lotsofgadgets Posted October 1, 2019 Report Share Posted October 1, 2019 Now that it is getting dark earlier i find myself using the panel lights more often. On my last flight I went to turn on the panel lights which also dims the Avidyne displays. No Click on the right hand knob , the panel lights don't turn on and the screens stay bright. The glareshield lights work normally. I am assuming the rheostat in the dimmer box broke. Does anyone have a source for replacement Rheostats, or do I have to look for a used dimmer?

carusoam Posted October 1, 2019 Report Share Posted October 1, 2019 The click is part of the switch... sounds like something isn’t working correctly... Great observation, that should get you to the next step... PP thoughts only, not an EE or mechanic.. Best regards, -a- Quote Link to comment Share on other sites More sharing options...

laytonl Posted October 2, 2019 Report Share Posted October 2, 2019 I would suggest moving to something like this. https://www.aircraftspruce.com/catalog/elpages/maxDimUnit.php Lee 2 Quote Link to comment Share on other sites More sharing options...
CaptRJM Posted October 3, 2019 Report Share Posted October 3, 2019 You can go with a MaxDim and get rid of the factory dimmers. STC’ed for Mooney. 1 Quote Link to comment Share on other sites More sharing options...
lotsofgadgets Posted October 9, 2019 Author Report Share Posted October 9, 2019 I located a secondhand dimmer assembly and swapped it. Everything works now. I like the idea of the MaxDim, but I couldn't justify $280+ per dimmer. Maybe by the time these rheostats go south there will be a more cost effective alternative.

jetdriven Posted October 10, 2019 Report Share Posted October 10, 2019 there are two small FM01 fuses at the back of the dimmer, those may be the problem Quote Link to comment Share on other sites More sharing options...
