WTS light won't shut off

[dstang97]

I searched and all I could find was to switch to a push button for glow plugs. The only problem is I already have. The timer seems right about 10 sec in 30 degree weather. It turns on then after 10 sec shuts off then comes on a minute later and stays on. ??????

check the connector for the temp sensor.

check the ground wire for the timer.

Remove card, throw in garbage. Be your own timer.

hobie237 is right, if your truck is over 120 000 miles. Electronics are of poor reliability. But pay attention, these plugs are SIX SECOND PLUGS, the buzzer is set to 6 to 7 seconds for in the electronic card there are some registors which limit the power to the glow plugs by a very little to make them surviwe.

so pretty much if it continues just remove the bulb. The only reason I like it is when you shut it off and restart later.

If you remove the bulb there really isn't much point of keeping the card in there if you're on manual plugs anyway.
