charging guage issue
hey guys. i need help with my charging guage. when i start the engine
the glow plug relay cycles on and off as normal. my charge guage goes
up and down when the relay cycles on and off. the guage returns to
14 volts after glow plug relay is done cycling. i replaced the battery
cables and starter relay. what else could cause this thanks alot

yeah,and Dave just explained that cycle to me the other day.
after the WTS light goes out,there is a short time where you hear the relay clicking,well what this is,is keeping your gp's warm,waiting for you to start the engine.thus the reason durring this time,for the volt meter to bounce up/down cus its sending that high juice to your gp's.
so really,to help keep your cranking power/battery life,it then appears logical to start the engine right away to get the batteries charging once the WTS light goes out.
but in short.like Dave says,its normal.so run her.

that is your trucks way of saying "hey i work fine!" If it wasnt clicking at all then you would have a problem. Any issues starting?

I am used to gassers and I was not happy to see that at first, but you get used to it.
