JPI EDM 930 auto dimming
I have an EDM 930 engine monitor that upon initialization defaults to 25%. Itís nearly pitch black and impossible to see outside. Itís supposed to default to 100%. I have sent the unit to JPI for a software upgrade( only option) and to fix the auto dimming. It worked for a bit. I looked at the installation manual and wiring pin diagram. I was hoping that I could reset the default without pulling the unit or to install a external dimmer thru the pins themselves. I did see that others had the opposite problem of going full bright at night but solved that with some tape over the sensor, lol. Iím hoping I donít have to send the unit back to them, plus they are closed until further notice due to Covid-19.
Thank you for any input!
