How long do you run an engine to charge the battery?
Remember: After you’ve done a jump start, you’ll need to keep the vehicle’s engine running for around 30 minutes to allow the alternator time to charge the battery sufficiently.
How can I tell if my house battery is charging?
Both of these systems charge the battery, you can check the voltage at both sets of batteries and if they are both getting a charge then they are connected through the switch. Typically only the house batteries get a charge when plugged in so if both are getting a charge, the switch is connecting them.
What to do if there is no charge on the House Battery?
If there is no charge, you may have an issue with a momentary switch, a solenoid designed to allow a charge from the alternator and a jump from the house batteries to the engine battery by a switch usually located on the dash. Use your multimeter on the alternator side of this switch to verify a charge from the engine alternator.
How do you test the charge of a battery?
To verify there is no charge coming to the batteries, first test the charge at the house batteries with a multimeter starting with the unit unplugged to test the current state of charge on the batteries, then plug the unit into an outside electrical source or turn on the genset and see if the charge changes.
Where does the alternator charge the house batteries?
As for the alternator, it should charge both chassis and house batteries when the engine is running. Since both systems are usually isolated from each other, there is usually a solenoid switch that connects the batteries when the engine is running. It is usually a can in the engine compartment.

What’s the best way to charge a car battery?
Also, you may find that charging your battery takes longer while your running appliances off of it. In fact, if you run too many appliances, you may find that your battery doesn’t receive enough power to charge at all. One of the most popular ways of charging a 12-volt battery is by using a vehicle’s alternator.
