what is it that clicks under the dash that the volt guage jumps with on each click? and where can i get a replacement? its seems to be a relay that is shorting or just going bad on the 12v side for the alt.

glow plug relay is what clicks when i move my plow and volt drops? it is under the dash on the left side.

ok the more i read on the gpr the more im getting confused. the clicking happens when i put the lights on use the heater and the plow. red gen light will come on hear the click than volt drops. has newer rebuilt alt that is pulling 12-14v at idle. has new belts. and new 12v battery. this click comes even after the truck has been running for an hour or more, so it is definatly warmed up. kinda new at the military trucks so short word terms are not something im seeing in the search area.(like tm has everything????)
