Hi everyone,
Just purchased a LED light bar from eBay and have a few questions before I wire it up.
In my D40 I have the start battery in the front and the 2nd battery in the canopy. They are joined by 6 B&S cable with a Redarc Smart Start solenoid mounted near the start battery in the front. The light bar will be installed on the front of the roof rack on my canopy.
The light bar draws 15amps at 12v (180W) which is a fair bit.
It will be hooked into the high beam wire for legality and have a seperate switch to separate it from main high beams.
So im thinking its easier to get power from the 2nd battery in the tray as this is an easy run to the light bar on the roof rack. But, is drawing 15 amps from the 2nd battery a good idea? From what I know of the alternator and redarc isolator type setup, I wont be putting in enough amps to compensate for that amount of draw. With that being said, I am upgrading to a D250S Dual (20 amp DC to Dc charger) as soon as funds permit so I need to bare this in mind.
So really mains questions are:-
Should I get power from start battery and run at least 6mm twin? cable from the front battery to the relay in the canopy and then to the light bar?
or
Should i get power from the 2nd battery and run cable to the relay and then to the light bar which would be a much shorter/easier run?
I have to run the high beam wire from front to back anyway although I could mount the relay in the front I guess. I think I will mount relay in the back though as this means I can just switch the high beam wire in the cab easily on the way through to the back.
Distance from front to back is probably a 5-6m run once I have gone through where i need to etc so not sure if this is to bigger run to get power from the front?
Any help or ideas appreciated.
Cheers Martin.
