Question Yanmar 3YM20 Oil Pressure Alarm with B Engine Panel

Yanmar 3YM20 Oil Pressure Alarm with B Engine Panel
I have 2 Batteries one Starter one House.The problem is that any switch on the panel on the the house bank when switched on causes the oil pressure alarm to activate on the engine panel.

The switches for everything on the House bank main switch panel have all been re - soldered and duff diodes have been replaced.

With all House switches off the engine starts normally with the oil alarm on then turns off when the engine fires as it should.

The engine and its ancillaries has only done 197 hours since new.

There is more I could tell you but I don't want to confuse the issue with things that might be not be relevant.

So please ask me your questions.

Your suggestions will be gratefully received.
