Alternator Issues 6.0

Hey all,

New to the excursion and 6.0 world. Attached is what happened to the truck today. Bought this truck with a sinister diesel alternator (and many other upgrades) and was working fine, no issues for the past 8-9 months.

Kept getting intermittent flashing battery light on the dash today, so I popped the hood to find one of the connectors loose and melted the housing box. I’m not knowledgeable when it comes to electric work. Any thoughts on what happened/ where to start with repairing? Thanks!

you just need to replace the entire fuse box, and use new connectors.

this looks like the one you have, but I suggest it is not big enough to handle the current

I would suggest that you get this one, it has twice the current rating.

I found the one after some digging:

looks like it goes up to 400a so I’m still scratching my head on what possibly went wrong all of a sudden.

Probably the meltdown was caused by a poor connection where it failed. Intermittent connection causes heat, causes failure, but not at 400 Amps. Unless the truck (stereo/accessory lights Etc) or a shorted connection is actually consuming 400 amps, that fuse will not blow.

I agree,
the connection got loose and when that happens, they get hot.
