-KEY in POSITION 2 , you see the current State of Charge:
Voltage State of Charge
12.6+ 100%
12.5 90%
12.42 80%
12.32 70%
12.20 60%
12.06 50%
11.9 40%
11.75 30%
11.58 20%
11.31 10%
10.5 0%
(Battery should not have been charged or used for about one hour before this measurement)
-PREHEATING:
The voltage falls to about 10 volts.
-CRANKING:
The voltage falls to 6 /7 volts depending on temperature ...etc.
- IDLE and CRUISING: the voltage must be at last 14 volts even with lights, heater ..etc ON.
