    No matter where i get 12v from (straight to battery, junction box on psgr side firewall, or a term strip on driver side) the light flickers when turned on; and the electric brake box light flickers.

    If i go straight to a external battery, the light bar comes right on ; both direct and with the switch mounted in cab. Any ideas on what could be going on ?

    Ditto what Mat said, that and bad grounds. If you are using multiple power locations and having a consistent problem, you are most likely looking at bad power source or bad ground off the battery.

    Got tired of chasing ground & hot. Ran straight from battery. Works great. Thunder approves! Should help us check hog traps easier now & run backroads


    & yes,,, that is a dodge tow mirror. Once I get the drivers side on I will do the write up on them.
