DieselDog5.9 Posted March 30 Share Posted March 30 I have an 03 CV713 Granite, the truck died loaded a few weeks ago, found fuse #7 blown, replaced the fuse fired right up. Fast forward a month truck died again, replaced the fuse again fired up, 30 minutes later fuse blown and wont take a fuse without blowing with the key on. Pulled it out of the road, went back a few hours later with a wiring schematic, pulled the ignition switch out of the column, put a fuse in fired right back up. Looks like that fuse powers the key switch, then powers the Accessory relay, and the emergency stoplamp relay. Havent found the accessory relay or emergency stoplamp relay yet. When broke down on the road noticed with the key off, and the ignition switch fuse blown, the brake lights were on. Is this a known issue for these trucks that I am chasing?

Joey Mack Posted 4 hours ago Share Posted 4 hours ago ''D''.. can you start over, and give us the year of the RD? and a better description of what happened? is the blown fuse #40, in the fuse box under the hood? Quote Link to comment Share on other sites More sharing options...
Deunis Posted 4 hours ago Share Posted 4 hours ago Hola joey 2000 me pasa algo parecido a esto. La camioneta se averió cuando estaba cargada hace unas semanas, encontré que el fusible n.° 7 estaba fundido, reemplacé el fusible y se encendió de inmediato. Un mes después, la camioneta se averió nuevamente, reemplacé el fusible y se encendió nuevamente. Treinta minutos después, se fundió el fusible y no acepta un fusible sin fundirse con la llave puesta. La saqué de la carretera, volví unas horas después con un esquema de cableado, saqué el interruptor de encendido de la columna, puse un fusible y se encendió de nuevo. Parece que ese fusible alimenta el interruptor de llave, luego alimenta el relé de accesorios y el relé de la luz de freno de emergencia. Todavía no he encontrado el relé de accesorios ni el relé de la luz de freno de emergencia. Cuando se averió en la carretera, me di cuenta de que la llave estaba apagada y el fusible del interruptor de encendido estaba fundido; las luces de freno estaban encendidas.

The blown fuse is inside the cabin in front of the co-pilot The truck broke down while loaded a few weeks ago, I found the fuse inside the cab in front of the passenger side was blown, I replaced the fuse and it came on right away. A month later the truck broke down again, I replaced the fuse and it came on again. Thirty minutes later the fuse blew and it won't accept a fuse without blowing with the key in the ignition. I took it off the road, came back a few hours later with a wiring schematic, pulled the ignition switch off the column, put a fuse in and it came on again.

Joey Mack Posted 3 hours ago Share Posted 3 hours ago ok, sounds like a power wire is shorted to ground. did you identify what circuit the fuse protects? any fault lights/codes Quote Link to comment Share on other sites More sharing options...
