855D Turns overs but wont start

My 2010 turns over slowly but wont start. It appears to have a starter relay module but not sure how to test and if anyone has had problems with this.

I have spent hours checking all wirings/grounds/connections....all good. It now has a new battery.

It cranks over slower than normal, dash lights dim, hydraulic box lifts very slowly.

I have 12V+ at starter solenoid but when I check the trigger wire for the solenoid it showing low voltage with ignition/start switch engaged.

After many start attempts, no smell of any diesel...weird.

I keep coming back to starter relay module as possible source but not sure.

Any comments appreciated.

I think you have a grounding problem. Measure between battery negative and engine block. Should be about 0 volts. And you should start the engine during measurement
