So - I'm mocking up my instrument panel on the workbench and fired up the EFIS and EIS for the first time. By accident I touched the master relay and discovered it was pretty warm, borderline hot. So I pulled out an IR thermometer and read 143 F. That seems strange to me but it might be normal. I wouldn't expect measuring the temperature of a master relay to be a normal thing to do, but just in case others have some sort of experience in the matter I thought I'd post the question. What's normal??
