Chevy Silverado Battery And Electrical Problems

2004 chevy 2500 HD.
Repairs for this problem = fuel filter assembly.
My truck keeps dieing. Truck will pick right back up. Sometimes i have to restart. It flashes battery not charging in display. A few months ago i had a battery boil and replaced both with new ones. ECM really stumped on this and everyone i ask has different ideas. From alternator to ECM. Got any ideas? If you can help i will tip you.

Answer:
These problems do not sound like an ECM problem. This sounds like a wiring problem somewhere. Stalling without a check engine light or codes is usually a loss of power or ground problem under the hood.

Be sure to check all grounds you can find. Pull on wiring harnesses when it is running to see if you can get it to stall. The battery problem may not be related, unless there are power wires shorted to ground that are not protected by a fuse.

2004 GMC envoy 4.2 Inline 6 cylinder engine.
Battery replaced and vehicle was hooked up backwards.
Question = This car has a draw on the battery and the only way to fix it is to take out about half of the fuses in the rear fuse block. It doesn't matter which fuses i pull could the rear fuse panel be bad. The battery was hooked wrong and it blew the 125 amp fuse that feeds the rear fuse block

Answer:
It is very possible that the short circuit caused damage inside the rear fuse block. A short circuit that was enough to blow 125 amp, could surely melt any part of the inside of the fuse block. May have also melted some feed wires under the block.

I would remove it and look at the wires to see if one or more are shorted together. If not, it may internal to the block.

Question: When I start vehicle, voltmeter on dash shows charge. Fuse # 4 blows out and when I measure across battery terminal, I get battery voltage reading. Same result when I measure from alt to battery ground.Chevy 1996 S-1 0 pickup Engine size = V6 4.3 Lt Vin X. GM Computer codes: Throttle position sensor. Repairs for this problem: Alternator checked O.K.

Alt checks out O.K when tested. My less than perfect manual lists tests under certain conditions to reveal if alternator is defective. Condition remains the same. What would you recommend.

Answer:
If the fuse only blows after the vehicle is started, you could have an internal short inside the alternator. It could test fine, but still be bad. Or, it could be slightly over charging or back feeding a circuit to cause the overload. You should check the wiring from the alternator, as there could be a pinched wire causing the short as well. If all of the wiring checks out, there would be nothing left to do but change the alternator and see if your problem is fixed. I'd be sure to eliminate all other causes before spending the money on such an expensive guess.

Question: I have a 2002 Chevy HD speedometer bounces around, ABS light on. park brake light on, rides ruff on hwy, locked up while driving at 65 mphs truck didnt wont to move.
 Reply: Get all of these things start happening at the same time?

Yes, truck was wrecked the drivers side front end went in ditch... Ever since then drives rough almost like stuck in between 4 wheel drive and regular
 Ok for the feeling that it is stuck between four wheel drive and normal you could have something bent in the front end or even a bad bearing. All the other problems seem to be electrical and maybe related. You may have a short out wiring harness or a bad ground wire.

I changed the bearing i will take it apart and check any of the ground wires put a new hub on it yesterday. I dropped the drive line it still acted up the lights go off but as soon as I hit 25 the Brake and ABS lights come on the sound, sounds like its coming from the transmission transfer case.
 Then also check the vehicle speed sensor which is on the back of the transmission. This will affect the speedometer which will also affect the intellect breaks which can also affect the transmission. Check the wires going to that speed sensor.
