TESTING
Voltage Regulator Bleed Test
1. Be sure regulator is connected to battery. Check BK
charging wire on gold terminal of master circuit breaker.
2. Locate voltage regulator connector [46] near the oil
pump. Disconnect from alternator stator wiring.
3. Check regulator connector using a trouble light.
a. Touch one probe to a suitable ground.
b. Touch the other to the regulator pins, one at a time.
c. If light glows, replace regulator.
Milliampere Draw Test
CAUTION
Make sure accessories are not wired so they stay on at
all times. This condition could drain battery completely if
vehicle is parked for a long time. Check for this by con-
necting ammeter between negative battery terminal and
battery.
1. See Figure 7-21. Connect ammeter between negative
battery terminal and battery. With this arrangement, you
will also pick up any regulator drain.
2. With ignition key switch turned to OFF and all lights and
accessories off, observe amperage reading.
a. Maximum reading should be 3 milliamperes.
b. A higher reading indicates excessive current draw.
Any accessories must be considered and checked
for excessive drain.
NOTE
A battery with a surface discharge condition could suffer a
static drain. Correct by cleaning battery case.
