I have a modified 81' MonteCarlo. I have a Smallblock 383cc in it. I installed a dual battery system utilizing an Isolator. Yesterday my headlights did not come on via the existing light switch. Maybe its a fuse but I want now to bypass the existing switch control for the reg & the high beams to 2 separate switches that would then feed off the 2nd battery. each new switch would feed a relay that would then activate the two reg beams(via 1st switch) and the high beams via the 2nd switch. I would still have to utilize the existing switch to controll all the other lighting other than the lights above mentioned. I want to do this to elliminate the draw from the street and high beam lights on the battery that powers the engine robbing some current to it when they are on. Any thoughts on this?
