no power to glow plugs

[linda ann]

79 300sd 116, glow plugs are about 1 yr old and still should be good, right? well upon checking it appears i am getting no electric(?) power to them. my baby sat all winter and winters here are mild mostly 40's, s. nevada. now it starts, i assume it is not starting w/help from the glow plugs only because it is warm know. where do i start and what do i fix to get power to the glow plugs? any input would be greatly appreciated. thanks, linda ann
