Braking kills the lights

[Jim832904]

Touch the brake pedal and all of the lights go out. The breaker resets and lights come on. Will repeat consistently. Have looked for bared wires , have removed and tried without brake light bulbs. Cant find a cause. Everything I can see looks ok. What can I try next? M929-A2.

Does it do it with the turn signals on? Like throws the breaker, If not look for the brake light switch to be shorted out or the wires to and from it.

Drivers side inner frame well just to the rear of the fuel tank

Thanks! Unplugged the switch and lights are staying on. !00% offroad use so it's fixed.
