81418784532&item=281418784532">G1900 Kubota, the glow plugs are energized when the keyswitch is moved halfway to the start position. Also the glow plug indicator light is illuminated when in this position. I hold the key in that position until the glow plug light goes out, and then crank the engine. On really cold days I repeat the glow plug cycle several times before cranking.

The wire that runs to the glo-plugs comes from the relay and as it is a heavy gauge wire (colour coded ) try tracing it back to a relay. IT may be completely separate to all the others.

The relay is in easy view on the top of the motor, a little to the right side (passenger side). You will see two identical relays. One of them, the large battery cable goes to the intake air heater. The other relay is for your glow-plugs.

Does anyone know where the 2 glow plug relay our on a 2012 Nissan cabstar ?

Glowplug relay 180; located in Position 10 in the relay panel. If you unplug the coolant temp sensor, you can trick the computer into thinking it's really cold out, and it will run the glow plugs.

The glow plug relay is placed inside car on the fuse box & relay plate - fascia 2. The glow plug relay is no.# 4. See pictures below:

The first thing to do is locate the owner manual.

Look for the glow plug relay MAIN FUSE location.

The glow plug portion of your van is not working.

This difficulty scale from 1 to 10 is a 9.

You will need a DVM and tool undo the cables to each glow plugs.

It's a 1 to 2 hours troubleshooting job.

I'm going to fire off a quick list

====
Check / replace blown glow plug relay main fuse
====

Disconnect each center nut of the glow plug wire. PLEASE CHECK ONE AT A TIME.

Read the resistance between the center of the glow plug and the metal base of the plug.

Please take good note on each glow plug resistance reading.

MAKE SURE all cables are put back and tighten properly.

Compare the resistance on all cylinders.

OPEN/high resistance is bad glow plug.

In general 3 ohm or less is OK.

You should buy one and use its value as baseline.

Glow plug relay can be bad.

You will need the VOM and a friend to turn the key.

Check the voltage to each glow plugs. It should be 12.6-13.6 volt.

Be careful,the plugs will get HOT.

Compare the voltage on each cylinders.

====
So the problem can be combination of

glow plug relay

glow plug relay main fuse

glow plugs

ignition switch is unlikely but I'm going to list it anyway.

Once again,this is a difficult and time consuming job. I will ask a friend to help out,

Good luck.

Good Day
The glow plug relays are located on the right front shock tower. Remove the cover and you will see two relays If I remember I think they are round, but not sure.

Please let me know how you make out and if there is anything else that I might be able to help you with.
