Blown fuse issue on 02 LB7 Duramax (INJB 25A Fuse)

I keep blowing the 25A INJB fuse. It is an intermittant problem and I cannot seem to pin down a regular cause.
What happens is I will be driving long and the truck will just die (no fuel as all electronics still work). Trying to restart is vain until the fuse is replaced and it might take more than one fuse before it will start.

My truck is a 2002 Chevy Silverado 2500HD CC,LB 6.6L Duramax (diesel) and the Allison 1000 tranny.

I have found that when you are going to engauge 4x4 high, it is best to only be going about 3 miles an hour. Not faster, not stopped. It likes some movement to help it mesh. I've had perfect shifts since I started this. Hope it helps. Wade.

these transmissions have three sets of planatery gears the whining you hear is simply the gears doing thier job. You have to remember the allison trans is basically the scaled down version of the heavy duty isuzu truck trans they are designed more for thier load capacity then for comfort

SOURCE: 01 duramax allison changed fluid and filters now in limp mode

Make sure you have the proper amount of tranny fluild in it and get that Valvoline fluid out of it. Allison transmissons have there own type of tranny fluid and you want to use it. You can buy the right stuff from a Allison dealer. Most Detroit Diesel dealers are also Allison dealers. Look them up in your phone book and they will tell you the quanity and sell you five gallon pails of the fluid. Just get the serial number off of the side of the transmisson before you call. Change the fliters again too. Believe me, this is important. My company has Yard horses with Allison transmissions and you don't want to screw with the small stuff. Service them right and they work as hard as you want.

My fuse 25a keep blowing in my Mercury Grand Marquis 2001


That is not enough info to give a suggestion. What circuit is the fuse for - look at the fuse box? What happens when the fuse blows? Did something get wet or damaged prior to the fuse start blowing?

What could cause Ignition 1 no 2 fuse to blow intermittently


aI dont recommend it but you can try a higher amperage fuse to see if the problem happens. Fuses are really not currently limited, they are there for short circuits, if yours is blowing intermittantly, you might have a connection probelm etc.

No ac nd my fan stop working completely


Fuses blow because of higher than normal amperage in the circuit. Not sure what circuit the blown fuse is for but if it is for the fan the fan may be shorted therefore blowing the fuse. If you put fuse in while the ac was still on try shutting off the ac then putting the fuse in. See if it blows then if it doesn't then turn the ac on and if it blows you have at the very least isolated the system at fault.

25amp fuse blows when ignition is tured on volvo940 gl 1994


Disconnect (unplug) all the units that are supplied by the 25A fuse.
Switch on ignition and check that fuse has not blown- if it blows under these conditions the short or overload to ground is:-
a) in the wiring to one of the units,
b) or there is some other unidentified faulty unit still connected.

Re-connect each unit one at a time, observing fuse status.
If one of the units has a short / fault, it will blow the fuse when it is connected back in circuit.

Cooling Fan Fuse


Sounds like a short in the wiring, or a bad fan motor drawing too much current. Check the wiring for shorts, if none are found, replace the fan motor.

Electric seats won't move - Silverado 1500


depending on what year truck it is, there is a 40-60amp maxi fuse in the underhood fuse block that can also blow, the harnesses get stuck on the backside of the seat tracks and blow the underhood fuses.
