Just a quick question from a peon 235 driver,
 
 I am running a suzuki 55 amp alternator which i have removed the voltage
regulator. I am using the old ford style regulator mounted on the firewall. 3
weeks ago I was taxiing in and my voltage dropped so low 10v that my dynon
glass panel went black and then came back on.
 I turned everything off and the voltage went to 14.7. Turn on the landing
lights and loaded it up and it was back to 10 v or so.
 I replaced the voltage regulator as that was a cheap fix. It is still
happening. The voltage hovers around 14.5v with little load and drops to 12.5
or so  with a load at cruise.
 
 Is this just a simple case of the alternator needing rebuild. It has around
400 hours or so..
