I'm curious for the 912 gurus, is it ok for the integrated alternater on the 912 series to have no load on it? I just discovered last night that my reg/rect is long since burnt out. At least for the last 3 or 4 operating hours anyway. finally smelled a rat after yesterday's flight that the battery took a bunch of charge where some several flights before it was still most of the way charged after the same electrics were used. My voltage would always run low when I had the electrics on so didn't notice it on the voltmeter either. I checked the stator resistance with my ohmmeter according to the heavy maint. manual and that looks correct. Also ran er up with the meter hooked to the two generator leads and got a good 15 volts AC at high idle, on up to 25 and more as I revved it up. So the stator appears to be undamaged. Can't find anything in the manuals about any adverse affects of operating the alternator with no load, which is what the case has been for a bit now. Anyone know? I assume it's ok since it's just a coil of wire with no current flow due to the open circuit. Ordering new R/R on Monday...

Looks like your good to go and just toss another Reg/Rec in and away you go. Everything sounds ok. Depending on how some people set up their electrical system you could damage things (i.e. instruments, ect...) in an instance like this if you took too many short cuts. Do you have a volt meter and/or ammeter in your plane? You should and this most likely would have warned you right up front if the Reg/Rec failed and went on a high charge. -------- Roger Lee Tucson, Az.

Yeah the plane has an EIS in it, with a voltmeter. It's on another page than the one I monitor. Once the battery starts discharging some when I have all my electrics on, the voltage goes down into the 11's and 12's anyway, so when I checked it the last couple times in flight it looked normal. I check the battery with my charger from time to time and noticed it was more discharged than normal the last few flights. Just didn't register till last night that I might not have had any charge.... I was concerned if the lack of load might have hurt the stator, but it doesn't look like it. The R/R I don't care about but that stator would be an expensive nightmare. I probably should put in an outboard volt/ammeter so I can monitor this better....
