I couldn't wait to try digital odometer test:

but I found some disturbing output in the OIL mode.
in the OIL mode constantly read 000 while running and 255 while not running, although the dummy gage reads pressure as normal.

one explanation
I thought the test mode was reading realtime, bypassing the dummy gage wiring....
Anyone have any thoughts on this.

The oil is 000 because our oil pressure gauges are factory set to read mid-scale. There is a resistor wired to the back of the gauge board wired to a switch (the same one used for a dash without a gauge,just a light) on the engine that will only allow the gauge to drop if the pressure is below 6 psi.
