Voltage Failure
1. Check battery and alternator
cable connections for loose
connections and corrosion.
Tighten battery connections and
clean
battery
terminals
as
required.
2. Turn ignition switch to OFF
position and measure battery
voltage from positive (+)
terminal to negative (-)
terminal. Voltage should be at
least 12V. Check each battery
in system.
If voltage is not as required,
charge or replace battery (WP
0107 00).
+12V = STATIC
+6V = START
