Hi All
Triton MN Turbo Diesel MY10 (117,000km)
Currently out bush and after having lots of work done prior to this 3 month long trip,
the cold starting has not been resolved.
It takes about 6 to 7 seconds on cold mornings (4 degrees).
Once it has run for a minute or so it will start immediately as normal.
I won't get to a major town for at least another 3 weeks, and will only have internet access
every 5 days when I travel,so thought I would trouble shoot the cause.
There is no reference in the owners manual as to what relay if any is responsible.
Took off the plastic engine top cover and saw the 4 plugs connecting to the top of the engine.
I assume they were the connections to the glow plugs.
Measuring the first one, I get 7.8 ohm which from previous browsing appears ok.
However, when I measure the voltage during the "Glow Time" it is only 6v.
I thought the plugs were 12v ??
That voltage stays there for as long as I leave the ignition ON,
regardless of the "Glow Time" expiring.
Additionally, although the plug I measured is 7.8 ohm, it is not drawing any current.
Both leads to the Glow Plug are at the same voltage.
As I have extensive electronic experience, this must mean that another device downstream (Relay ?)
is not allowing the current to complete the circuit to negative.
I would have thought all 4 would have a common negative wire, but that is not the case.
There are 8 wires going back into the loom, so there must be more involved then simply
supplying 12v for a short duration.(otherwise I could bypass it manually until I can get it fixed)
I would love to see a circuit diagram, or get some guidance as to which relay (if any)
is responsible.
PS: I have a Scangauge and it shows no error codes, service guys didn't find any either.
Regards
