VOLTAGE GAUGE
Figure 1. Battery Voltage Gauge - Step 2.
2.
Shutdown engine. (TM 5-3825-270-10)
CONDITION/INDICATION
Does BATTERY VOLTAGE gauge read 26 to 28 VDC with engine running?
DECISION
No - Go to step 6. (Step 6 - Are less than 200 ohms measured on red wire at alternator to positive terminal on
battery?)
Yes - Go to step 3. (Step 3 - Do batteries read 24.2 to 25.4 VDC with multimeter?)
STEP 3
Do batteries read 24.2 to 25.4 VDC with multimeter?

2.
Set multimeter to measure voltage.
NOTE
Water distributor is equipped with two 12-volt batteries connected in series. Multimeter
measurements must be made from correct battery terminals to obtain 24-volt measurements.
3.
