    How can I improve on factory electrical system?
    « on: December 26, 2007 - 03:41:17 PM »
    I would be interested to hear from anyone regarding any modifications/improvements they have made or might recommend to the factory electrical system. The car is a 70 Challenger 383. The only thing I have done to date is to bypass the factory ammeter gauge (will replace it with a voltmeter). I have heard this will also make the lights a little brighter, as all electrical load runs throught the original factory ammeter. What else would you guys recommend? Would a different alternator, or a headlamp relay help?

    Try:

    They are not the cheapest way to go, but the kit was complete and has been very reliable. :2cents:

    Are there better alternators on the market besides the stock unit? Are single wire alternators any more reliable? Also, are all voltage regulators created equal? My car is all stock but I don't care if these components aren't.

    Powermaster makes a 1 wire alternator, that is voltage tested, and much better then stock. Lights are brighter, and it is in a stock case, so the modification is barely noticeable.

    any 4 or 5 pin 30 amp realy will work , you can run 1 under dash before the dimmer or run a pair out by the starter relay

    Actually the MAD site explains that the one-wire is inferior to the 3-wire.
