I have a 2005 NPR Diesel Isuzu Truck with electrical problems. Automatic Tranny is stuck on third gear. tranny was already sent for repair and problem continues. The person who repaired the tranny says it is electrical problems. Windows, gauge panel doesn't work as well. I need the wiring electrical diagram to troubleshoot this problem . Thanks.

You may have a problem in your tail lighting circuit as i think that the TCM (transmission control module) gets power from that circuit. I had the same problem with my tranny not getting out of third. I kept blowing a fuse when i would go in reverse in the lighting circuit because i wired in some lights to go on whenever i went in reverse, to much load for that circuit, therefore blowing the fuse. It would also put the transmission into third gear as a safety precaution so if it happened on the highway you would blow your tranny

Thanks Derek. That is why I need the wiring diagram or service manual for that year model truck. I'll verify the fuses again but first time I checked them, all of them were OK. I'll try again.

remove your glove box and on the left you will see a small fuse block with a red and blue fuse the red is 10amp and its blown causing your problem, but that fuse controls 8 diffrent circuits like exhaust brake, lights, windows,transmission, and so on your best solution is take it to an isuzu dealer as they are familiar with this and can usually narrow it down in 2 hours

Have a 2005 Isuzu NPR that will quit running at stoplights, driving down the road, or whenever. It will start up again after a minute or so and keep running until the next time and that repeats 3 to 4 times a day. I don't know where to start looking, it sounds like intermitent electrical problem but don't know where to start looking or testing. I would also like any information where one could get a good repair manual for it. Please e-mail me at mjbailey88@gmail.com as well in case I loose this.

I have a 2005 Isuzu NPR diesel with problems on my stop tail lights, It doesn't go on when I press the brake, I already change the switch next to the brake padel but still doesn't work, Some times I hear a noise behind the wheel and a light comes on from my dash "brake booster" all the fuses are good. Please some one help if you guys had the same problem before. Thanks

open up the dash and right behind the emergency flasher button there is your problem, you should see a wiring harness there grounding out causing the truck not to shut off
