AV Camper Conversions

Customer popped in yesterday with his motorhome complaining about his DC2DC victron unit not working.
Was installed without ignition live trigger and not set up correctly.
Fitted a fused ignition live and set up to enable proper function. Unit still didn’t run consistently, with a measured low voltage input from van battery. Voltage was fine at van battery so checked the cabling and fuse. Inline switchable fuses from Amazon had been fitted by someone and were causing the issue.
Fitted new midi fuse holders and fuses and all good, with consistent charging when engine running.
Never buy cheap unbranded components for your electrical system.

Split charging not working. Found the fault to be a bad earth connection to Leisure batteries. This is why you don’t screw through van floor to connect to chassis earth. It eventually corrodes.
Due to run of earth cable I ran a new one from internal bodywork after cleaning paint to ensure a good connection.
