Finally near end of the refurb of my L2 into a L3. Time now to face the inevitable electrical gremlins.

Turn the key switch on and Tattletale II & II all function as they should work (lights don't light up). Push test button all lights work.

However when key switch is on the following lights come on hyd oil level (it shouldn't), engine oil pressure (it should), coolant temp (it shouldn't) and bin level (it shouldn't). Battery voltage and unload out don't light (and they shouldn't). Module isn't new but had it tested at dealer and checks out OK.

Anyone with any thoughts. Is there something simple (LOL) that I'm missing.
