New Holland TC33d, Injector Heaters

I have a New Holland TC33D tractor and have been noticing the orange dash light indicating the injector heaters are on prior to and during the starting is not coming on. Sometimes when I turn the key it does just as it is supposed to, most times not any more. It's getting cold and I need the injector heater to engage.
Any thoughts? Relay? I replaced the inition switch already. I will look for loose wires.

SA,

When you go to start but the light doesn't come on, how well does it start? Trying to isolate whether it's a wiring issue to the light or the whole thing.

TC33D Starting Problems

Could be a bad relay or a bad indicator lamp

The relay suggestion was correct. It was not the cheap ($14.00) starter relay but the heater timing relay for $68.00. I changed both to be sure one did not accest the other.
Thank you!

The relay suggestion was correct. It was not the cheap ($14.00) starter relay but the heater timing relay for $68.00. I changed both to be sure one did not affect the other. It starts great now. I also added a block heater as well.
Thank you!

There are glow plug relays on ebay for a pretty good price. See KUBOTA NGK GLOWPLUG LAMPTIMER S81NL PN/ 15694-65990 for $21.95 free shipping. Folks on Tractor ByNet claim that they will work on the New Hollands as well.
