Hi Guys,
What an awesome site - I've recently acquired a 2005 PA and surprise surprise it has a couple of issues.
1. The 4WD light isn't coming on when in 4H but the fronts are definately driving.
2. The 4WD light doesn't come on prior to starting (is it supposed to???)
3. I haven't been able to get it to shift into 4L
I started working on 1&2 today - courtesy of this fantastic article http://4wd.blogeasy.com/ that I found linked here.
First up I removed the instrument cluster - hoping for a blown bulb (as you do) - bulb was fine but just for good measure I swapped it for the ANTI-LOCK one just to be sure.
Next I climbed under the old girl - removed the bash plate and started poking - I found that I only had suction on the blue line (when in 4WD). No suction whatsoever from the yellow line when in 2WD (or 4WD but that's meant to be the case isn't it?).
Moved up to the solenoids, got thrown off the scent a little bit by an incorrect assumption (yes yes mother of all $#^ ups) - anyway I thought both solenoids were the same so one should be energised when in 2WD and the other in 4WD. Well no they are both energised in 4WD - but one appears to be normally open while the other is normally closed. At least that's what I found, can anybody confirm that for me?
Freewheel position sensor was measuring short, which I understand sends the signal "I'm in 4wd" which made sense based on only having "blue" suction - but still no 4wd light.
I've ordered new solenoids off ebay tonight ($100 for the pair) hopefully I've diagnosed correctly and not ordered something I didn't need and hopefully I haven't been ripped off does $100 sound reasonable? Once they arrive I'll fit and check the front diff is locking the way it should and reconfirm the position sensor is reliable. If still no light then I guess we move further down the chain to the transfer case and all those switches. Does the PA have all 5 like the Pajero in that article?
So at the end of all that I have a few questions that I hope somebody can answer:
1. Based on the above would it be fair to conclude that my front diff has been permanently engaged since the yellow solenoid gave up the ghost?
2. Would that matter? Does power only go to the front diff when the shift lever is in 4H or 4L anyway?
3. Should the 4wd light come on when you turn the ignition on prior to starting? If the lever is in the 2H position?
4. Should the 4wd light come on when you turn the ignition on prior to starting? If the lever is in the 4H position?
5. Should I be shitting myself yet that I can't get it to go into 4L?
6. Where's the best place to buy the different position sensor switches?
7. Does the PA have 5 switches on the Transfer Case like the Pajero in that really helpful blog?
Oh yeah and because it's kind of poor form to join up and start asking questions here's a pic of last weekends project - a bit of a false floor to make more storage space for the camping trips. Few hours work with a bit of left over mdf and some carpet sourced from bunnings $17 later I reckon it's not to shabby. Its assymetrical because Little generator fits down the left and the fuel on the right, storage boxes underneath, food, clothes etc piled on top.
And here's a photo of the campground that convinced me I needed
a 4wd to replace the BT50 work vehicle that I need to give back at Christmas
Cheers guys

diagram online which I suspect is very similar to the setup in the Challenger.
