54–01 Ground Cables
Checking and Cleaning
Check that the ground cables are clean, undamaged,
and tight. If needed, disconnect them, clean the mat-
ing surfaces with a soda solution, then connect them
securely. Spray the ground cable connections with
dielectric red enamel.
54–02 Battery Voltage
Checking
Check the battery open circuit voltage using an accu-
rate voltmeter. If the voltmeter registers 12.5V or
below, fully charge the battery to 12.65V. A fully
charged battery will have a voltage of 12.65V with
the charger disconnected.
