If you have Third after using the CC / Power Pulse button, the
contactors the armature resistors and the 2AH relay are OK.There is an
issue with the connections between the 2AH relay's coil and where it's
shunted across the traction motor's armature.
If there is too much perceived voltage drop, 2AH prevents the
2A contactor from picking up.Pushing the CC button bypasses the shunt
long enough for the relay to pick up, allowing the contactor to close.

Hi all, Is
it possible to buy coils for an
I5? The switches on my foot pedal check out OK, but I only have the
first two
speeds, with 3rd and 4th unresponsive—although 3rd
seems to kick in if I use the cruise control option.
All for now,

There was much back and forth about batteries
lately, almost too much
for me to follow. T. Humphrey posted useful voltage numbers and the
fllwg
may also be useful. My T105's have 39 charge cycles (18 hrs per cycle)
using the oem charger:

In my experience, the onboard ge charger
takes my newish T-105's up to
44-45v over an 18 hour cycle, the last 3-5 hrs between 44.4 and 45v for
cell
equalization. End the charge cycle and in a short time the voltage
settles back to 39v.

I just got a nice new pack of Trojan T-605s (slightly lower capacity
than
T-105s, with a proportionately lower price). I'm trying to figure out
what the
voltage of a fully charged new pack *should* be, and I have seen very
different
things as skimming through the archives.
My understanding is
that the
chemical reactions taking place in a lead-acid cell produce a potential
difference of 2.13 Volts, so a fully charged lead-acid battery measured
with a
very high impedance voltmeter should measure that 2.13 Volts per cell,
or 6.39V
for a 6V battery, and 38.34 V for a 36V pack.
But, I have seen
statements in
the archives saying that a fully charged pack should have a voltage of
42V or
so (various posts saying anywhere from about 40V up to 44V).
Thanks,
Mike
