Had a battery melt down and replaced, but now no power to fuse box under hood and side of dash or ignition. Battery is good and power to alternator.

Checked all fuses and look good. Any way to test relays? Any other main breaker or fuse I’m missing?

1997 Tahoe 5.7L


Thanks

Did you check the two grounds where your negative battery cable bolts to the frame. It might be worth removing them. Make sure the connection is bare metal, clean and tight.

Looks like there is a 40 amp “****” fuse? Not sure where this is located?
