What should the ELD voltage reading be with nothing plugged in? Mine is reading 5 volts...want to make sure this is normal before I go through the trouble of volt metering my wideband output.
Thanks.

What wideband are you using?
on the bench with nothing connected it shows 4.55V

PLX
I'm having issues with my wideband showing below 12.3 afr. Trying to narrow down the cause

So how does this work? Reverse voltage reading or something? Do I need to start playing with voltage offsets to get my WB to read below 12.3 AFR? PLX says they're not required so something is not jiving...

voltage offset is used to match the reading from the wideband display to the datalogged value.

So no.
Can you answer my question? Is the ELD voltage right?

How exactly do you have the wideband connected?

0-5 volt output from the SM-AFR box connected to the ELD pin.

Power is coming off a spare switched spade connector in the fuse box, ground is one of the screws used to attach the hood latch. I've tried another power source and got the same results.
