Holden VN Electrical Manual??

anarklov3r · #1 23-08-2008, 05:34 PM

Hey guys, just wondering if anybody out there has a Holden VN/VP/VR/VS electrical manual of some sort...

My problem is that the rear light does not work when the tail gate is opened. All the fuses are OK, brand new globe that works, it just doesnt work.. I cant see a switch of any kind (like on the front doors) that detects if the door is opened or not in order to turn on the light.. So im confused on how this is meant to work.. also turning on the interior lights does not activate it... If i cant figure it out, im so tempted to just join it with my main interior light so they both turn on!

From memory, when the boot opens, something down one of the boot arms rests against a switch, turning on the boot light. Follow the wires around, and see if they lead you anywhere

Get right in there with a torch and have a good geeze ^^

Thats the thing, since is a Wagon, all the wires are in the roof... Which would mean i have to take off the roof trim! I took off a section and had a peek, but wires actually go INTO the roof.. not just under the trim. Id like to leave ripping apart the roof trim until i know where wires go, how far i need to go etc.

Also, there is no switch around the tailgate. thats the thing.. only thing i can think of is that when the tailgate is opened, something inside the door flicks (as the catch is now open on the lock...)

I think that the tailgate switch on wagons is a mercury switch - a silver metal tube about 25mm long by 6mm dia. wired to the earth side of the light.

That the light doesn't work with the main interior light suggests to me that the problem lies elswhere though. I'll have a look at a wiring diagram tonight and post back.

Thanks for that it would be a huge help if you could have a look

What wiring diagram do you have? Theres a few other bits and pieces that i want to have to have a look at, but i havent been able to find a good electrical manual!

I have the electrical diagrams in the book at home - I can grab it and scan the page for you tomorrow.

Looks like this one (V8 engine) but may be No 7 from memory

Try Compupost (I think thats it) on the net - better still try a google search.

Oh cool. I think i may have to get a VN one and a VP one possibably.. seeing as my engine and transmission is from a VP and the rest is a VN Vacationer

I think your right about the mercury switch, I just had a look at my Gregories but it has me confused as it appears the tailgate lamp works independant of the main lamp, yet i know both the lamps light up when I open my tailgate or door.

anarklov3r; So are you saying the main lamp still lights up when the tailgate is opened? Try running a test lamp across the terminals to eliminate a faulty globe.

The main lamp works when doors are opened. The main lamp does not work when tail gate is opened ( i dont expect it to.)

My problem is, that i can not get the rear lamp working at all, be it with the tail gate opened, or the interior light switch enabled. The globe is fine, as i tested it in the main lamp and it lights up wonderfully. Im guessing either the trigger mechanism that detects the tail gate is opened is shot, or the wiring is screwed up somewhere, but i have no idea where it leads and how. Thats why i want a wiring diagram

I put my money on the mercury switch inside the tailgate. remove the trim and have a look

the main lamp is suppossed to work when the tailgate is opened too, so the switch is not triggering at all.

Ive just opened up the tail gate trim and I cant find any switch of any kind? Only thing i found that looked sus was a metal cylinder with another black plastic cylinder inside, connected to a wire, which was cut. But the metal piece did nothing.

Does anybody have an image of what these "mercury switches" look like?
