Title: Battery isolator switch Post by: Clive on January 22, 2017, 08:39:37 AM If I were to install a simple on/off battery isolator switch, would it matter whether it was fitted into the positive, or the negative side of the battery wiring?
Title: Re: Battery isolator switch Post by: spanners on January 22, 2017, 09:12:24 AM it depends on what its controlling , if its just for anti theft i put them in the earth lead ,, infact i fit most that way unless they are being used to isolate the supply to an accesorry or winch etc
if it is to be fitted to ,motor sports regulations, then it needs to be motorsport approved and it will come as a multi pole switch and also isolate the vehicles alternator at the same time and therefore it can be used as an emergancy stop switch also Title: Re: Battery isolator switch Post by: dr big750 on January 22, 2017, 02:22:53 PM Spanners is correct in everything he has said, I was involved in motorsport and have used these.
I also have them fitted to my camper van, on the negative lead, and work well to totally isolate the batteries when stored for a while, but must be the only connection to the earth on battery or else it will not isolate everything.
