First round of Glow Plugs was from RA.
Next two have been Motorcraft from the dealer. Luckily they warranted my last batch. Didn’t explain the push button, and played dumb.
I did an open air test on one of my plugs to visualize the glow time. Seems like cherry red is 10-15 seconds. I did a test of my 5 seconds on 10 seconds off, and after 3 rounds of this it was cherry red very quickly. So I’m thinking this cycle was not good after all.
Gonna stick to 10-12 seconds on once then crank it
Will look into Bosch 80034 self-reg plugs. Or find a 7.3 controller to wire in on my trip.
Iam using the 80034 Plugs for the first time this winter.
They heat slower than the Beru Plugs. Iam finding I hit the toggle at least 20 seconds to get her to start.
Depends how cold it is, colder maybe longer.
Do not use the 80034 with the GP Controller.
EDIT:
Some of the colder mornings I have run them to 30 sec.
And then maybe another 10 sec.
At first thought I was having a drain back problem, but just not
letting them heat up enough.
Having used MC ZD-1 plugs for so long, have been skitish about having them on too long, hasn`t seemed to hurt them.
As BlackDawg has said, he hasn`t had one burn out.
They are like a Hot Babe, take`s a bit to warm her up to get going.
