I have the Challenger Efis On the display the GPS has a big red x on it. I can't find out why. I thought it was because the plane was in the hanger but I took it outside today and the red x is still there. Still trying to get everything lined out. Help please.

Thanks Ranier I did the ground thing and found that I was not getting a good ground. These Stewart Warner floats do not have a dedicated ground screw like the VDO ones did. I was relying on the mounting screws for a ground. 3 of them worked fine but there is always one in the crowd as they say. I fi...

HI Could use some help here. I have been trying to get my fuel levels to read out on the EFIS> I have the 10.5 Challenger. I have 4 tanks. Two on the RDAC one and two on the RDAC two. I have replaced all the float sender units with Stewart Warner floats. They all work but the right side inboard. It ...

so are you saying I need to set up a virtual tank in the screen designer? If so can't do it. I don't think I have any real-estate left for another tank.

Hi Can anyone tell me if its possible to set up virtual fuel tanks when you have four tanks. I have two RDACS, two tanks on one and two on the other. Adam made me a custom screen to show the four tanks. I can't get them to read correctly with the RDACs. Is there a way to set up the flow (RED CUBE 60...

Hi I could use some help setting up my RDAC. I have two RDACS hooked to the MGL Challenger EFIS. I have two because I have four fuel tanks. So everything engine related is on RDAC 1. I had a custom screen designed so that 4 tanks show up on the screen. I can see all four tanks. But the problem is I ...

Yes

Success at last. that was the problem. Had to put the ground in the analog input plug. Wow one more problem solved. Thanks for the help everyone that replied.

Hi hpmicrowave. First off thanks for replying. Your setup looks almost like I did. Except mine is for pitch trim and they recommend analog 2 for the input. (I think that's right without looking it up ). I also have a relay deck and I have the orange wire going to 12 volts. The only difference is the...

Hey Everyone I have to admit I'm not having much luck with the MGL EFIS. I guess its just beyond my pay grade so to speak. My current problem (one of many) is getting the Ray Allen pitch trim display to work. The trim itself works from the china hat on the stick. I have 3 wires that used to go to th...

Hmm Maybe that's the deal. I haven't flown the plane yet. Just trying to get everything set up. When I boot up I get the low voltage flashing in red in the middle of the screen. pushing the acknowledge turns that off but my light stays on. So maybe I as your saying just canceling the audio and I sti...
