Hi Mike,



Haven't heard from you in a while - are you going to be at the LAA Rally this weekend?

How's the Ez coming along?

best,

 



Bill

 I'm finishing off my electrical system in a Long-EZ that includes the SD-8, exactly as per the Z13/8 and have to make a final choice of the main alternator.

 

 For cost and availability locally I've decided to go with either a Lucas 60amp or 70amp. The advice I'm seeking is regarding the regulator, these units have an internal regulator, so do I keep the internal regulator? (remember the Z13/8 has the OV protection between the regulator and the bus) or do I do a conversion to use a B&C external regulator (I have a spare one I could use).

  

 I've read many, many threads on OV and runaway alternators etc. and am not too sure if using the internal regulator in the Z13/8 architecture will give me complete protection.

 

 Regards

Hi Mike,

     

     You do know that on this side of the pond, Lucas is known as 'The     Prince of Darkness', right? 

     

     Internally regulated alternators and their OV protection scheme have     been deleted from the current version of 'the book'. But, if you     eliminate the separate 'aircraft style' separate switching of the     alternator, then you can use Bob's OV module to control a separate     contactor, in series with the B lead.

     

     Bob & I had a recent discussion about this very issue, titled     something like, 'the question that won't die'.

   First, why so large an alternator? Can tolerate or do you NEED that

   weight aft?  I've seen a lot of EZs with oversized batteries up

   front . . . not for energy contained but for ballast. If you NEED

   ballast then it might as well be useful ballast.



   Can you put your hands on an Nipon-Denso alternator

   in the 40A class? This is probably MUCH more power than

   you'll ever need and among the lightest of options. What

   ARE your energy requirements? Have you accomplished a load

   analysis? Keep in mind that the SD-8 series alternators are

   products that BIRTHED B&C Specialty Products when Bill

   delivered to a request from Burt Rutan for a lightweight

   MAIN alternator.



   There ARE ways to live with a built in regulator in ANY

   of the Z-figures . . . let us first thrash through

   the ideas and facts that drive real requirements.



   Give us a list of electro-whizzies you've installed

   and what their CONTINUOUS current drains are . . .

Yeah; sorry 'bout that. I didn't mean to stimulate the retelling of 

*every* joke about British tech. Besides, the Brits have done lots of 

stuff first, or better. The jet engine, for one. And if you've never 

flown a Chipmunk, you need to. I don't think anything flew as well until 

RV's came along.

Sometime in the mid 1700's the French invented the toilet seat.

 After 75 years of use, the English greatly improved on the French design by  cutting a hole in it.
