In this case the only way to charge the main battery would be through the main battery terminals,or possibly through the white plug.
I have the Cteck plug permanently wired to the main battery,therefore both batteries are charged.If the traxide relay has dropped out,it doesn't take long before it comes in,as it senses the voltage on the main battery only.
