New Holland TC30 Starting Issue

Went to use. First thing the glow plug light would not come on, would not crank and no alarms.

Battery, Ignition switch, Safety switches all checked ok.

Installed the new safety switch and used the tractor for a couple of days. Parked tractor Saturday, went to start Tue and same condition as before. No Glow Plug Light, No Warning Buzzer, No Start.

Checked the wiring at the relay. It has four Wires, Red/Black, White, Yellow/Red, and Solid Black.

The wiring diagram I have shows the:

The Red/Black tied in to B/W from ignition switch and has power when key moved to start position.

The White wire shows going to starter.

The Yellow/Red Wire goes to multiple places.

The Solid Black wire appears to be a ground.

If I apply power to the Yellow/Red wire, the engine will crank but not start.

Any ideas.
