If your know a little bit about electronics you can fix your Bird 43 wattmeter should it become intermittent. Here are a few tips on what to do if your Bird 43 wattmeter is not working. Don't try these tests if you are not familiar with the electronics. You can damage your meter if you are not careful.

The Bird Model 43 Wattmeters are very robust and rarely fail. There is not a whole lot to them. Most of the electronics are in the elements, not in the wattmeter housing. The wattmeter consists of the transmission line section, a 30 ua meter movement, and a length of coax connecting the two. 99.9% of the problems I see are with the wattmeter contacts to the elements and the coax connector on the inside of the wattmeter to the transmission line section.
