Greetings,
I have an International 9400, when i start the truck it starts fine. I rev the truck nothing happens, but as soon as i start driving it the lights begin to flicker. Truck and trailer lights flicker, except for my dash lights. I checked the battery/alternator connections to make sure nothing was loose. Went around wiggling cables to see if that would cause it to flicker and nothing. Any idea what could cause this?
