No power to high pressure options

[shineanddrivevulcan@gmail]

In one of my bays i am having an issue with the high pressure options. Low pressure options work along with vacuum but when I switch it over to the "soap, rinse or wax" nothing.

Please walk me through how I can trouble shoot this issue so I can avoid a callout. I have checked the fuse that leads to the motor and its not tripped.

Any assistance would be greatly appreciated

Do you have a basic understanding of how the system works? And how to troubleshoot electrical circuits? Probably not a good troubleshooting job if you are a rookie, that's high power electric

Do you have a voltmeter? You'll need a voltmeter to trace back to find out where the problem is. I'd start with the motor contractor.

Start with turning on the bay and looking if the motor is running. If it is then check and see if the belt is broken to the pump. If the motor is not running then locate the contactor and overload. The overload may be tripped. You will need a volt meter to test power on the incoming and outgoing legs of the contactor.

great advice

first thing i usually do is open electrical cabinet and manually push motor conactor in to see if motor activates.
