    Electrical Build Alternator Question

    I’m at the very challenging part of the build. Electrical System I realize I need to understand what Isolator I currently have. I do not believe it is the B2B kind. I have read that it needs to be based on the Alternator's Amp Max Output, which even though I've looked at several posts on the...

    Dual Sensing Charging through Alternator

    Hi All - Can't seem to find the answer in old threads... I have the aux battery system connected directly to alternator via blue sea acr.

    Battery Isolator size

    I am getting ready to install the Keyline 140A battery isolator to charge my 225Ah battery bank. After I ordered it, I read something that said you should only use an isolator that allows half the amount of your battery bank. So is my 225Ah battery bank too small for this isolator?? Is this a...

    battery isolator phenomenon?

    I'm not an electrical genius, far from it. Hoping someone is... I've got a 255 ah AGM battery bank seperated from the starter battery with a Powerstream isolator. When I start the vehicle within about 4 seconds the isolator clicks open (or closed?) and current flows from the alternator to the...
