Yesterday I hooked up my new inverter to my dolphin house battery so I can charge my laptop when I’m not hooked up. The installation went well and the invertor works. But I’m getting a click and ping noise now coming from the breaker box, i unhooked the invertor and returned wiring to how it was previously but I’m still getting the same. My switch board does not light up anything and water pump sounds tired when I turn on, lights come on but dip when the breaker box click ping every 20 seconds. When installing the inventor I struggled to fit wires through plastic gromit on the metal box where the auxiliary battery sits so I pulled away cork and moved grommet to make room for new cables. What did I do ? Iv unhooked it all to be safe because I smelt burning inside when I turned the engine on, Please help I’m powerless !
