My 1997 Chevy suburban k1500 5.7L keeps blowing the 20-A ENG 1 fuse
I had this same problem with a 1997 Z71 K1500. That fuse was receiving power from the ignition switch in my truck. After putting 4 ignitions in it in 6 months, I finally figured out that every time I put the transfer case in 4Low, the service engine light would come on & the ignition switch would go bad soon after. The electric motor that engaged transfer case was bad. Every time I engaged 4 Low, It would throw power surge to ignition & blow it up.
IWILL TRY THE SOLUTION IWLL GET BACK TO YOU
