Subject: JabiruEngine-List: alternator voltage output
From: "curts63" <curts63@verizon.net>


My question is this, what is the normal output of the alternator in voltage?  My
volt meter is reading up to 14.7 volts when running around 3000rpm.  Is this
normal or should it max out around 13.7?

If this is high, I guess I need a new regulator?  My problem is the Garmin system
seems to fluctuate as the voltage gets up to 14.5 or more volts.  When you
pull back the throttle and let the voltage drop, things settle down.

Thanks,
Curt

    13.8 is the MINIMUM needed to fully
    charge a lead-acid battery . . . but it
    takes a LONG time to top off. Starting
    batteries in vehicles are generally recharged
    at 14.2 plus/minus 0.2 and 14.7 is not
    too high.

    Is this a piece of aircraft hardware?
    The voltage level you cite should be
    no problem. What system are we talking
    about?
