Silverado electrical problems. Mega fuse? - YouTube Click to view on Bing1:58Mar 05, 2015I was having problems with my 2008 Silverado. The door locks would click on and off & the truck would not start. I did the 10 minute reset and it worked but some say the mega fuse may be going out?Author: sar coxnViews: 97K Intermittent Electrical glitches in 2008 Silverado Jan 20, 2012I had a similar problem in my 08 and I had the crooked auto shop replace the alternator and battery with no fixes. But I did find a solution that has seemed to work for me. Next to the battery on the fire wall is the 175 amp mega fuse box. From what I have read this fuse ends up going bad and makes the truck almost seem possessed.
