Hobbs Switch

[Ernie Martin]

Roger:

I looked today at the airplane and in my 337G the adjustment was to cut the lever to the proper size and then glue/solder near the cut end a dime-size disk we made from aluminum.

If you need to fly before you fix it, just connect the two leads together without the switch; in that configuration, the Hobbs runs anytime the master is on rather than at speeds over ~ 40 MPH (when the airflow pushes against the disk to close the switch circuit).
