Multi-Quip Generator “no start”

Symptom : Generator ran fine when shut down, Went to start the next morning, the fuel pump would prime, engine cranked a few revolutions but engine would not start, subsequent tries would prime fuel pump but no engine start sequence.

 

Fix: Replace ECU fuse -15amp

Procedure:

  1. Remove  2 thumb  screws holding on instrument panel.
  2.  Locate  fuse holder *see attached photo Fuse(original fuse was a 15amp Buss Fuse)
  3. Replace  blown fuse with 15Amp blade fuse- If no fuse is available running the generator in diagnostic mode will bypass this circuit assuming all other parameters are correct.

IMT Knuckle Boom

The lights for the outriggers were not working.  Called IMT, we opened up the RCL 5300 which is the pad on the side with all the buttons, and found one of the wires 52, or 53, to be loose on the power side.  Took out and reconnected and all worked fine.

Warning Light on RT Mobile Crane

Warning alarm and beeper going off in cab.

Recalibrate length indicator and angle sensor according to PAT manual (found in mobile crane folder).  Light would still go off at restart, but after any movements, light would go off.  Scoped all the way out and then back in, and light has remained off.
