Troubleshooting 

Equipment Tests 

Page | 153 

Test #1:  

Observe the solenoid plunger without power to the loom. Tap on the 
plunger. Does it spring out quickly and easily? Does it stick in or move 

sluggishly? If it does not spring out easily, then you have a misalignment 
issue. Proceed to 

Test 1a

. 

Test #1a:   

Check plunger action of the surrounding hooks. If the issue is isolated to a 

single hook, the individual solenoid may be misaligned. Verify by comparing 
with the surrounding solenoids. See page 154. If the issue seems to affect 
several solenoids, you have a guide alignment issue. See page 154. 

Test #2:  

Observe the solenoid plunger without power to the loom. Tap on the 

plunger. Does the spring feel stronger or weaker than those around it? If so, 
you have a bad plunger spring. See page 157. 

Test #3:  

Observe the solenoid plunger in action. Does the solenoid remain activated 

when treadling a null pick, or never activate when it should? In either case, 
you have a bad solenoid. See page 161. 

Test #4:  

Observe the misbehaving hook at rest in center-shed position. Does the 

hook sit significantly closer to the upper knife than the others? If so, you 
have a bad plunger spring (see page 157) or a bad hook (see page 159). 

Test #5:  

Observe the rear most hooks at rest in center-shed position. Do the hooks 

clear the upper knife? If not, you have an upper knife alignment issue. See 
page 155. 

Test #6:  

Observe the misbehaving hook at open shed with all hooks down. Does it 

want to stay turned more than the other hooks? If you lightly run your finger 
drawing towards you along the short segment of the hooks, does the 

misbehaving hook feel stiffer/offer more resistance? If yes, you have a short 
segment crossover. See page 155.
