Why does my alternator not charge the batteries?
Why does my alternator not charge the batteries?
Allows alternator to charge both battery banks, but separates the battery banks when the engine is off so that the house batteries do not discharge the chassis batteries. If so, a failed relay or wire from alternator to relay would keep the alternator from charging either battery bank.
What should I do if my battery won’t charge?
Make sure the inverter/charger’s breakers (on the 120 VAC breaker panel) are on. Make sure the resettable breaker on the inverter/charger (some inverters have them external, some internal) is ON/RESET. Next, before plugging into shore power, measure voltage at the house battery with a digital voltmeter.
Is it possible for a battery to go bad?
Do not give up on the batteries being bad. You could have one cell that is going bad and it will draw the rest of the battery down but total voltage may show good. Use a hydrometer and check each cell. They should be within specifications for that battery, and they should all be very, very close to the same reading.
How do you charge batteries in a coach?
And some coaches have both battery banks wired so they are charged by the inverter/charger, others are wired so that only the house batteries are charged by the inverter/charger. If the latter, you will need a trick l start, Echo charger, etc to charge the chassis batteries.

What’s the battery voltage on a Ford PowerStroke?
Battery voltage was 12.62V, dropped to 12.52 volts after about 5 minutes of idling. I took it to Ford (still in warranty) and they said it was a “bad connection under the motor”.
