Landcruiser 24v split charge
Hi there,
I have a HJ60 TLC, 24v, with an optima dual battery. I want to run a split charge relay from the 24v system to charge the 12v battery. So this requires 2 components - the relay and the voltage convertor.
The problem is that I'm not sure which way round they should be wired up?
It could either be:
OPTION 1:
24v Source >> 24v voltage sensing relay >> 24v to 12v convertor >> 12v Aux Battery
OPTION 2:
24v Source >> 24v to 12v convertor >> 12v voltage sensing relay >> 12v Aux Battery
In the first option I dont know if the convertor bewteen the relay and the aux battery will effect the 'voltage sensing'. In the second option I dont know if its a bad idea having the convertor directly wired to the 24v source, always connected, risking running the battery down.
And then just to add to it, i dont know what specification the convertor should be to handle running an engel fridge etc.
I've spent hours searching the web about this - if anyone has any ideas or comments it would be very much appreciated. This 24v business is driving me bananas!
Many thanks - Andrew
