Check your wiring, especially connectors as the movement caused by hitting the machine can make the contact again for a short while,

Robinair seems to no longer support older models such as you're machine as it was built in 1991-2 and sadly it seem's not many people have kept there old manual.

Call or E.Mail Robinair or ask the dealer
you bought it from

Why would you have any product & no manual
& wiring diagrams

Can't work on cars that way,as you know

It is the solenoid with the pink wires

This is a common problrm of Robinair 34700Z / 347002k & 347112k series machine.so don't worry just do the following :- 1# Verify the ISV tank is not overfilled.if full,remove refrigerant manually from tank. 2# Verify if there is high pressure in the tank.Purge excess air from the tank manually.( Open air purge hose from the tank,then press tank valve as needed) 3#Check the high pressure switch for proper operation,if not then replace high pressure switch.Hope this will solve your problem, if so please vot for it

You can try to get it only from any Robinair service center, No one can post any Robinair service manual at web site because of copyright! If you wish you may check my other solutions which i've post earlier for the same problem.
Yellow wire marked with 67 is a ground wire & you can hook-up anywhere in machine body
