Is there an approved method of checking through a 110v DC control supply using a multi-meter?
I normally check with one lead of the meter connected to earth, and check for voltage at various points throughout the circuit, but an engineer at work says this is not the correct method.
Does anyone...
A small single phase 240v 50 Hz submersible pump motor runs slowly from starting, & quickly becomes overheated.
There is an 8 microfarad capacitor connected. Any thoughts on how to test this motor with a Megger/DVM?

Does anyone have any circuit diagrams for the above crane?
The crane is over 40 years old, and has long travel,cross travel, and fast and slow hoist. The problem is the slow lower function is not working,the thrustor energises but the brake and lower contactors do not energise.
Thanks
