One Response to “Fitting a basic split charge system and relay”

    Good day, eh:

    My questions are that as I plan using the second battery for starting only, will the relay prevent it from helping during start – as in for second storage only? I plan on a RedTop not just because it is 700cca instead of 650 with the YellowTop 34/78, but also it is about $100 Cheaper. If the RedTop goes flat on Start it’s toast. Would two Deep Cycle YellowTops be a better idea?
