i have used champion and autolite the time seems to be around 15 to 20 secs maybe a bit longer when i turn them on the controler seems towork fine but i dont know if it is working right or not
i am not really sure for the wait time as for each time i start it costs me one or two glow plugs

Put some good glow plugs in there then bypass that controller with a manual push switch. Then there's no question if they're coming on and for how long.

ok but is there a way i can check the controler to b sure its working properly and not overheating the plugs for too long is there a sensor that tells the controler the engin is cold and is causing the timer to stay on too long

i belive that 20 seconds is to long...the newer controler see's the ohms of resistance in the gp's to control after glow during warm up..the wait to start lite will blink two or three time's when cold out..check all conections even if they look good, don't forget the grounds..controller may be bad...
i ain't rite

glow plug heat time is controlled by resistance and temperature.
if it is 50 degrees out, the glow plugs on my 88 will only wait to start around 10 seconds. if it is 10 below, they wait to start 20-25 seconds.
i have seen autolite and champion glow plugs burn out after one 10 second cycle. you can get the proper motorcraft ZD-9 glow plugs from rock auto for $9.69 each.
