Alternator question, battery is discharging quickly.

For the sense wire, you could technically run a wire from the B+ on the alternator to the pin, but the voltage at that pin is used as reference for regulating... If say, your battery is in the back, the voltage read at the battery will be less that at the B+ "output" of the alternator... This could make the alternator regulate the voltage .1 or .2 lower than it normally would in stock config, or what you would prefer.

so, its good practice to have that sense wire be at least a little bit down the line from the alternator... If stock its hooked up at the fuse box, its probably best to hook it up there.

I sent my decrepit harness off with a request to have these wires run within the new one.

But yes, I have done that temporarily in the past.
