Battery Isolator
Posted a question two weeks ago about the possibility of running an inverter off of the battery isolator. Not such a good idea. I'll go to solar to keep my batteries topped off while I'm driving. Wh...

I agree with Buds statement. I have a small DIGITAL DC VOLTMETER panel meter I installed on my truck dash coming from the truck start battery terminals taht always read my truck battery voltage. I have noticed it reads DC VOLTAGEs that coincides with the standard DC VOLTAGEs of the typical RV converter/charger units... I usually see 14.2-14.5 VDC when I first start the truck engine and then this drops back to around 13.4-6 VDC and eventually down to 13.2VDC... When the truck motor is running I always see a 13V range on the dash meter. I see the dash meter change from 13.2-13.5-6 as I am using things I suppose... I occasionally see it jump to 14.4-5 VDC while driving down the road but usually goes right back to the 13V level.
When I turn off the ignition key then the DC Voltage drops down to 12.6-7 VDC... If I turn on my truck lights with the motor not running I usually see a 12.3-4 VDC reading...
I have never seen real high DC voltages in the 15VDC range coming from my alternator on my 2010 Truck DC Meter setup... Perhaps I will look at it more closely now that the question has been brought up...
The main reason I installed my dash mounted DC VOLTMETER was to watch the truck start battery readings when I am using my Ham radio two way radios without the motor running. When it drops back to around 12.0VDC I will either run my truck motor or start up my 2KW generator with a battery charger plugged into it...
Maybe the different truck manufacturers do it differently...
