 Posted: Tue Oct 28, 2014 5:57 pm Post subject: Voltage Regulator Question |
 |
|
I have a Rotax 503 DCDI on my Firestar with a three phase regulator that's got me wondering. After I start the engine (electric) & turn on the EIS, I get a warning light and the EIS flashes 16.9vdc, slides up to 18.2vdc. This lasts about one minute and then the voltage slips back to about 14.4-14.5 & stays there. This has happened the last two times that I've flown the plane.
Has anyone else experienced anything similar to this?

I've never had the problem... first thing I would look at is whether the
sense line to the voltage regulator from the battery/ 12 v buss,,, has a
good connection. sometimes a bit of corrosion will cause problems....
pull and reset the connector, and check the wire connection to the
connector.
educated guess.
