Board Repair Cobra 29

I found an old cb repair cd that I forgot I had from a company in Chicago and it states in the transmit repair section:

Is there a signal of 27.185 MHz at TP4?
Next
Two possibilities here. IC3 is still not working or L20 is open or very much out of alignment. Not much choice. Suspect an open L20 if the signal is present at Pin 9 of IC3. Try tuning L20


I tried tuning the can and nothing with it in or out, so I supect this is the culprit.

My question is I have some old radios and can swap out the can, but to properly test it, is it done with ohmeter?
