Test Power Supply Resistance
1. Prepare the gun for service as instructed on page
41.
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 F
IG. 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-
