Off-Topic glow plugs

[Jeff Miller]

Okay, but in '87 they added "afterglow" to the glowplug relay
circuit to run the glowplugs after starting, much cleaner/smoother
idling cold. Wouldn't that be nice for the Perkins on a cold day?

It certainly would be. In fact, it seems to me that a simple separate switch
would solve this
problem. You could keep the glow plugs on as long as you wanted. Nice cars.
Tom
seemed to indicate that pencil plugs were available for the Perkins. Anyone
know where?
