The car was shaking like a mother at 70km/h upwards.
I thought what could be wrong as the wheel balancing and alignment was done and whole suspension and parts are brand new including the steering rack.
I jacked the car up and ran it in 2nd gear, low and behold the LH short drive shaft is shaking like a pole dancer in the strip club.
I remembered that the shafts that was original to the car was sold with some brakes last year sometime, I just grabbed two shafts off the shelf and used them, mistakenly.
I removed the LH shaft and found a tested straight replacement and then only it worked after building the new cv etc over.
I have been putting some kms on the car and it gets very irritating driving the car and guessing the rpms as I am trying to keep the engine under 3000 - 3500 rpm due to running it in still. I have tried in vain to get the original rev counter to work and I just cannot justify having the cluster serviced and rebuilt to the tune of some R4500.
I have been looking at aftermarket rev counters for some time now and toyed with the idea to fit a digital one on the steering cowl, but eventually thought that fitting the rev counter in the space of the original will have to work.
So after some measurements and looking at some local offerings I decided the 3 3/4 inch Autogear tachometer cheapy will have to suffice.
I started by removing the rev counter out of another cluster that I have and used it as my test mule. Spent a good 2 hours measuring and test fitting and looking at how exactly to fit the new rev counter.
Eventually the cuts was made and the screws tightened and ....
I could not fit the face cover due to the length of the rev counter to the back behind the face been so long.
Next came the wiring, with all the test fitting I managed to tear first the white and then the green wires off the back of the rev counter, so that was fixed.
The cheap chinese wiring diagram only shows the green wire going to the coil, it does not specify to which pole on the coil. I remembered that I sold a electronic ignition kit to a client and he managed to blow it when he fitted a after market tacho. So I went and did some research on the net, turns out a lot of after market tachos are fitted to a lot of cars with many different wiring setups. Eventually I found a video that expressly warns to only attach the green wire to the negative side of the coil.
Out with the cluster, the rev counter was removed.
Then for the first time in probably 10-12 years of owning this GTS it has a working rev counter, although the white face will need some getting used to the LED back lights are very bright now next to the incandecent std items of the other two gauges, but what the hell...
Own some minis, break them, fix them, improve them, test them to the limit....
