Not best pleased lost a whole days work because of a poxy 15amp fuse. Got to first job all seemed ok until water flow from brush started slowing up. Turned up controller made no difference. I thought perhaps pump is KNACKERED changed pump (carry a spare) still the same prob Went to local auto electrics who supplied my new leisure battery 2 wks ago and electrician was on holiday. Great, what to do now. Phoned mobile auto lec couldn't see me til 3pm..... Finally got all checked and a 15amp fuse had blown on the relay so my leisure battery hasn't been charging and losing power when using pump.. A POXY BLOODY FUSE. He advised me to fit a voltage sensitive relay! Anybody got this set up?
