Normal. You're measuring voltage drop across a resistance (glow plugs).

After I hooked everything back up, I measure the relay output again. The volt meter was reading 0v on the second go-around....first time it was measuring .7v.
I appreciate all your help and time. I know some mechanically inclined people that can give me some hands on explanation.
Just talked to an ASE mechanic, now he's confused
The way I'm looking at it, the glow plug side of the "tree" is a dead branch...not connected to any type of power source, since the negative cables are not connected. The "glow plug feed" side of the circuit is not suppose to have continuity with the + side of the batteries
until the GPR is engaged. Thats the way I look at it...
I'm going to do some research on automotive 12v systems and relays.
