EGT expander trouble
I'm having trouble with my EGT expander when I instal both EGT and CHT probes to the expander. I have noticed that if I connect only the EGT probe to channel B I get a reading of about 22.5Cº, which seems to be right. but if I connect the CHT to channel A I get a reading in one chanell around. 0.5cº and 1Cº in the other. If I connect the EGT only to channel A I get a reading of above 1000Cº. Is my expander busted?

Hi Pesbra,
Could you post a photo of how you have EGT hooked up with channel A? And, can you confirm that you are logging channel A? Regards, Bill, for Eagle Tree |

Hi Presba,
It's a little hard to tell from the photos, but can you confirm that you have the orange lead in the middle connector, and the yellow lead in the outer connector? It almost looks like you have the orange lead in one of the outer connectors. Also, when you connect the CHT probe, note that you would then have two orange leads in the center connector, and one yellow lead in each of the outer connectors. Regards, Bill, for Eagle Tree |
