Good point. I was wondering about that too. I felt each one to see if there was any residual heat but it was so dang cold and my hands were numb so it was hard to tell. I'm assuming there would at least be a little bit of heat on the outside of them?Sorry it didn't fire. Did you verify that the glow plugs were working properly?
Yeah, I saw that. Unfortunately I did not bring an ammeter. The lights did light up though on the dash so I'll make sure I have the proper tools for the job next time. Also, it will be in spring so it should be 60* instead of sub 20*.Chroniekon listed the procedure for testing the glow plugs on page 2 of this thread.
