What’s the voltage regulator on my Silverado truck?
The truck now has 85,000 miles and on my way to go camping (about 125 mile trip one way) the voltage regulator dropped to around 11 or 12. Of course I panicked and found the nearest parts store to check for a bad alternator, they said all good no problems.
What’s the voltage of the battery on a Silverado?
As long as you don’t drop the battery below 11.3 volts — where the inverter automatically turns off due to low voltage, you will have constant 120 volt output. As the isolator does not kick in until the alternator is spinning, there is no voltage drop when the engine is cranking.
Can a Silverado start with a dead battery?
There is no danger of a dead starting battery as the second battery is disconnected from starting battery when the truck is off. Once the truck is turned on, the isolator relay reconnects the second battery to the alternator.
