no ignition lights on dash
 

Hi everyone i'm new to this forum and live in the UK, i have a problem with my 1982 911 SC the car is only used occasionally, its was running fine, i came to take it for its mot turned on the ignition and no ignition warning lights the fuel gauge did not register all the things when you turn the ignition on didn't work. The battery is fully charged its on a device that keeps it topped up, the battery earth and terminals are tight and clean,the lights, wipers, horn, windows, all work, the engine will turn over but not fire the indicators do not work it does have a immobiliser fitted but this seems ok i have taken out the ignition switch and checked the wiring i do have 12 volts on pin 15 when the switch is turned on i can use a meter and pretty reasonable with electrics regards continuity and dirty contacts but car wiring takes a bit of understanding can anyone help thanks.

Hi Phill what are you doing on web while the England is playing its heart out in Russia?;-)


Check your connector under the dash.It is possible it is loose..here....

Hi thanks for the quick reply, not interested in footie, i think your pic is for a later ignition switch, mine is like a block that fits to the switch rather than the spade connectors on yours but thanks.

Check fuse 12 (counting back from headlight) with red/black wire for power. (All gauge power)
Maybe just need to spin the fuse to clean up corrosion.
Fuse 11 for CDI power as well.

Disregard the arrows, he's talking about the two round black plugs at the top of the pic.
Also, see that the smaller red wires at the + battery clamp are tight. Seen tons of them loose.

Hi Phil..all 911 from 1974-89 have these 3 plugs under the dash -same..taking you have RHD it is a little different but most likely it is unplugged..also as Dennis said check his suggestions...

No. Don’t know why this keeps being posted? CDI boxes are not fused!

The top of the fuse is powered, I said check for power.
Johhny, you know from building fuse panels that fuse 11 and 12 are bridged.
People troubleshooting need to know if switched power is coming back from the ignition switch and the bridge bar is still good.
In retrospect I should have said ensure there is 12 vdc to the top of fuse 11.

Hi guys checked the 3 plugs, unplugged and pushed back in still no joy cleaned the fuse and holder at 12 also the smaller red wires at the battery terminal are tight. Regards fuse 11 should the power come back here from the ignition switch when the key is switched to on. thanks for the help.

Hi guys thanks for the advice, checked the 3 connectors unplugged and plugged back in, also cleaned fuse and holder at 12, checked the smaller red wires at battery nice and tight,still no joy the fuse at 11 should there be 12 volts returned there when the ignition is switched on. Thanks for the help.
