I decided to install some extra ground wires in hopes of improving the idle (gets really low when warm, with headlights and brakes on) and the headlight brightness. I ran an addtl ground wire from battery negative to stock ground block, and a ground wire from a/c bracket to right strut nut (one of the three nuts in right side engine compartment). Then I got a wild idea and ran a direct hot wire from battery positive to the hot lead on the alternator. Now, i'm thinking that the lead to the alternator was rather small, and I added a second 4 gauge wire - maybe I'm getting to much electricity to the alternator?

The car runs fine, no change in the idle or headlight brightness noticeable (well - headlights may be brighter, but I also sanded and compounded and polished the headlights, so they are clearer).

Anyone think i did a bad thing by running direct 4 gauge wire from batt positive to alt positive?

Thanks for any input.

Nope, it's fine. The standard wiring is basically the same thing. It should be fused though.
