2016 t660, no power in sleeper

60amp fuse under hood mounted to firewall

 

Where on the firewall I’ve been looking everywhere for it including the firewall tia

 

It will be a solid blade fuse. You won't see an element. To check it, take it off and shake it. If you hear a rattle it's blown, or use a multimeter to see if power is on both sides.

That black box is just a housing, the fuse is inside it bolted to two terminal studs.

 

Ok thx I didn’t see anything there earlier but now I know what I’m looking for also I need to check in battery compartment see if there’s a fuse in there

 

What about if there’s no mega fuse?
