My headlights were dimming REALLY bad but I used some 0guage wire that someone gave me when i bought my sub and bought like $7.00 worth of parts (New battery terminal meant to except thick wire and a copper loop end so I can ground it.) Figured I might as well get started on big 3 but WOW didn't expect that one wire to really make that huge of a difference. I just did the negative battery to chassis ground.
they BARELY dim now and it's very acceptable. Thought this might be useful for people who had the same problem and wanted a quick solution until you go under your car to do the rest or get a second batt. etc. Most dedicated electronics stores (Not radio shack) will carry all different types of wire and youc an get 1ft. of 0 guage for $2.50 and the rest of the parts for $7.
Well, the reason I wanted a second battery with an isolator was because I travel by road a lot and would like to listen to music while i'm parked or charge my accessories possibly add an inverter for DC outlets, etc. And not worry about draining my starting battery , when it's out it's out and i can still start my car. sometimes i'm parked for 2-3 hours at a time
Well, the few questions I had were.
1. I have been reading that you want the same brand of battery, but with an isolator this is not an issue. If this is the case, I wanted to get a massive battery as the second one so I can have as much juice as possible I'll hunt for a while till i find one cheap. Will there be any issues with mixing the battery types with an isolator? Will the big battery make that much of a difference over a smaller one? Does it make more sense to put the big one up front?
2. Second question is. What type of amperage should i get for the battery isolator? I've found 90ampere isolators for dirt cheap and was wondering if this is enough, If my 100a circuit breaker is constantly tripping i'm guessing that it wont be enough, but I don't know how it works with battery isolators. If it's the amperage in between batteries or if it's rated for the power you will be pulling on the second battery.
Thanks in advance guys.
