Hello everyone! My Gretz pitot heat isn't working. I'm a pilot, not a builder, so my electronics knowledge is lacking and I'm hoping someone can point me in the right direction.
With the heat switch on, I'm getting voltage at 12+/12-, but not at P+/P-. It was working until recently. The LED temperature indicator lights still work when the pitot heat switch is turned on. Does that indicate a problem with the control module? Should I just buy and install a new one, or is there a way to repair the CM?
Any input would be much appreciated!
