On the way down the motorway this morning the speedo needle on my 1991 j-spec 300zxtt started to bounce from the 65/70mph I was going down to 0 and back up again. It seemed to stop after a while but when I came off the motorway to a left turn the speedo needle droppde to 0 and stayed there and the steering got VERY heavy. I am thinking that this is a problem with the wiring to the "de-limiter" or the de-limiter has failed. Anyone got any knowledge on this matter?

 

As an aside, WOW is the car heavy to turn without power steering!!!

Thats your speedo converter.

 

My did the same thing, and its down to cheap and crappy converters.

 

I can get you a good one if your interested, and there easy to fit.

Damn, I paid Protech £80 for it. Is it the unit or could it be a wiring problem?

Umm, I think that could be more a problem with the speed sensor or something suchlike, other members will be able to provide more info, but dodgy speedo and heavy steering has in the past been said to be speed sensor, so dont change the de-liniter thing yet!

 

Also, with power steering switched ff the steering will become abnormally heavy, as you are using hydraulics without assistance, should it have non power assisted steering at all, it would be heavy, but not as heavy as switched off power steering

the steering becomes heavy because it is speed sensitive (light when slow, heavy when fast).

 

the speed sensor signal goes through the speed convertor, so could be either component at fault.

 

cheap speed sensors seems to be a common problem, and speed sensor problem is not that uncommon either.

Consult showed faulty speed sensor, part = £74-50 + VAT & fitting. No cheap months with this car and April had been a good month till then.
