I did check for voltage at the G/Ps, when I was trying to figure out how they worked, but I didn't really pay attention to "how much voltage" was there. It could have been lower than battery voltage ... I'll have to verify that. Also, I was thinking, I might put a temporary jumper from battery to glow plugs and leave it in place for a few seconds, after the engine fires, to see it's effect.
Oops, I see above where you did say it starts better with the glows than without. You'll get voltage lower than battery, to some extent. Possibly even as low as 6v, depending on the glow plugs used, and any inline resistors. But as long as there's voltage there, you should be OK. It's just a smokey starter. It might improve as the hours go up.
