electrical problem

[Kenneth Cole]

Good day
When I start my 1991 it seems that the glow plugs (if that is what is happening) cycle on and off for to long (several minutes) with the volt meter going from the red to the yellow and last night when they finally stopped cycling the volt meter stayed down in the red slowly dropping down to the bottom for about ten minutes before it finally went up into the green.
Need some advice as to where to start with this problem.

Thanks
Ken

NORMAL with some of the older PCB "protective control box" to cycle the glow plugs until engine is warmed up.

Search THIS FORUM for Walmart 24F batteries with "northern" manufacture. There are a few threads about this as far as good batteries.

NEVER WORK ON YOUR TRUCK WITHOUT DISCONNECTING THE BATTERIES!
