OldSub,
6V radio Yes one of my test loads is the 6V out of my truck it is cleaner then if you would put just a resister on it.
How dose it regulate? Well the basic is a zener but it is not that simple.
The prototype is set up so that you could have 200 AMPS going thru it but you are limited to your alternator.
Price I don’t know what it will be for sure but the currant price is looking like about $150 to $175 but I do not know until after I'm dun with UL.
