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, Stewart Wells

pack voltage
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
