Re: fusible link on positive battery terminal
I run 2 batteries on my sportrak, and that uses a 100 amp relay, with the relay triggered from the alternator, not the battery. The relay is hard wired to the battery, the relay Trigger is from one of the small wire that comes out the back of the laternator. It shows a positive charge via meter when the engine Is running.
Thus when the engine has started the relay opens and allows the alternator to charge both batteries. This was all easy to do and including heavy wire only cost £25. Also I fitted a battery isolator switch so I can jump stRt the truck from one battery to the other!
Sorry should have said that the long and the short of this is that a 30amp relay will melt in about 2 seconds when you whack 75 amps through it!
I'm a mod and mine is green!
