 Battery voltage
My 60 Frontenac (Falcon with some Maple Leafs) stalled the other day. Battery didn't seem to be putting out enough power to crank well. I tested the battery and received these readings:
Turned off: 12.8 volts
Idling without accessories on: 12.5 - 12.7 volts
Idling with lights and radio on: 12.4 volts
The shop manual refers to test voltages between 9 and 10 volts. So, before I buy an ammeter to test the generator, I am wondering whether such readings are common and acceptable.
The readings kept dropping on the last two tests, maybe because the generator wasn't charging the battery while idling.
