So this past weekend while doing some night riding I noticed my lightbar would almost dim down for a second then come back full strength. I am running the dual battery setup with all accessories running off secondary battery. The only additional accessory I'm running off the main battery is Chupacabra led cubes for the headlights. I was running my 40" rough country dual row lightbar, tusk seat heater (only 1 seat), and wicked Pecker Off-road heater. Watching my dual volt meter, I noticed my secondary battery would drop to roughly 10.8 volts and primary would drop to roughly 11 volts as the voltages were fluctuating quit a bit. I turned all the accessories off except the light bar and turned off my brights on the headlights and still noticed the sporadic dimming and voltage all over the place. I also have a torque locker so not sure if that eliminates any additional power required since I'm not utilizing the i-4WD. Would this be a sign of the primary battery starting to fail? Any thoughts, I have checked all wiring and no loose connections that I can find.

need pics of your rig, you may be asking for someone else , need proof u own this

need pics of isolator\battery\etc....


describe voltage jumping around, when sitting, when bouncing around, etc....

advice to check

-main positive wire rubbing somewhere
-loose\corroded ground
-voltage idling with nothing on, voltage idling with everything on = both batteries
-have both batteries tested
-failing\cracked positive post going to ground

if u have everything off, and both batteries are still doing it, its something common

Have you tested both batteries? If they're good then maybe check grounds...??
