Sorry can't help with the resistor other than to suggest replacing it with a known good one, but I expect you have already thought of that.
What is the purpose of the dropping resistor in this situation? Is it to do with the glow plug timer or???? Do you have info re the expected in & out voltages so you can check them?
EDIT: This thread on another forum may help? https://www.patrol4x4.com/threads/la...nifold.199506/

Genuine Nissan Glow Resistor
Suit GU & GQ Patrol's Fitted with this Resistor from Factory.
This Resistor is fitted into the intake manifold of Some TD42 Models
Some cars don't have one at all, some have it but it doesnt plug into anything, and some have it and Use it.
The purpose of the Unit, is to allow the engine to continue to cycle the Glow plugs in very cold conditions.
These are Mainly used in Overseas model Cars, However if the car is fitted with it, and it is not working properly
Then it can up-set the glow system and cause it not to work Properly.
Seems that bypassing it is a reasonable strategy in our warmer climate.

I am he, fear me
Wot Cuppa said and quoted ^^^^
In the hotter climates like Aus (using standard glow plugs) you should be able to turf that resistor and eliminate any problems it is causing without any adverse effects.
Dolphins are so smart that within a few weeks of captivity, they can train people to stand on the very edge of the pool and throw them fish.

Did you check your glow plug voltage when it is cranking? You may have crappy contacts on your glow plug relay which is causing a voltage drop under load.

Sorry for late reply Billsgu, auto electricians checked and tested everything that could be checked and tested electrically regarding the glow circuit including relays, timer and glow plugs individually, as well as when engine is turned off with the ignition on, when cranking and when engine is running. We even went as far as getting a mates ute that has the same glow circuit setup ie with the dropping resistor in the inlet manifold and it tested almost identically on all the above mentioned tests, differing by .1 of a volt in one instance. Again i have absolutely no answer as to how or why undoing the dropping resistor connector plug and looping the two terminals on the female part of that connecting plug fixes the symptoms of very rough idle and clouds of white/grey smoke on cold start ups but it 100% definitely does and not knowing how or why it does frustrates the hell out of me, but i have used a small length of heavy gauge wire put a terminal on each end and looped the connector plug as i described and it starts beautifully. A complete mystery to me! I spoke with a farmer from the area around where i live who told me that he had a 2003 gu td42t ute that had the same issue not long after being bought new ( it wasnt even 2 years old ) and despite 4 or 5 trips to the nissan dealership from where it was purchased as well as being taken to other mechanics, auto electricians and diesel fuel injection specialists, he could not get the issue resolved and in the end out of frustration sold it for less than it was actually worth at the time because in his words, "it annoyed the s..t out of me and i couldnt put up with it every morning". There has to be an explanation as to what causes this and how it can be fixed without resorting to looping electrical circuits that for some reason solves the cold start issues mentioned above. Any suggestions or known fixes for this would be hugely appreciated if passed on.

Hi Badger. If your playing with the glow plug circuit and getting positive results what do you think the problem might be?
Get hold of a DC current clamp, put it on the main wire feeding the glow plugs. If your mate is turning the ignition engine cold and you are seeing less than 20 amps on the meter keep looking at glow plug shyt.
