Chassis battery help

Yahoo Message Number: 112105

Drove 300 plus miles today. Shut down coach to check in for the night. Would not restart. No juice. Acts like a dead battery. Boost switch works great. Started coach from house batteries. Chassis battery is only one month old. Is there a breaker in the line somewhere.

Check chassis battery for loose connection.

I agree with John. 17 years ago we were driving my Dad's 2000 Magna and we stopped for lunch with the kids and the coach died dead as a stone. Coach has

Assume you will check all your battery connections.

Since you could start the engine by using the boost solenoid switch the problem is not your boost solenoid but it may not be getting activated when the engine is running.

One way to check the boost solenoid is to start engine and see if the chassis batteries are getting voltage from the regulator. They probably are not. Then have someone hold the boost switch and check voltage again. If you have alternator voltage at the chassis batteries then the oil pressure switch is probably bad or perhaps not connected.

If you don't see alternator voltage on the chassis batteries with either of the above then suspect your alternator.

The boost switch and the oil pressure switch ground the boost solenoid coil so if you have a bad pressure switch you can run a temporary ground to the boost solenoid coil while you are running the engine.

Think I may have found the problem. Sitting around outside last night I heard a ticking sound coming from under the front of the coach. It was the step motor drawing current and engaging the tooth gear. Disconnected the line and will charge the chassis battery this morning. Hope this is it.

Alternator should charge the chassis batteries directly and the interconnect charges the house batteries once chassis up to voltage. When on shore power just the opposite.
