| starter looks okay but is still suspect, | |
| you have two options: have a | |

| starter for function, or purchase a new | |
| starter and establish if that was the | |
| problem on changeout. | |
| If you have access to a voltmeter, you | |
Motor starter failure. | can separate a starter failure from a | |
motor failure by first, verifying | ||
| incoming voltage at | |
| second, checking the voltage | |
| between starter and motor at 220+/- | |
| 20. | |
| If incoming voltage is incorrect, you | |
| have a power supply problem. | |
| If voltage between starter and motor | |
| is incorrect, you have a starter | |
| problem. | |
| If voltage between starter and motor | |
| is correct, you have a motor problem. | |
|
| |
| If electric motor is suspect, you have | |
| two options: Have a qualified | |
