As you can see there is a battery isolator fitted in the negative cable fitted inside the battery box, as this box is covered with another cover /box the original battery key was too short, so I made a longer one from Bright Mild Steel.There is also a 200 Amp power fuse fitted in the positive cable outside the battery box ( not shown) in case of emergencies/accidents.stina said:Looking good Steve . Where have you put the battery isolator , assuming that's what the key is for ? Is that last pic down Muddyford Quay ? I've missed most of those this year . Will try for this month
