My friend has a 03 predator, and he was down at my house later this night and he battier went dead. So i got my quad pushed him down the road and tried to bump start it, it worked. When we tried to turn on his light it keep on backfireing on him.

 

The predator charging system is only good to maintain a battery, If a battery is already dead you have to use an external charger or a new battery to fix this. The backfiring is probably from low voltage due to the draw of the headlights.

 

My pred does the same thing it will not charge a dead battery you will have to use an external charger

 

quads really dont have a charging system like cars do. thats y you cant use yoru quad to charge the battery
