Expert: Van Date: 1/8/2007 Subject: M-1009 glow plug system
Question Hello again Van; After replacing all glow plugs (13 G NAPA )and glow plug relay (with as suggested Borg Warner S 55 relay) and with a new military glow plug module card (via ebay for $60) I am almost afraid to try and start it up. I have given the idea of a manual push button (to hold down for (what would you reccommend for time ???) and would this have any effect on new module card ???Has the push button way to start affected any other section of the glow plug system ???? I am asking these questions because I really don't need any more problems....and lastly I called the local Army National truck shops (OMS) 2 of them and I asked if they ever had electrical wiring problems with glow plug systems on their M 1008/1009's and they bothsaid no..It was either the relay or module that failed all the time with the accompanying glow plug failure. Thanx again....Ed M.
Answer Hi Ed,
The reason for the S-55, is because it has an isolated winding.
If you measure continuity from one small post to the other, it will show continuity, but if you test from either of the small posts to ground, or the mounting tab of the relay, it WONT show continuity.\
The regular Ford starter relay that looks exactly like it is not that way.
If you measure from each small post to the mounting frame, they will show continuity.
Remember that one of the small posts gets battery voltage when the key is turned to run, and the other is connected to the glow plug module, which completes the ground circuit as glow plugs are needed.
If you use that kind of relay, the one that shows continuity to the mounting tab, then as soon as you turn the key to run, and power is applied, the relay will close....and STAY closed as long as the key is in run.
Yhat might allow one start, but then, the glowplugs will be all burnt out in just a few minutes.
I just found that S-55 had the isolated winding, and have been using them for years.
You might be able to find another.
