usually, diesels have two battery ... for 130 amps of cranking power, and heating the coil as well as the fuel heater.
ALSO ... you must use diesel battery power, not regular car battery, as they will need replacing in 30 days if you do.
with Fords ... you MUST have good quality battery, one cell out of the 6 cells for example being dead, is not good enough. all of them have to be up, gas or diesel.
sumbuddie hopes this helps.
PS // if you have Ford Turbo Diesel, your glow plugs are powered by 115 volts, so messing around with them wires will light your ass up big time, so be very carefull ... even think about using a professional certified mechanic for this part.
sometimes just putting in a new set of glow plugs is all you need for diesel ... the 'tuneup' is replace the fuel filter, that is it.
