I don't see how it could cause all three lights to light. I also don't know why it would say 3000 RPM and then 12000 RPM with no change in motor speed. Something is weird, but I have no idea what. Can you temporarily unwrap the tachometer sensor wire from around the spark plug wire, leave it hanging into space, and see if anything is different? It is at least possible that this wire is acting as an antenna, and radiating the spark plug impulses (very high voltage) into the ground connection, which could light the ground-to-neutral and ground-to-hot lights that are normally off. I don't have much faith in that thought, but I have no other.
Remember that two lit lights is correct for a household outlet or a campground power post outlet. But for an outlet on a generator, only one light should light. Two lights is NOT correct on a generator outlet. |
The meter looks to be the same one, except it has US Carburetion printed on it instead of Yamaha.
I grounded the generator to the TM and the weird RPMs went away: nothing plugged in = 3000, 100w bulb = 3000, touch the meter with nothing plugged in = 3000, touch the meter with 100w bulb plugged in = 7000. (That last one is still weird.)
The meter came attached to the metal framework (outside the generator - comment: not what I expected based on the web picture) that holds on the propane regulator and related stuff. Today I took it off the metal framework and unwrapped the red wire around the spark plug wire. With the meter and wires nowhere near the generator, I still got green, green, orange.
The meter is supposed to have a black wire grounded to the generator and a red wire wrapped around the spark plug wire. In that configuration, the RPMs are way too high, so the tech at US Carb told me to take off the black wire, and normal RPMs were observed with nothing attached. Now the red wire is no longer wrapped and if I put the meter near the generator it picks up the RPMs.
I think that if I rewrap the red wire to the spark plug wire and attach the meter to the plastic part of the generator that I may be OK as far as RPMs as long as the generator is grounded to the TM.
However, I still have the green, green, orange display.
