Re: Battery voltage test
Typically, a 12V battery will read between 11.7-12.7 volts at rest. With engine running and no heavy loads turned on, voltage should read 13.7-14.2 volts. There will be slight variations depending on battery age, battery type, temperatures, etc., but anything close to these ranges would indicate a normal system.
An ignition off battery draw test would be the next test to do, but you need a meter that will read low current do do that. The test is to pull off one battery lead and put the low amperage meter between the battery and removed lead to read how much current is flowing with the ignition off. Anything over 100-200 milliamps would be suspect.
