Only on one pin and that is from the battery through a fuse
the rest will be dead until you go to start the engine in which case a second plug get power to close the relay points to allow power to the glow plugs
Your dip stick tube is your fill tube for your transmission . Make sure your transmission oil is at opperating temp before servicing some instructions are written on the dip stick , Use a small funnel , Add a little at a time (cup). Use the proper fluid , check regularly

the best way i have found to test glow plugs is to disconnect the wire to the plug and get you 12volt test light and put your negitive lead of the test light on the positive battery cable so when you touch the test light to any ground the light will light. so now go check your glow plugs and if you have one that doesnt light the light its burned out.
good luck

Have you checked the glow-plugs? On that system if one glow-plug is burnt up than it will not let the main relay in the controller to kick in.
Check all the glow-plugs make sure they are working.
The easiest way to check them is with a regular 12v test light.
Hook up the negitive end (aligator clip end ) to the battery + terminal and than with the other end of the test light ( pointed end ) touch each glow- plug connector tip ( with the glow-plugs harness connector removed ) and see if the test light lights up.
If the test light up--- glow-plug is good. If not than the glow-plug is bad--burnt out .
