no wts glow plug light

I have a 1994 f250 7.3 idi with just 69,000 miles.When I reach back from a fishing trip the truck would not start. The glow plug wts light would not come on.Was able to start the truck with starting fluid.I checked the voltage on the glow plug controller relay at it is !2.37 on the Positive and with the key turned on it is 11.72 on the other terminal.Any ideas what to check next?

watch your dome light when it dim's the glow's are working, if the WTS light blinks only, than controller may be bad. if the dome light dims for only a couple seconds the controller is bad. # GPR8 At O'Reilly's $97 ready to install with relay. you can check your glows with a test light, hook test light clip to positive batt post and then one at a time remove wire from glow plug and touch test light to glow plug. if the light comes on glow is good.
