hey guys

my tacho seems to be dead...sumtimes it flickers, but most of the time it just drops down past 9000rpm (at the end of the gauge) and doesnt move, then sometimes it might start boucing around the 6 - 7k area wen ur really doing around 1500rpm....

what could it be?

has this happened to anyone before, whats the solution?

thanks :(

Pointer detached from pointer shaft easyiest fixed, nackered tacho pickup maybe, bad earth maybe (but if nothing else is playing up this is unlikely), obscure electronic fault fixed by Nissan by replacing complete unit. :unhappy:

Hope you get it sorted economically,

Cheers GW

where is the tacho pickup? could it be a loose connection or anything

yeh everything else works fine....

thanks

Loose connection is as you say also a possibility but if this is the case why don't all tacho pointers hang low when ignition off/no power? I would ask myself how can the pointer perform this trick & to me at least the answer is "it has somehow become mechanically disconnected from pointer spindle" to be able to float around &/or dangle at random in the manner you have described. I do not know where your tacho pickup might be placed, I have not had to dig into this to date, if I did need to I would be wading through the Japanese service manual floating around the forum environs (google) but I am sure others have this knowledge at their fingertips.

Time to visit a Skyline/Jap import friendly autospark in your neck of the woods I think.

Sorry can't be more helpful.

Good luck GW :)

Hope this is on topic but my speedo is out by aproximatly 1/2 so when i doing 30kmph it says i doing 15kmph. any suggestions?

Best option ; Re-scale dial 0 - 360kph? :)

Seriously, has this problem existed ever since your conversion to 25DET? Or has it popped up out of the blue? There are range jumpers on the cct board for the speedo/tacho array, discussed in depth on this forum in the "White dial 320kph group buy thread". Check it out & see what you come up with.

My 2c

GW :)

    • Seems like a decent result for a modded JZX110. They are bulky in comparison to the 100 and 90 models (which I'd prefer myself) but they are getting very few and far between here in JP these days. Thanks for the detailed review and the import process into the UK. I also have a car which I'm hoping to export from Japan at some stage so it's good to know if someone from the UK was interested in it. By the way the corrosion underneath is par for the course for cars which were located in/near the mountains or along the Japan sea coastline. They get huge amounts of snow every winter and the sodium chloride is used on the roads. Many cars have some kind of rubber like treatment underneath but they tend to limit it to the wheel arches underbody and fuel tank. Suspension arms and sub-frames will have similar corrosion to your JZX110 which is a common sight. See it all the time and car dealers here generally don't even mention it unless asked.
    • If the sound goes away when you clutch in, the 1.5/2 way diffs are just shit, and you are a normal person. The diff is likely "fine" but driving at anything under 30kmh is a violent horrible experience. It would be exaggerated with solid diff bushings and subframe bushings if you have those.
