Step 1: Check the voltage on the battery side of the solenoid as
shown on the left. The reading should be the same as the battery
reading (12.6V = Full Charged Battery).
Step 2: With the voltmeter still connected, activate the switch and
read the voltage. The voltage should not drop below 10.0 volts on
this terminal. If the voltage drops below 10.0 volts, the battery
cable should be cleaned or replaced. If the reading is 10.0 volts or
more move on to step 3.
Step 3: Keep the negative voltmeter lead on the ground terminal
of the solenoid and move the positive voltmeter lead to the
terminal marked “S” on the solenoid. Activate the switch and
read the voltage. The Voltage could read a little lower than the
previous reading but should never be below 10.0 volts. If the
voltage is lower than 10.0 volts, you must troubleshoot the switch
circuit (toggle switch, push button switch, or voltage supply to
these switches).
Step 4: Move the positive voltmeter lead to the battery terminal
on the solenoid and the negative voltmeter lead to the terminal
that the starter cable is attached. Activate the switch and read
the voltage. The voltage should read no more than .3 volts. If
the reading is more than .3 volts the contacts have excessive
resistance and the solenoid be replaced.

NOTE: Before Performing These Tests You Must Fully Charge and Load Test The Battery to Verify It Is Good.
