Hi, can anyone help me please ?
Should there be a light on the guages for the ignition and the battery/alternator ? I do not see any, I just have "fasten seat belt" and "brake". I have the 160mph guages - on a 1973 Firebird.
If it helps, a picture of the interior is at : http://www.angieanddave.com/bird03.jpg
Why the silly/simple qustion ?
I am in the UK - England so it is difficult to get info on other Firebirds easily. (I have a 1973 Firebird Esprit fitted with the rally pack guages as standard - i.e the volt guage and a fuel guage.)
Reason for the question is I have a problem with the alternator. The volts are pulsing and making it idle badly. It always did this but it got worse recently. I tried replacing the regulator in the alternator (S10) , that worked great for 50 miles and then the issue came back. Maybe I replace diodes next + regulator, maybe the whole alternator. In the UK you just do not have the places like in the US where you take and alternator for a health check - so I have to work it out for myself. Trouble is the wiring loom is a bit butchered and I am wondering if I am incorrectly wired and missing diodes or resistors or other bits and bobs. So until I have the wiring fully worked out I dont want to keep throwing bits and money at it. It looks OK so far, but I am trying to trace the ignition line to the alternator.
Cheers for any help – Dave
