About a month ago, I purchased a 2006 Regal 2860 Window Express. I'm having an issue when I turn on the starboard battery switch (also house battery) after a couple of seconds, the dock's 30amp breaker trips. I can't have both one at the same time. One or the other.
Looking online, read that it can be a faulty battery charger. For the time being, I isolated the charger with a separate outlet off the boat and the issue still happening.
I suspected it could be the charger, so I isolated it from the boat, made up a and outlet for it and plugged separately to 110 outlet to ensure my batteries getting charged.
I suspected due to a very dead house battery that for some reason can trip it. So I took out the house battery, chargered it off the boat and it tested good.
I have attempted using my neighbor's boat power cord and his side breaker. Again once I switched on STBD engine/house battery switch on, his breaker tripped. That confirmed that it isn't a cord/plug issue
At this moment, I have the breaker on, shore plugged into my boat to power up my AC unit, I have extension cord from the slip's 110 outlet directly to my batteries charger to keep it full.
If I need to 12v DC power, I have to switch the STBD switch on, everything works but I trip the shore slip breaker.
I turned off all breakers inside the cabin (AC and DC). Turned off the shore power switch on the boat. I can still see my cable red light on indicating that the slip power feeding through the cord.
I switched on the house battery. Then switched on the shore power switch. No load on. The slip breaker tripped as usual.
Any discussion is appreciated.
