Yes, I concur. I have the alarms on the EFIS, and not the EIS which is buried.
The VP-200 handles all the annunciations and electrical alarms.

Some background. As I was building.........I was worried about the CG being
to far forward and thus I was not concerned about putting in a bigger
battery (Odyssey 925 at 24 LBS) and my O2 system behind the rear bulkhead.
In the end, that left my empty weight CG at 109.22, which is pretty far aft.
My first annual is due in Jan and thus I am considering options for moving
the CG forward. I have a little more interior work to do, but I do not
think it will have any affect.
One of the options I am considering in moving the battery from the normal
location behind the bulkhead and mounting it on the firewall. My rough
calculation is the empty weight CG will move to 107.58 a little forward of
the forward edge of the envelope. (this does not include some of the wiring
changes which will also move the CG a little forward also.....).
So here is the real question, anyone flying out there with just one PC680
battery? If so have you found it adequate? I am a little like Tim
Taylor....why use a 680 anmp battery when you can get a 925 amp battery, but
do I need all of that power.
I have a standby alternator (8 amp) and a backup battery for my Alamo
instruments (AS, Altimeter and ADI). So I am not to worried about the loss
of the primary altinator
Anybody have any other ideas?

If it works for your CG, another option is to use two identical but smaller
batteries, one aft one forward. These would replace your one big battery
and your small backup battery. Run them in parallel for normal ops, split
if you have an problem on one side. PC-625s are more than adequate for
starting. My normal maintenance is to replace one battery every other year.
The old ones end up in law tractors and such - still going strong years
later.

The torque will be in your maintenace manual. If it is different it will be
indicated as such. Don't forget your maintenance overhaul manual composes
also of SB, SL and SI. as stated in the front of your maintenance book.
-And when you do your mags repair don't forget section 8 of the unison/sl
ick- manuals. Otherwise you really are experimenting. Right Tim.

Thats what I need but don't have one yet...figured
someone on the list may have one at their finger tips.- I wasn't sure I
would want to use the standard torque since the stud is in Al housing. Othe
r
folks are checking so if I hear from my local builder friends I'll let you
know.
Thanks

ear nut torque
You can look in the Engine Overhaul Manual if you have one and
if it isn't specified then you use the general table of torque values for
the
engine. -I have one, but don't have access to it right now. -I'll
look later if someone else hasn't already helped you by then.

Rene,
I have 2 PC680 batteries in my RV10. One is for the main bus and the other
is backup and for the EFIS to boot on during start. I can switch in both
batteries for start if needed. My experience has been that 1 PC680 starts my
RV-6A just fine, but it's not really enough for the IO540. It will start it
but sometimes I have to use both batteries when it is cold and it still just
barely gets it started. I'm using a skytec PM starter, so I different
starter might help.

Skytec PM starters have about the highest current draw out there. The NL
series takes maybe 10-20% less, and the Kelly E-drive takes about 1/2
the current of the Skytec PM.
