CORRECTIVEACTION
Reset brush motor circuit breaker (50 amp).
1.Clean battery cable clamps and battery terminals.
2.Check voltage at points A and B. Voltage should be 22/26 VDC.
1.Check voltage at points A and C. Voltage should be 22/26 VDC.
2.Turn main switch on and check voltage at points A and D. Voltage should be 22/26 VDC. If no voltage remove leads and check switch for continuity,
With main switch “ON” check voltage at points A and E and A and F. Voltage should be 22/26 VDC. If no voltage at A and F remove leads and check micro switch for continuity. Should be continuity in normal position and no continuity when switch lever is activated.
With main switch on (solenoid energized) check voltage at points A and G - voltage should be 22/26 VDC. If no voltage replace solenoid.
Reset vac motor circuit breaker.
Check motor lead connections at terminal block and inline connector near vac motor. Keep all connections tight.
With main switch on check voltage at points A and H and A and I. If no voltage, check continuity of circuit breaker. Replace as needed.
Remove leads and check switch for continuity. Replace as needed.
Check motor brushes. Replace when worn to W8“.Check vac motor by securing motor and applying 24 VDC to motor leads. No load amp draw of motor should be 15 amp.
Reset (50 amp) brush motor circuit breaker.
Check motor leads at terminal block connection (located under right hand lower side panel) tighten set screws as needed.
With main switch on check ouput voltage at points A and G. 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 direct to motor. No load amp draw of motor should be 12 to 13 amps.
Reset (6 amp) battery circuit breaker.
Check for loose electrical connections at terminal block, solution switch, and solution light.
Remove light and apply direct battery voltage (24 VDC) to light. Replace light as needed. Adjust solution light switch.
Check (6 amp) battery circuit breaker. Reset if tripped.
1.Check electrical connections at circuit breaker.
2.Check voltage at inline connector at PC Board. Should be 22/26 VDC.
