- on resting battery, from 12 V to 10 V
- on charging battery, from 13 V to 11 V
- on alternator, from 14 V to 12 V.
- Digital multi-meter connected straight to battery shows the correct voltage
A fully charged resting Bat should read 12.7V that is after it has sat for an hour or so off the charger. Once motor has reved above 1500 RPM the ALT should show 14.5V
