My 1983 BJ60 Glow Plug timer has broken .I hooked up a manual switch (Wilson) and have Changed to the 10.5 volt glow plugs. Will this work or do I need to bypass the resistor going to the buzz bar. I have read all the threads on glow plugs and not sure if I should leave the resistor in place. I would guess I should bypass the resistor but not sure. As I understand with the resistor in place the voltage will be less than 12 volts. I would guess as I am writing this that if I am not getting 12 volts to the glow plugs they will not get hot enough and I could check this with a volt meter... Origionally I was using the Super glow system with the lower 6 volt plug ... Thanks
 
i'm running a push button and relay set-up as the plugs are high wattage/amperage and dont have the reistor in series with the plugs.(power to glow plugs runs from battery to relay to buss bar attached to plugs.

Actually im in nz so not running this at the present time but was before i went down under(no pun intended)
 
Hey, if you are pulling the engine mounted "Super Glow" stuff can you hang onto it and send it to me?
 
The resistor is usually for the secondary glow cycle (after the light goes off). You don't need the resistor with a direct switch, in fact, it may cause issues.
 
I left the resistor in place. it works. No need to pull it. Just glow it longer. IMOP leaving it in just uses more juice. But the end result is the same...

The original poster indicated that he is now running 10.5 plugs. The resistor is intended for the lower voltage plugs that would have been in there with the super glow system.

Yup I know. I also have the 10.5 plugs and the resistor in place. Still works fine.

Ideally you could put a meter on the busbar with the plugs on and see the voltage, then bypass the resistor and try it again.. There will be a voltage difference. How much I dunno. But the plugs still get hot enough for a good start with the resistor in place. But more amps is used I am sure...
 
After 4 starts with the glow time of 20 secs or less all four NGK Y107R 10.5 volt glow plugs burnt out. No continuity at all. These are being replaced under warranty. I found a phone number for NGK and talked to a tech rep. He said these Plugs are a fast glow type and get to their temperature in 6 secs. But could not explain how all four could burn out so quickly, even with a 20 second glow of 12 volts. I haven't tried the new ones yet but I imagine at 6 sec on a -10 morning there will be lots of pounding and smoke...
 
I installed the Ngk 107R plug thinking the were high voltage because 10.5 V is stamped on them and glowed them like they were NGK 147T, which must have burnt them out. I cross referenced this with Delphi Glow Plug Catalog and it seems to varifiy this. So I think this should work now and thanks for all the replies...I would have been lost without this site...
