Hello to you all. I Have a 96 ae101 i was driving back from my brothers house and the car started nice as usual. as i was driving i lost my radio instrument cluster lights, turn signals, ac, and i believe the brake lights.When this happened i just told my self ill check when i get home but first gotta to go to my friends house to pick up some stuff. So as i soon as i got there i parked the car did what i had to do. then my car didnt want to crank at all. but yet my head lights can be turned on and the emergency lights can be turned on. That totally got me tripping. so My friend had push me with his car which was bs.

. so the next day i popped the hood open and check the fuse box the only fuse that was blown out was a 100amp fuse to the alternator. i tried pulling it out and that sucker is melted on there or something. any help or advice would be great thanks.

its bolted in and it blew due to a large short, check your starter cable and alternator cable.

this actually happened to me over the weekend. Was driving fine until the radio went out and lost power to the power windows. Got home and turned off the engine, then thought I needed to jump start it and it wouldn't start. Traced everything to the ALT 100a fuse. I tried searching on this forum and couldn't find much...printed out 5 different suggestions from fixya.com

Sorry if I don't have pics but it took me about 3.5 hours to finally do it.

Anyways, first disconnect the negative terminal on the battery. That's the most important thing to do so that you don't pop the other fuses. Next there are 2 bolts that hold the fuse holder in the engine compartment..the easiest one to see is right near the battery. The other one is partially covered by the air intake box which you can still remove if you use needle nose pliers without removing the air intake box.

Once you remove those bolts, there are 2 clips on each side of the outer shell. You will see lots of wires like black & whites going underneath the fuse assembly. Look for the 3 main sets of type c fuses: AM1, ALT and ABS. On each side of that little section, there are small slits which you need to use a flat head screwdriver to punch down to release those 3 fuses which are held together. Once you release that section, you should be able to pull the set of 3 fuses.

The middle type c fuse is the one to unbolt. I've found that the bolts holding that 100a fuse are different sizes...I think one was 10mm, the other 8mm. Once you take off the bolts, you can then slip out the 100a fuse and put in the replacement. Then just do everything in reverse order.

For me, turns out that what caused all of this was the ground wire to the ground terminal on my 1500 watt amp was loose and thereby caused a loop to pop that fuse.
