If I do the Mad Electrical mod and install an additional direct routed charge wire, any reason I can't remove the factory alt charge wire altogether?
I guess I'm not understanding you then? You're taking about completely removing the black wire that was originally hooked up to the alternator correct?
If that is correct, then look at the second page of the Mad article again. They have you remove that wire from the alt and connect it into the existing fusible link that is attached to the red interior feed wire. The remaining black wire under the dash and the black wire on the alternator are the SAME wire.
I think you are thinking of the wire that you splice in btw the starter relay and the remaining blk (alt) wire under the dash.
What I'm saying is that you don't have to splice in a wire to the starter relay and the remaining black wire under the dash if you leave the wire connected to the alternator...they are the same wire.
