3.INSPECT AUXILIARY BATTERY VOLTAGE
3.INSPECT AUXILIARY BATTERY VOLTAGE
a.

Measure the auxiliary battery voltage with the ignition switch off.

Standard voltage:

11 to 14 V


HINT:
·

A simple method to determine whether the auxiliary battery is discharged is to operate the horn.

·

If the voltage is below 11 V, recharge or replace the auxiliary battery before proceeding.




b.

Check the fuses and relays.


c.

Check the connector connections and terminals to make sure that there are no abnormalities such as loose connections, deformation, etc.
