I turned on the SD-8 aux alternator and the voltage increased to the low end of the normal range. I also noticed a whine sound in my headset. If I turned off the main alternator, the whine went away but the voltage sagged. (I have an all electric airplane and the SD-8 won't carry the full load unless I shed loads, turn the master switch off, and run on the E-bus.) I turned the main alternator back on and the whine sound in my headset returned and the voltage returned to the low end of the normal range. I flew that way for about 15 minutes and the whine suddenly stopped and voltage jumped up to normal. I turned off the aux alternator and completed the flight normally. Everything was perfectly normal for the two hour flight home. Any ideas what caused this? Since the first symptom was reduced output and a whine in the headset, I initially suspected failed diodes inside the alternator, but when it healed itself, I thought it might have been a brush problem inside the alternator. After 15 minutes, whatever was causing poor brush contact went away? I'm grasping at straws here. I am so thankful for Bob's Z 13-8 architecture, which allowed me to continue the flight without breaking a sweat! Thanks, Bob!

I ended up using only the Coolie Hat trim sw itch, the trigger for PTT and the paddle switch for flaps. In the end, I fe lt the risk of inadvertent fumble fingers activating/deactivating other fun ctions overrode any perceived convenience. However, other folks have utiliz ed all the switches very successfully. As with most things in the homebuilt world, whatever you think works best for you. ________________________________ Message 6 _____________________________________ Time: 10:34:24 AM PST US Subject: AeroElectric-List: Re: OFF-ON-ON Toggle switch? From: "dballin" If you want a Carling switch, I used Carling L52E166A77. It is a 24V light. If you need 12V just go to there website to configure it. The important part is the L52E. I am using it as a OFF-Low Boost-High Boost switch for my fuel pump.

Once I had to chase a mystery problem. Alternator would go off line, later come on line. I later chased down a hairline crack in the stationary stator windings in the case where it entered a swaging boss. When the alt. go hot, the hairline crack would open and after the alt. cooled a little the wire would make continuity and charge again. I suspect that the heavy wire was damaged during manufacture and would not show up until the alt. put under heavy loads in hot conditions. I had to use a magnifying glass to finally view the crack..... If it is not diodes, then look for this stator wire problem.
