[QUOTE="Meroo, post: 296532, member: 8832"] Hi mate sounds like you have voltage drop 8metres is a decent run for a 12v system. Voltage drop doesn't change when connected to a load u can measure the voltage at the battery then go to the end of the cable and measure the differenc there without it connected to a loadd. What you ll find is when you are running a load ur actual battery voltage will decrease slightly this is perhaps where the confusion lies. What I would suggest is either increase cable size or change to a 24volt system where u can have longer runs (most trucks are 24v being far longer then a car which is 12v) . [/QUOTE]
