It sounds like temperature is a factor here so a cold solder joint or connection for example could reflect that.

Do you know what each pin is for or what each colored wire is for? The relay has seven pins total. I would like to test to see if I am getting 12V from the cord when I turn the ignition to glow. If I am not, then I can assume that the problem isn't the relay.

If the original Glow Plug system had a 50 amp strip Fuse on the Fire Wall or no Fuse at all (inside of the Relay is a Reed Switch that will disconnect when the Switch gets hot) I don't believe it can be used with that Relay.

I read somewhere that the old relay will work, but can burn out the plugs if the key is left on in the glow position for too long as the old relay doesn't have an automatic shutoff timer.
