Measure resistance from the power supply's ground 
strips (EE) to the conductive contact in the center of 
the power supply seal (FF). See F

4.

The resistance should be 55-70 megohms. If out-
side this range, replace the power supply. If in 
range, proceed to the next test.

1.

Insert a conductive rod (GG) into the gun barrel 
(removed for the power supply test) and against the 
metal contact (HH) in the front of the barrel.

2.

Measure the resistance between the conductive rod 
(GG) and the charging probe socket (CC). See F

12. The resistance should be 15-30 megohms.

3.

If the resistance is outside the range, replace barrel.

4.

If resistance is in range, reassemble the gun and 
test the gun resistance.

5.

If you still have problems, refer to Gun Repair on
