Well the PNV seems to have developed a few problems in recent times. Why is it that things seem to go wrong when you are trying to sell?

Anyway here they are:

1. Clutch is not holding pressure. I can pump it up and it will work while I drive. Let it sit for a day or so and the pressure is gone again and have to pump it up. It doesn't seem to be losing any fluid and can't see any visible leaks, so not sure what is going on.

2. One of the headlights has gone dim. I have been running 90/100's on the low/high. First the left side one went dim. Next time I turned the lights on it blew both fuses, replaced them, blew them again. Replaced globes with the ordinary spec(55/60s?) and fuses and it seemed to be alright for a while. Now the right hand side one is dim all the time. Its dim on both low and high beam. New fuses make no difference. Points to a possible earth problem, loose or burnt connection?

Any ideas guys?

sound like the clutch master cylinder is poked. New seals or a complete new one is required.

The other one sounds like yourve cooked your wiring. 100/90 are nearly double the current draw over a 55/60 close to 15amp's compared to the nomanal 10amp. Id say check all your wiring, follow it back im sure there will be a melted patch. If you wish to run higher wattge bulbs best to install a secondary loom kit and relays and feed them directly off the battery, Work well for me. 100w/130's and 100w high beams work well :)

I'll go with stagefumer as far as your clutch goes, I had the same problem when mine sat for 3 years in the garage.

It wasn't such a biggie for me as I was replacing the slave cylinder in any case.

For anyone that wants to know and is using a heavier weight clutch plate diaphram the VL uses a 7/8 (22mm) slave cylinder as opposed to our 3/4 (19.05mm) More fluid, less pedal pressure and easier on the legs.

I have an auxilliary harness for mine, it's got written on it "Bosch System Harness" and as per pic, it has it's own relays for each bulb and heavier gauge wiring. I'm going to use it with Rallyart 170/130 H4's and IPF 130 H1's.

What happens when using high power globes, the heat generated by the power draw from the globes, is too much for the standard wiring, as it's not designed for them. Maybe if you source low input high output globes, like designed for the new style polycarbonate headlamps used in some cars today they will fix your problem. But if the heat generated has already burnt the wiring, take it to an auto elec and get him to rewire heavier gauge wiring across the headlights and your problem should be gone.

Hi all , when I had the DR30 I spent a few afternoons at Pick n Payless cutting into headlight looms on MR30's . It was very obvious that the Australian delivered cars had heavier gauge wiring than that DR30 did . I'm not sure what a PNE would have but its worth a look to find out .

Nissan went to a lot of trouble to make the high low system work off two relays and operate the gauge lights as well . Mine carried the full current across the stalk switch as well which is not flash . At the time I think I worked out that it really needed 6 relays switched by the std loom to make it all work (dash as well) ie one for switched earth on each side and one each for high and low beams on both sides . Standard they are quite involved .

I would also take a close look at the reflectors in each light because the age of the things makes them a bit suspect . The Iron Mask lights have a bad habbit of damaging the chrome plating near the bulb making low beam a bit dull . There are supposed to be mobs around that can replate them but for the non Iron Mask lights good seconds are probably still around . High wattage bulbs put out a lot more heat so be sure the light unit can cope with this .

Cheers A .

Thanks for the ideas guys will have a look into it all.

Is there any easy way to tell if the clutch master just needs new seals or a whole new one?

I know running the bigger globes wasn't a great idea, but it was a good easy fix that lasted a far while really. Am now going to have some fun taking of the stuff that all the wiring is in to find where the problem is.

At a guess it wont be your master cylinder I would say its your slave cylinder as ive seen heaps of them stuffed on R30s before, but I may be wrong! Last time I brought a slave cylinder it cost around $25 and I got a master cylinder priced up at the same time and they wanted $45 thats NZ prices remeber though!

    • Place the new daughterboard in the case and mount it using the 3 small black rivets provided, and reconnect the 3 factory ribbon cables to the new board Then, use the 3 piggyback cables from the daughterboard into the factory board on top (there are stand offs in the case to keep them apart. and remember to reconnect the antenna and rear cover fan wires. 1 screw to hold the motherboard in place. Before closing the case, make a hole in the sticker covering a hole in the case and run the cable for the android unit into the plug there. The video forgot this step, so did I, so will you probably. Then redo the 4 screws on back, 2 each top and bottom, 3 each side and put the 2 brackets back on.....all ready to go and not that tricky really.      
    • Onto the android unit. You need to remove the top screen because there is a daughterboard to put inside the case. Each side vent pops out from clips; start at the bottom and carefully remove upwards (use a trim remover tool to avoid breaking anything). Then the lower screen and controls come out, 4 screws, a couple of clips (including 3 flimsy ones at the top) and 3 plugs on the rear. Then the upper screen, 4 screws and a bunch of plugs and she is out. From there, remove the mounting brackets (2 screws each), 4 screws on the rear, 2 screws top and bottom and 3 screws holding in the small plates on each side. When you remove the back cover (tight fit), watch out for the power cable for the fan, I removed it so I could put the back aside. The mainboard is held in by 1 screw in the middle, 1 aerial at the top and 3 ribbon cables. If you've ever done any laptop stuff the ribbon cables are OK to work with, just pop up the retainer and they slide out. If you are not familiar just grab a 12 year old from an iphone factory, they will know how it works The case should now look like this:
    • Switching the console was tricky. First there were 6 screws to remove, and also the little adapter loom and its screws had to come out. Also don't forget to remove the 2 screws holding the central locking receiver. Then there are 4 clips on either side....these were very tight in this case and needed careful persuading with a long flat screw driver....some force required but not enough to break them...this was probably the fiddliest part of the whole job. In my case I needed both the wiring loom and the central locking receiver module to swap across to the new one. That was it for the console, so "assembly is the reverse of disassembly"
    • But first....while I was there, I also swapped across the centre console box for the other style where the AV inputs don't intrude into the (very limited !) space.  Part# was 96926-4GA0A, 284H3-4GA0B, 284H3-4GA0A. (I've already swapped the top 12v socket for a USB bulkhead in this pic, it fit the hole without modification:) Comparison of the 2: Basically to do the console you need to remove the DS and PS side console trim (they slide up and back, held in by clips only) Then remove the back half of the console top trim with the cupholders, pops up, all clips again but be careful at the front as it is pretty flimsy. Then slide the shifter boot down, remove the spring clip, loose it forever somewhere in the car the pull the shift knob off. Remove the tiny plastic piece on DS near "P" and use something thin and long (most screwdrivers won't fit) to push down the interlock and put the shifter down in D for space. There is one screw at the front, then the shifter surround and ashtray lift up. There are 3 or 4 plugs underneath and it is off. Next is the rear cover of the centre console; you need to open the console lid, pop off the trim covering the lid hinge and undo the 2rd screw from the driver's side (the rest all need to come out later so you can do them all now and remove the lid) Then the rear cover unclips (6 clips), start at the top with a trim tool pulling backwards. Once it is off there are 2 screws facing rearwards to remove (need a short phillips for these) and you are done with the rear of the console. There are 4 plugs at the A/V box to unclip Then there are 2 screws at the front of the console, and 2 clips (pull up and back) and the console will come out.
    • So, a bit of a side trip, but one that might be interesting for people with JDM cars and japanese head units. I know @Pac previously posted about a carplay/android auto adapter he installed which used the AUX input, and @V35_Paul put in one of the Tesla style units that replace both screens. The option I went with was a Lsait LLT-YF-VER5.87_2 (https://www.alibaba.com/product-detail/Lsailt-8GB-Android-Multimedia-Interface-for_1601187633672.html). Price was $1,150 for a single unit although they are much cheaper if you are willing to buy 2....$857ea. Make you you get the version 2 not version 1, it is faster and has a better UI - this is the manufacturer listing: http://www.lsailt.com/product/348.html. BTW if you've never bought from Alibaba before, don't be concerned....these guys can't stay in business unless they are responsive, ship fast etc, they were excellent (probably faster shipping than most local places) So, this was my task for a lazy Sat afternoon....looks complex but was all done in a few hours (it probably helps that I had some of it apart before so it was a bit familiar). I also decided to add a HD USB drive recorded at the same time and the unit also supports an aftermarket reverse cam (if you don't want to retain factory) and also AV in and HDMI out It looks much worse than it is, in fact in was genuinely all plug and play (no custom wiring at all). This video was pretty good (skipped a few steps), unfortunately they are an Aussie seller but no longer sell this unit (I guess Carplay/AA adapters are easier to install and much cheaper) https://www.youtube.com/watch?v=T5hJfYOB8Dg
