Glow plug not working

[RWD123]

Good day

Have a couple issues but first issue trying to figure is why glow plugsare not working. Tractor has rebuilt engine with new glow plugs. Noticed in another thread someone posted a picture and in it shows two 70 amp Handouk relays. My tractor has both plugs but nothing is plugged in them are these for the glow plugs? Tractor runs fine once started. 60amp fuse is good and glow plug light comes on.

I see nothing about troubleshooting you've done. Do you have voltage at the glow plugs when the glow plug light is on? I'd start there. If you have voltage the new glow plugs may be bad. If you have no voltage you need to determine why.
