    When you say “no start” do you mean “crank, no start” or “no crank, no start”.? Sorry should have read your text better - it’s no crank, no start. What have you checked so far.?

    Open the pdf file with pdf reader software and then use the zoom function or press the control key + mouse roll wheel to enlarge it.

    I started out cleaning grounds, then went to batteries, I found a cable between two batteries that was not getting a good connection.cleaned up connection and got it running but still need to install new cable. today the swing function stopped dead in its tracks, so tomorrow I will install new cable then look at why the swing function stopped

    would I need to look at the swing brake solenoid, could a low voltage problem mess with this ?

    part number is 121-1491 looks like there are three of these in the valve stack having a hard time identifying the swing stack?
