Posted: Wed Dec 12, 2012 10:08 am Post subject: Z-13 Using PP Alternator

I have the  Plane Power 60 Amp alternator in my RV-7, which is about 95% complete. I do not  have an electronics background, so I question as to whether or not I have wired  my airplane correctly. I am using the AeroElectric Z-13 diagram, but the Plane  Power 60 amp alternator has an internal regulator, and built in crowbar  overvoltage protection. Therefore I have modified Z-13 to eliminate the external  regulator. Can anyone tell me if my modified diagram looks correct ? If not,  what needs to be changed to enable my electrical system to function correctly  ?   Any assistance is appreciated. 

Thanks,   Larry  Elliott,  N422LE

I did mine in a similar way with the red wire, but I didn't use the white wire.  Are you sure that illumination of that bulb means low voltage?  I was thinking it was a more general fault light.  I used Bob's other little low voltage warning circuit for the crucial low voltage role.

Larry,

 Minor point.  You are missing a power source  for the main battery contactor.  Connect point "I" to point "S" on your  diagram.

   Good catch. I agree that incorporation of the PP product

   into Z-13 is correct. I also suggest that the alternator

   inop lite built into the PP product be suplimented if not

   replaced by a dedicated active notification of low voltage.



   Eric has some product. I'll have some product again soon.

   If you're of a mind to roll your own, you could consider

   How ever you achieve it, independent notification

   of bus voltage below 13.0 volts is a really good

   idea.
