Did your battery charge sufficiently to provide power to the transponder, navigation lights, etc? Matt After about 20 minutes of flying the current into the battery went from 20 to 30 to 40 to 50 amps before the alternator circuit breaker (CB) blew. I shut off the master and let everything cool off for 15 minutes. I am sure glad that I have magnetos. I hand flew the plane using my handheld Garmin. I then reset the CB, turned on the master and then the alternator. The system charged for about 3 minutes and then shutdown again. I turned the charging system back on every 10 minutes for the next 2 hours and finally the charging current went below 40 amps and stayed on. I tested the battery temperature by hand and estimate that the battery got to about 140°F. ------=_NextPart_000_015C_01C560A0.0A218550 Content-Type: text/html; charset="iso-8859-1" Content-Transfer-Encoding: quoted-printable
