Charges at 2amps, no interference noticed, looks good panel installed. Wish a two port version was available from Stein back then. On 3/23/2018 9:48 AM, Art Zemon wrote: > John, > > Thank you!

Years ago you published a piece on how to make a little flap lever out of a solid piece of aluminum that goes over the toggle and gets held there by a couple of set screws. The only ones I have found all have bats or toggles that rotate and this is not good. Do you recall which switch it was?

All the ones I've tried have a toggle that rotates in the switch such that the flap handle will not stay horizontal. -------- RV-6 RV-7 Flying Read this topic online here: http://forums.matronics.com/viewtopic.php?p=478900#478900 ________________________________ Message 8 _____________________________________ Time: 06:13:42 PM PST US From: Art Zemon Subject: AeroElectric-List: Voltage Regulator Damage? Folks, I am writing my POH, patterning it after the POH for a Vans RV-12. That manual has a warning, "Do not turn off the Master switch with the engine running except in an EMERGENCY situation. Running the engine with the Master Switch off may damage the voltage regulator." I have a Lycoming motor with B&C voltage regulators, LR3C-14 and SB1B-14. I have never seen a warning like in the RV-12. Is this something Rotax-specific? Should I have a similar warning in my POH?

Art: Rotax is RATAX... Forget about IT! Now, since you are flying a Lycoming the MASTER should be a SPLIT MASTER/ALTERNATOR. Automatically with a Split Master when you shut off the Master you also shut off the Alternator. If the Alternator (ALT) is OFF you removed voltage from the Field of the Alternator. NO DAMAGE will be done to the Alternator or the ACU. Barry On Tue, Mar 27, 2018 at 9:13 PM, Art Zemon wrote: > Folks, > > I am writing my POH, patterning it after the POH for a Vans RV-12.

Barry, I appreciate your thoughts but I have three separate switches: Master, Alternator, and Backup Alternator.

And if not now, when?" Hillel* ________________________________ Message 11 ____________________________________ Time: 09:38:40 PM PST US Subject: AeroElectric-List: Re: Voltage Regulator Damage? From: "user9253" I have an RV-12. A couple of years ago, my PC680 battery failed during flight with an internal broken weld, later found by Bob N. The battery was effectively disconnected from the aircraft electrical system just as if the master switch was shut off. No damage occurred to the voltage regulator or any other component. The symptom during flight was unstable voltage, swinging from too high to too low. You can read about it here: http://www.matronics.com/forums/viewtopic.php?t=16762906&postdays=0&postorder=asc&start &sid=5c9d8b0067c9a54cf7a0a3c0ea1ac72f I see no reason why an open master contactor during flight would cause damage to the voltage regulator. After all, the regulator turns itself on and off many time per second during normal operation -------- Joe Gores Read this topic online here: http://forums.matronics.com/viewtopic.php?p=478904#478904 ------------------------------------------------------------------------------------- Other Matronics Email List Services ------------------------------------------------------------------------------------- Post A New Message aeroelectric-list@matronics.com UN/SUBSCRIBE http://www.matronics.com/subscription List FAQ http://www.matronics.com/FAQ/AeroElectric-List.htm Web Forum Interface To Lists http://forums.matronics.com Matronics List Wiki http://wiki.matronics.com Full Archive Search Engine http://www.matronics.com/search 7-Day List Browse http://www.matronics.com/browse/aeroelectric-list Browse Digests http://www.matronics.com/digest/aeroelectric-list Browse Other Lists http://www.matronics.com/browse Live Online Chat! http://www.matronics.com/chat Archive Downloading http://www.matronics.com/archives Photo Share http://www.matronics.com/photoshare Other Email Lists http://www.matronics.com/emaillists Contributions http://www.matronics.com/contribution ------------------------------------------------------------------------------------- These Email List Services are sponsored solely by Matronics and through the generous Contributions of its members.
