2.Remove the power supply (18), page 46.

3.Remove the turbine alternator (19) from the power supply, page 47.

4.Measure resistance from the power supply's ground strips (EE) to the spring (18b). See FIG. 18..

5.The resistance should be 95-105 megohms. If out- side this range, replace the power supply. If in range, proceed to the next test.

6.Be sure the spring (18b) is in place before reinstall- ing the power supply.
