I wanted a way of isolating all the ancillary equipment in one go, so an isolator for the fuse boxes and one for the winch.
Car dual battery isolator wiring diagram plus#
Leeds wrote: Your fuse boxes have a 100 amp fuse in line plus a relay isolator? Just wasnt sure if the more expensive one was complete overkill! its the one which doesnt have the remote button. I was thinking of one of those bluesea 120a ACR. Leeds wrote: Is your ACR a linkable one? Useful if main battery goes down or doing lots of winching. Ive measured up and they should fit in the battery tray Ive bought 2 Numax CXV-X 1000 which are both leisure and starting as i understand it. Leeds wrote: Is your auxiliary battery a starter/leisure battery? Winches draw high currents whereas radio etc is low. Leeds wrote: Why use a 4 post bus bar? A stud terminal connector can take 4 35mm2 cables i was thinking of balancing the load across 2 fuse boxes, but it is total overkill tbh. Check on phyiscal size of fuse boxes if putting them in main battery box Leeds wrote: Why 2 12 way fuse boxes? That is 24 extra circuits rather a large number I would have thought!. No fuse on winch? just an isolator, as i read that winches draw a variable current which means id have to put a very very big fuse in place defeating the object?Ĭhassis earth back to bus bar not battery? thoughts. VSR = Bluesea automatic sensing relay for battery charge/dischargeĤ-POS BUS BAR = Those metal bars with 4 posts which you can use to tidy your electricsġ2-DIST FUSED = A 12 way fuse box for connecting ancilliraries given i know a number of people have put dual batteries into their defenders then im asking what you think of my wiring diagram! whether its any good or complete cobblers!ĮXT AND = External anderson connector for jump leads So i thought id put together a wiring diagram which i can then show a proper auto-electrician and get a quote for the work. Ive now bought the 2 batteries and have started to plan out what electrics i want on the vehicle and how i want the wiring arranged. My batt recently died on my 90 which spurred me on to sort out a dual battery installation.
1st post been lurking for a while and on other forums.
