    Sounds like your alt is overcharging the electrical system. You'll have to take out the alternator and take it to the parts store to be tested.

    The gauge measures voltage, not pressure. Although it is a 12 volt system, a properly functioning charging system will generally have an output in the range of 13.8 to 14.4 volts. New components do not always equate to working components. Check your connections, looking carefully for evidence of corrosion or electrical arcing, and if all looks good then get it to a shop that can load test the battery and charging system if you do not have the tools to do so.

    Is your alternator is re-manufactured?

    If hooked up properly, that's probably 99% of your problem. You should have a warranty with it as well, I'd take it to get it tested, but if they say it's good, return it and try another one. It's the way of remanned world, they polish a turd and sell it.

    There is a little wire on the bottom of the alt. that is known for getting broke. If it was broke would it cause this problem??
