Question about 2005 Chevrolet Avalanche

1 Answer

Does the 2005 avalanche have a mega fuse for the alternator/battery and if so where is it located

I'm having power problems with my truck. It will start when I jump it but when I disconnect the cables it turns off. I've seen that some vehicles have mega fuses for the battery/alt and I was wondering if mine had one so that I could check that before buying a battery or new alternator.

    I know the battery is dead now, but I need to know if the cause is the alternator not charger because it's bad or if the mega fuse is blown (if I have one on my truck).

I'm no mechanic but did you add any accessories to the truck.
Lights GPS System Sound system etc etc.
An stereo amplifier that would not shut off with the deck cause it's shorted would kill that battery every night.
I myself had added a set of driving lights and one of my Relays I had installed Jammed and it would do the exact same thing.. all day no problems.. but overnight wont start..
If I remember correctly you disconnect the negative from the battery and connect a Test light from the battery to the disconnect lead.. if the light turns on theres a load on the system.
yes you need to disconnect the light of the hood or push down on the switch to leave it off.

Hope this helps took me 2 weeks to find my dumb relay issue.

The reason the fuse blows/melts is because there is excessive draw. The other alternator could be wired wrong. Check to make sure the wires are correct gauge.

your fuse box is inside , lower left kick panel , check all fuses in there , then also in the engine compartment on the firewall around the middle is a junction block with like 2 fusible links , they need to be tested , and also 1 fusible link right off the positive side of the battery , test it also , if you don't have a test light for testing , you can kinda wiggle the fusible links and feel if they are limp and stretchy , that's not a good sign , you can buy replacement fusible links or fusible link wire from local parts store , depending on how much sparking happened you may have blown the fusible links . if you don't have a test light , pick one up at the parts house and learn to use it , it will be invaluable when it comes to testing this kinda of failure . cheers .

SOURCE: Chevy Avalanche won't start

If you're getting no power at all when you turn the key to start, try disconnecting the battery and then hook it back up. Chevy has had some problems with an ignition relay solenoid that's mounted under the driver's side dash. Disconnecting power could reset the switch....If that seems to be it, a replacement is around $250. at a chevy dlrshp.

All the dealerships have a TSB concerning this very problem. It concerns a possible loose connection at the 175 amp mega fuse located near the passenger side cowl. Tell them to get off their sorry behinds and fix the problem.
