There is no bulletin on this issue. You have a draw in the car. See my notes on dead battery, #4 in the page at the link below.

I have had this before. Once I turn the key to the st position for starting I turn it back a click to the on position and everything works.

Since you changed the battery .. the key needs to re-sync with the system.
According to some web searches the following may work:

• Put the key in the ignition
• Then hold the unlock button down on the key for a minute, while the key in the ignition

Let us know if that works

If some internal light "went out" but the switch is still "on", that might do it.
Something could be shorted. Check power seats' wiring. Radio.

I have this problem too and my new Saab mechanic told me that I would probably need a new instrument cluster. He said a brand new one costs $2500 but that he would order me a used one from a car that had fewer miles than mine as you can set them back but not forward. He both diagnosed and temporarily "fixed" the problem by slamming his hand really hard on the dash over the panel and all the lights and gauges immediately started working fine....for now. I haven't had the work done yet (I have a 1998 Saab 900S with 130K) so if anyone has any other ideas about this I would love to know what they are. This issue with the gauges and dash lights has been happening on and off for over a YEAR and this is the first time someone has had any idea what it is. I already had my ignition switched replaced so we know that's not what it was. THANKS

disconnect (1 post only negative-) battery and put right code in after reconnecting . the two issues are not connected- oh tightenen cables-sounds like they are loose

I hope you put the timing belt in correctly. If you did not, the valves are bent.

Comp systems will run on 10 volts, so I don't think that's the problem. I'd check all cables and connectors pertaining to positive and ground and go from there....accordianman
