battery isolator

[jmvotto]

Can the dual battery system be wired in isolation from starter/alt and stereo amp without an actual isolator. I paid for the install and looks like the two batterties are wired together, with the starter/alt on battery 1 and amp on battery 2. Then they are wired together. + to + an - to -

Positives must be separated to in order for isolation to correctly work. Sounds to me like they wired it so to allow for disconnect when starting is all. The way it sounds it'll still drain the start batt. Without seeing exactly what they did it's hard to tell though.

The positives need to be seperated by some type of isolation device whether it is a relay, electronic or switch. With the positives connected together, the system sees the two batteries as one large one and isn't the same as what you intended.

it separated by the same breaker that was there with just one battery. Does that make sense. i should have snaped some photo's

Does anyone know if you can extend the main power supply lines from the alternator to the battery. I don't like the placement of the battery in the "hole" takes up space. Distribution block with 2 gauge wire or is that a No No.

The cheap and easy way out it to get another cable and bolt the two together using a regular nut and bolt. Then insulate it so it doesnt short.

The correct way is to add a breaker to extend it, breaker acting as a junction and protection point.

The other more correct and possibly the best way is to measure the length of cable from the start < alternator > to the location you want the battery in. Then have a custom cable made at that length and rerun it.

They actually make posts for that purpose or as a junction, gotta remember what they call the blasted things.

Her ya go, they are called JUNCTION BLOCK STUD TYPE ~ NON FEED THROUGH, it's the bottom two. Mount them wherever you want and bolt the cables on, totally insulated. I didn't look but you'll also want to cover these somehow. Check out Waytek they have everything!

Perfect, I will try and find the covering for the studs.
