I'd like to tell a quick story about successful troubleshooting.
A few months ago I rented a scissor lift to install lighting at my new office. When it arrived, the delivery person gave me a quick demo and off he went.
Well, when I went to actually use it - the lift went up by about a foot then stopped and screamed beeps of terror. It was broken!
But the display on the control read "18"
Rather than call the rental company, I searched "sinoboom fault code 18" to see what that meant.
@TechConnectify the first thing to teach in troubleshooting is to ask has this ever worked before? If no, is everything connected? If yes, what changed?
