    Ammeter Install ***HELP***

    I'm trying to install the Autometer Sport Comp Ammeter but I ran out of ideas.
    I can't get the gauge to work. The directions say to:

    1.) Install the red wire to the positive side of the battery

    2.) Install the other wire to the B+ output wire on the alternator

    My interpretation is that the B+ output wire is the big red wire comming of the top of the alternator.

    So I hook both up, and I don't get any readings.
    The ammeter should read negative when I leave the car off and put the lights on, but it onlyu moves about 1/32 of an inch to the positive side...

    Any help will be appreciated!

    Well in case you guys are reading this because you're having the same problem, I think I came up with a solution.

    To install an ammeter you need to splice it into the B+ wire on the alternator. That's the really thick wire with the red cap comming off the top.

    So I'm bailing on the ammeter and getting a voltmeter.

    To do the install properly you would need to run at least 10 gauge wire to your gauge and back.
    In other words, as the alternator charges your car all that energy would have to travel through the ammeter in your pod before it goes to the battery...thats asking for trouble

    sounds like you're missing a part, there should be something that goes around the wire from the alt, and reads current passing by
