i have a hyster H50XM serial H177
this unit has an intermitent starting problem that sometimes it will not crank and only clicks.
the starter has been replaced and all of the relays check out fine. we have found that there is no negitive to the starter relay.
does this unit get it neg from the ECU? thanks!

Thanks for the help everyone. We checked all the grounds and tightened all of them.
To get the unit back into service we wired in an external splendid to supply a full 12 Volts to the starter on start-up.
Works great now.
Thanks again
9 out of 10 times its the ground. Pull all of your grounds including the ones under the floorboard clean them and reconnect them make sure your negative battery cable is good and doesnt have corrossion back up inside the insulation.
maybe try adding a prestart solenoid.
Sounds like a voltage drop someplace........if it just clicks then it seems relay is working, how is the battery did you load test it,cables in good condition? What is the voltage to the S side of the starter solenoid when cranking? Is possible the relay is dropping voltage also. Do voltage drop test for both positive and negative cables and load test battery.
The LPG machine is always a relay coil connected directly to the engine block grund
