TROUBLE-SHOOTING GUIDE

PROBLEM

PROBABLE CAUSE

CORRECTIVE ACTION

I

 

 

No power.

Battery cables corroded 1. Clean battery cable clamps and battery terminals.

 

at battery terminals.

2. Check voltage at points A and B. Voltage should be 22/26 VDC.

 

Faulty main switch.

1. Check voltage at points B and C. Voltage should be 22/26 VDC.

 

 

2. Turn main switch on and check voltage at points B and D. Voltage should be

 

 

22/26 VDC. If no voltage remove leads and check switch for continuity.

 

Faulty safety override

With main switch “ON” check voltage at points B and G, and B and H. If no voltage

at B and H remove leads and check micro-switch for continuity. Should have con-

 

 

tinuity in normal position and no continuity when switch is activated.

Circuit breaker tripped.

Reset vac motor circuit breaker (20 amp).

Faulty PC Board or

 

faulty light.

Check motor lead connections at terminals.

Remove leads and check switch for continuity. Replace as needed.

With main switch “ON” and vac switch “ON” check voltage at points B and I. Voltage should be 22/26 VDC.

With main switch “ON” and vac switch “ON” check voltage at points B and J. Voltage should be 22/26 VDC.

Check motor brushes. ReDlace when worn to 318”. With batteries fullv charaed and motor secured , apply ’battery voltage directly to motor. No load amp draw of motor should be 6.2 amps.

Reset circuit breaker.

Check motor leads at terminal block connections (located on inside front of frame). Tighten screws as needed.

Remove leads and check switch for continuity. Replace as needed.

With main switch “ON” and brush switch “ON” check voltage at points B and K. Voltage should be 22/26 VDC.

With main switch “ON” and brush switch “ON” check voltage at points B and L. Voltage should be 22/26 VDC.

Check motor brushes. Replace when worn to 3/8”. With batteries fully charged and motor secured, apply battery voltage directly to motor. No load amp draw of motor should be 6 to 8 amps.

Check for loose connections at solution light, solution switch and at vac fan relay ground.

Remove light and apply direct voltage (24 VDC) to light. Replace light as needed. Adjust solution light switch.

Check connections at battery card, micro-switch at charger Connection, and ground connection at vac motor relay.

Check voltage into PC Board (point T). Voltage should be 22/26 VDC. Check voltage across first pin (from right) and eighth pin (from right) point U. Voltage should be 8/10 VDC. If voltage is 8/10 VDC replace battery charge level indicator light. If there is no voltage replace PC Board.
