Hi,
I'm currently using a Smartcom voltage sensitive relay to give me a leisure battery charging facility when driving. The Smartcom is fed directly from the vehicle battery but I read a thread a few months ago that suggested it would be better to have a higher capacity normal relay and use the voltage sensitive Smartcom to open the circuit. Am I correct in thinking that the Smartcom relay regulates the charge and that a normal relay doesn't and if I'm drawing the charging current direct, via a normal relay, from the starter battery and not from the alternator (does an alternator give a regulated charge?) am I going to have a problem. I sure could do with some expertise - every time I think I've got a grip of 12v auto electrics something crops up to worry me.
