Back-up/ night lights on 2003 9400 international

No relay, just a fuse. Most trucks it is F4-C, but always check your label on the glove box. It should be powered all the time.

 

Thanks, I'll check it out. I thought it was a relay, thinking the tranny switch was the signal wire.

 

HeavyD I'm wondering where my day time running wire is tied in with the low beam lights am looking for the location please

 

Check for 64C, 14 gauge yellow wire at 87A of the dimmer relay. Should be tied into 53B, 12 gauge yellow which is the feed for the low beams.

 

Heavy d, I looked at my fuse and wiring. I found that there is no continuity at the switch when the transmission is in reverse. I pulled out the switch and checked continuity by pushing the ball at the end of the switch and it was good. So how do I fix the fact that transmission is not pushing the ball up?

 

The shift rail isn't pushing up enough. I highly doubt it is worn down in the trans. The cheapest thing is to replace the reverse switch, even though you manually tested it was good. If the problem persists, then it is internal to the transmission and likely not going to be cheap to fix.

 

HeavyD on 9900 international the blower fan breaker jumps at #4 setting its pulling 32 amps but at #3 and lower it pulls under 15 amp what could cause that? Brand me fan

 

On high speed, full 12 volts is feed to the blower motor. All other speeds go through the speed resistor block. If you unplug the fan and amp draw goes to zero, your fan is faulty.

 

Why does my fan belt keep going off the pulleys what should I checked my idler already it's solid?? #confused

 

Something is misaligned. Usually it is automatic belt tensioner that goes.
