Cyrix-ct 12/24 V 120 A not engaging

Hello!


I have a Cyrix-ct 12/24 V 120 A connected between one starter battery and two domestic batteries. When the engine is running the voltage between pin 30 (starter battery) and pin 86 (negative) is 13,95 V, but the batteries is not connected. The domestic batteries are down at 12,36 V. I have been running the engine for two hours. I even tried to connect pin 85 (start assist) to the starter battery. Nothing happened.

Is my unit broken?


Best regards

Try to connect pin 85 to the domestic battery and see if that helps. If all the connection are correct you might have a faulty Cyrix.

You cannot use the unit with a smart alternator.
