On a 1985 model, the glow plugs are wired in parallel. One plug failing has no affect on any other plug.
If the fault detection system is working properly, the light remaining illuminated guarantees
at least four operating plugs.

Can you quantify "a long time?"
A common failure mode for the GP controller is short cycling. You might want to measure the amount of time the relay remains closed. With the engine off, you can easily hear it "clunk" when it opens.
