My brother 450es has started doing some wierd stuff last night. While idling the headlights suddenly dim for a few seconds and then go bright again. I think his battery might be weak and the regulator is having trouble charging it. It might just be a loose conection to. I just wanted to know if anyone has had this happen.

 

Yes my foreman did that I checked the bat cables and the pos was loose after fixing the cable my problem went away.

 

Thats kind of what I figured. He said he had to jump start it a couple days ago and was messing around with the battery. Ill have him check that first . Thanks
