On mine max rich is around 1.0 volts, mids scale gives me
around 0.45-0.6 volts, low end drops off around 0.1.5 - 0.2 volts.
Thanks Ed. That is, of course, exactly what it should read.
The next step is to temporarily re-install the old mixture gauge, and
compare it to the EM-2. I will also measure the O2 sensor voltage at the
same time. I may even pick up another O2 sensor, just in
case.
Is the O2 sensor you are using a heated 3/4 wire
unit? If so I am wondering whether you might possibly have a ground loop
feeding heater voltage onto your sensor lead?
Good
thought, but it's just the cheap single wire unit that Tracy and Finn are both
using.
Thanks,
Rusty
