[AT] IH B275 Diesel

[Bruce Fallon]

I believe you mean each glow plug has two terminals.  The glow plugs are 
connected in series with battery supplied to the first one and ground is 
connected to the last one.   I looked at the diagram and from the switch 
there is a resistor which will drop the voltage going to the first  glow 
plug from the 12 volts to the proper approximately  4 volts needed, 9/10ths 
of a volt times 4 plugs equals 3.6 volts. These will work like cheap 
Christmas lights if one goes out they all stop working.

These glow plugs do not ground through the threads.

You guys don't get it, each plug has two circuts and they don't ground 
thruthe threads and the last plug is grounded to the block...
