Well, it is really your choice to not use the optional switches, and not having the back-up/emergency functionality. However, on one hand, that's not what the factory (Aircraft Extras) recommend. On the other hand, have you considered what will you do in the following occasions?: - you are doing or practicing slow flight, with your flaps at the maximum deployment, and the FPS-Plus fails.

Please accept my sincere appreciation to all those that provided a wealth of information. The elastomeric puck was the failed part. I sent Drake Air my old part so it could be rebuilt. They charge $450 for this service. Aircraft Spruce does NOT carry this part. They carry the rebuild parts for a different drive coupling. I have attached some pictures showing the coupling and the engine removal. Again, Thanks to everyone for your help and support.

Carlos ________________________________ Message 6 _____________________________________ Time: 01:12:38 PM PST US From: Cleones Subject: AeroElectric-List: Questions?? Hi Bob, In the John Deere alternator and regulator frequently talked about here is the rectifier in the regulator? And, Is the alternator generating 3 phase AC ? And, about what voltage is the output of the alternator. Also, since we know that the # 5 terminal must be connected to voltage or the alternator doesn't work. I have tried this and it is true. Then what is the circuit like? And would it be a good place to connect the overvoltage crowbar to? Enjoyed your lectures at Bloomington recently. Cleone ________________________________ Message 7 _____________________________________ Time: 01:18:41 PM PST US Subject: AeroElectric-List: Tach pickup From: "N777TY" I'm wiring tach pickup wires to a switch that selects which mags gives the tach signal. This switch is right above the two mag toggle switches. Since I'm using EIS 4000, they say to wire from the P-lead through a 27k resistor to the tach selector switch. Any concerns with just using a small pigtail off of the P-lead wire at the mag switch (going into the tach selector switch)? I'd prefer not to run another wire all the way to the mag itself just for tach signal. My concerns here are noise and functionality (eg. to ensure it works as wired up). Also, any concerns with running the P-lead shielded wire together with the rest of wires, or should I find a separate path and firewall penetration just for these two wires? PS. Why does 20AWG shielded wire's inner conductor appear to be thinner than regular 20AWG tefzel wire (measured diameter including insulation)? It looks the same to me as 22AWG tefzel wrapped in shielding (and my stripper won't strip it at 20AWG setting). Thanks!

No. Run them together with other stuff as long as shields are grounded as shown above. >PS.

It looks the same to me as 22AWG tefzel wrapped in shielding >(and my stripper won't strip it at 20AWG setting). Maybe because it's not 20AWG wire but 22AWG. How do you come to believe that it's actually 20AWG wire. If there's a mil number on the wire it will looke somethign like 22759/16-20-9 where 22759 is the base spec. Slash 16 is the sub spec. 20 is the AWG and 9 is color. If there's a third dash number then it's the stripe color.

I like the simplicity of it very much! :) Wish I found this drawing before drilling a hole for the selector switch... but no biggie, the hole can be filled. I do have a quick follow-up question -- the drawing I was using (toggle mag switches with start button) call out for 20 AWG shielded wire for P-leads... This drawing calls out for 18AWG shielded... Any concerns with using 20, which I have on hand? Or should I be ordering 18? As for size of the wire.. I got the 20AWG shielded from B&C... Found the numbers on it and they read: M27500-20 TG1T14 So I guess it is 20AWG.. but again.. I gotta use 22 setting on the stripper to strip it.. Thanks again!

No. It is single phase AC. There are only two wires coming out of it. > And, about what voltage is the output of the alternator. It will go up to about 200 volts open circuit but when loaded it will be in the vicinity of 15 volts depending on how you measure it. > Also, since we know that the # 5 terminal must be connected to > voltage or the alternator doesn't work.

Cleone I interupt the wires into the regulator. In the past Bob has said that either into or out of the regulator will do the job but I wanted to be able to cut power to the regulator in case it was overheating or internally shorted. The regulator uses the battery connection to turn itself on and to sense the battery voltage so that it can regulate to 14.4 volts nominal output.

The MIL spec for the shielded wire I've been using and which seems to be commonly available is M27500. The insulation is thinner than 22750/16. I haven't seen shielded wire with 22750/16 conductors.
