The older Haynes manuals have an internal diagram of the temp sensing unit. I have a unit that I believe works as it should. The problem with the original unit designs is you never see the light until you are overheating. Later systems have the light come on with the key turned on.
I'll be out of town for a few of days starting today (4-11). I'll let you have this unit for free if you want it.
