Glow spiral iseki tx1500

[iseki_guy]

Hi ! The glow eye of my iseki TX 1500 won't work properly, also the glow plugs won't heat up like they should.
I placed a new glow eye, new glow plugs and replaced the wiring Involved with the glow plugs and glow eye.
I also cleaned the threads of the glow plugs in the engine block because I thought it might be a mass problem.

Anybody here who can help me out trying to solve this?

I'm not familiar with your tractor, but you should have a glow plug relay somewhere on the fire wall of the unit. Someone with a like unit should be along. Did you check the spiral indicator for continuity with an ohms meter?

Yes I checked the spiral, also the wiring, the starter switch. When I preheat everything gets power.
Here is also the wiring diagram. It's wired like this. There is no glow plug relay.
