milotron Posted August 30, 2017 Report Share Posted August 30, 2017 Hi, Haven't flown in the dark in a couple of months and just plain don't remember or didn't notice; Is there any backlighting to the fuel/oil/temp/ammeter gauge cluster or is it front lit from the the glare shield? Schematic diagrams suggests that there is not. iain Quote Link to comment Share on other sites More sharing options...
KSMooniac Posted August 30, 2017 Report Share Posted August 30, 2017 It is all from the glareshield light strip.Sent from my LG-US996 using Tapatalk 2 Quote Link to comment Share on other sites More sharing options...

flyboy0681 Posted August 30, 2017 Report Share Posted August 30, 2017 On my '83 J the cluster is back-lit. 1 Quote Link to comment Share on other sites More sharing options...
milotron Posted August 30, 2017 Author Report Share Posted August 30, 2017 I should have thought of that...my manual shows the same thing also. I'll need to look into this some more I suppose. Looking at some pics, mine looks like that in the back too. Will pull the glareshield and more troubleshooting I suppose. iain Quote Link to comment Share on other sites More sharing options...
mooniac15u Posted August 30, 2017 Report Share Posted August 30, 2017 In the M20J the lighting wasn't added until 1982. In my 1981 J the gauge cluster is the same part number as the lighted version and has locations for the bulbs but not the wiring to support it. It seems likely that the same is true for the M20K. 1 Quote Link to comment Share on other sites More sharing options...
milotron Posted August 30, 2017 Author Report Share Posted August 30, 2017 OK, I answered my own question. In the parts manual it notes that these are an option until a certain serial number. Quote Link to comment Share on other sites More sharing options...
