I am a newbie and new diesel truck owner (7.3 IDI) and have a question please. My tractors are switch not auto glow plugs. I use them when I think the engine may need them. Never had a problem with them. So why would a conversion like this be bad on my truck?

 

If you forget to turn the switch off, you will burn up the gp's. Better to use a push button if that is how you are going to do it.

 

Yea I'm gonna use a spring loaded toggle. Seams to me glow plugs will last a lot longer.

 

max glow time of 10 seconds at a time. any longer and they can burn up.

 

Thanks for info. I have been counting with the dash light.
