(ET) brake switches...

["Dave Barden" <daveb seanet com>]

A while back I ordered a brake switch for the E12S from Bill Gunn.  Today I
finally got to putting it on, only to discover that is configured 180
degrees out from the original.  Meaning that when mounted the lever misses
the bolt on the brake pedal and the wires are handging down below the 
switch
and smashed into the frame.  Before I call Bill on Monday I thought I'd
check and see if anyone else has had this problem.  Did the manufacturer
goof?  Is the brake pedal on the right side on some models??

thanks,

My preference?  Set it up for 42.5V+.  36V is not fully charged.  Again,
here are the SETTINGS ON THE FUEL METER OF THE ET!  (numbers courtesy Steve
Naugler)

1.  Needle just moves = 20 to 22 VDC.
2.  Bottom of red = 27 to 28 VDC.
3.  Top of red = bottom of green = "E" = 35 to 35 VDC.
4.  Top of green = bottom of white = "F" = 45 to 46 VDC.
Note:  Green zone is the normal operating zone.
5.  Top of white = bottom of upper red = 52 VDC.
Note:  White zone is the charge zone.
6.  Top or upper red = 54 VDC.

NOTE!  36 V is barely off the RED!

42V is LOW on the green

48 V is (DRUM ROLL!) in the white or CHARGING region!

Personally, if I know I have a lot of work to do I will charge well into 
the
white.
Disconnected, within an hour it always drops to about 43 to 44V MAX and 
42.5
is nominal after 1 day just sitting.  This is the 'charge' level of my
batteries.  ours may differ, but not by much.  Beyond that and you are just
gassing.

Sure, the ET charge load WILL drag the 48V system down, (and remember, that
'48V' system may be 52V for all I know...) but the only risk is gassing of
the batteries if you charge too long... exactly the same risk as charging
too long with the ET charger.  In addition, I suspect the 48V system is
probably reasonably low current;
lower than the ET charger.  If you had too, you could set up a simple
circuit with Zener diodes or regulators to protect it, but I don't think I
would bother.  Just use a working ET gauge.
