Yandina Combiner 200A Battery Combiner - C200

Item # 889105


The two battery Yandina Combiner 200 battery combiner is a voltage-sensing relay (13.3V) which connects two batteries together when either is receiving a charge. When the charging stops the relay opens allowing each battery operates independently. You never have to worry about switching to "BOTH" when your engine is running and forgetting to switch back to save your starting battery from discharge when you stop.

I have one of these Yandina 200.  I have a 140 amp alternator. Sometimes the combiner will shut down on overload(red light).  Then I have to disconnect both positives to reset it. Is it defective or is that the way it’s made.

Sounds like defective, call tech support they are helpful!
