doesnt explain why the aircon fan worked ?

think thats what you said earlier
Have you had a chance to call Davies Craig yet
We have spoken and they are coming to the party, great customer service but everyone just wants to know why.Quote:

Which explains why they worked fine at lower speeds up to 80kph they would be fine I think
If excess load was put on them to the point they have stripped then the current produced would cause some kind of ill effect either blowing a fuse or worse.
It would be interesting to see if the still stripped if they werent even connected and couldnt run at all.
What sort of conditions were present when this has happened?
Agree, there is no way you can load the fan enough to strip it if it is installed correctly and/or isn't a defective batch
It can't be no load issues either as the motors will spin them faster than they can freewheel.
There are gazillions of these things out there on vehicles that tow vans etc and go a sight faster than a 'Trol and no problems.
A truly curious problem...
That would be a good test indeed.Quote:

Yeah but things like coolant temp, exhaust temp, oil pressure, trans temp if auto etc etc
Only nissan gauges unfortunately mate and manual.Quote:

Ok. Im not sure what coolant temp sensor they use with the 6.5 but the nissan gauges sometimes dont actually start to move until around 100degrees.
No oil pressure gauge...lolQuote:

Just for reference (sort of), my 6.5TD is on about 109 degrees when the Nissan gauge reads around 3/4 and yes, the Nissan gauge doesn't move until about 103 degrees or thereabouts. At 115 degrees the Nissan gauge is nearing the overheating mark. Those temp readings are from the thermocouple on the thermostat housing.
Also, my A/C generally adds up to 5 degrees celsius to my temps.
An interesting problem.
I'll hopefully shed some light on this soon gents.
Must say that the customer service from them is outstanding!
Hey Andy, did you ever work anything out with this?
I was waiting for someone to bump this..lolQuote:

They will get back to us soon with their finds.
We are all stumped to be honest.
I will come back when I know.
I'm thinking a bad compound or an accidental mispack of 24 volt motors in 12v package but I'm only speculating of course.
What I can say is they took the problem serious and will find out what happened. I'm almost hoping it was our side but I just can't see it.
Really happy with their service though mate. Don't really see that kind of service much these days so kudos regardless of the crap mark went through.
The difference it made to marks patrol was quite impressive too.
If these ones check out I could be very tempted to wang these in mine when money permits.
They would compliment the sprinkler system quite well =]
that's funny...lolQuote:

But didnt the same thing happen after fletch replaced them? If so i wouldnt think it's the fans.Quote:

All this intellectual humour has got me in a spin.
Will certainly be interesting to read what caused this problem.
Too much of a coincidence for all three fans to have same problem?
Surely the amount of checking has them installed correctly?
All indications point to incorrect installation/fan rotation, but the third installation was by a separate mechanic, both shops couldn't get it wrong?
Where was the power supply picked up from? Could it be an over voltage/amperage situation?
Just thinking out loud fellas, go easy.
Alternator giving too much power,,,, then not enough,,,, if the brushes are only touching on the edges of the comutatorQuote:

What alternators do you normally us with a 6.5,
Interesting problem though
It was all tested though, no issue with power supply.Quote:

No probs mate, it's all done 100%
100% regulator producing correct power :)Quote:

After all its a mix and match 4x4, Im doing some shops early next week I'll ask if any have heard of this happening before.
Dying to know what it is, 5 cents or $500 fix
If they are fused (which they should be) then these would be blowing left right and centre with the amount of amps required to melt these things. Even your standard relay would most likely be cactus due to the current draw.
yep both are fused and never blew nor any signs of excessive heat/melting.Quote:
