Good evening everyone,
I have been having problems with starting my tractor (Grand L4240) for a while and I am not sure if it's the cold weather or humidity that is causing it. I question if it's the humidity because everytime it has refused to start has been on humid days. I tested the glow plugs a few weeks ago with an ohm meter and they tested good. Today I decided to pull the plugs out and test each one individually to make sure they work and they all glowed fine.
After re-assembling everything, I tested the voltage going to the disconnect before the glow plug and the voltage was the same as at the battery. After reconnecting the disconnect and turning on the ignition, there was 0 volt at the glow plugs. Has anyone seen this before? Any ideas what could cause this?
Other than doing the above testes, I have cleaned and greased every connection I could find (at the battery, ground at the frame, at each glow plug) to make sure it is not a corrosion issue; I have checked all the fuses and they look fine; I also replaced one of the glow plug relays thinking it may be the culprit because one of the pins showed signs of overheating (blueish color). When I plug the block heater, the tractor starts fine.
The next thing I am going to try is to disconnect the temperature sensor to make sure it hasn't gone bad.
Thanks.
