I have a 01 cat 304.5 mini that i recently purchased will not start when cold out. glow plugs are not getting power from relay, have 12v to relay & yellow wire to glow plug is good, I would think there has to be another timer relay of some sort. does anyone have a wiring diagram for this machine, the control circuit for relay never has B+ to turn relay on.. THANKS for any info.

Not familiar with the minis but maybe a wiring schematic would help? See attachment.

Sound like you need to get a cat to protect that Cat! Glade the diagram worked.
