You've done good Work and I appreciate it. I appreciate you sharing the Solution with all of us.

There are times that we need someone who will work the finer details of the problem as you have done and this is one of them.

Now OH Members will not be blackmailed by the steam powered Regulator that came with the Car and can use newer and more reliable Technology (aka the 7805).

That was a Marathon effort digging the Gauges out and adjusting them.

I can't thank you enough for your efforts. I admire your persistence in sticking with the problem until you got it done.

Thanks GraemeG too.

Holdenpaedia, they're the brakes Mate.

Yes, good work there! The original regulator just pulses the supply to the gauges between 12V and zero, relying on the slow response of the gauges to average the power supplied, and I have never sat down and worked out what that average is. Although the circuit board on the back of the gauges is marked "5V", I had assumed that it was 8V as everyone talked about 8v, but this is probably only due to the later Commodore gauges using 8V. Now we know that the earlier models are in fact 5V.

Again, good effort and persistence.

Thanks persistence is just a polite word for stubbon isn,t it? I was quoted $200 by a local gauge bloke, with me removing & reinstalling, it,s cost me $9 and a top member here sent me another gauge at a top price, so now i have a back up i,ll try the repair, so far i,ve saved a heap and learnt more about the best cars in the world and hopfully help some more OH lovers.
cheers peter.
