So I purchased a 250 amp mechman alternator. It has a pigtail and I need a switched power source. I’d like it to be under the hood anyone know of one in the umderhood fuse panel?

I am not sure the amp draw the diagram from mechman doesn’t say. I’m thinking it’s more of just a signal so my battery and charging lights don’t come one the dash. Right now I have it running to one of the top 10 amp fuses under the dash on the drivers side. But I’d rather just run it to the under hood fuse panel

Give me a few I called mechman and asked about amp draw and he said very minimal it’s mostly a signal wire. Then I proceeded to tell him how I can hear a very faint noise. To which he had me run some test and now my $400 alternator is headed back to mechman to get fixed.

I haven’t posted pics in a forum in forever bro. And I can’t seem to figure it out. But literally it’s a small plug that fits into their alt and into my factory harness with a long blue we’re for a switched power.

The owner's manual for my '04 Hoe has a great diagram of the underhood fusebox, along with all the fuse descriptions. Might start with your manual.
