Gordon Sage Posted September 16, 2016 Report Share Posted September 16, 2016 I have a strange problem with my 1999 1.0 Lupo (AER engine, 60k on the clock) - engine will start but indicators/wipers/headlights are dead. They are ok if I just switch ignition on but after starting the engine then they don't work. Seems obvious - ignition switch is faulty. But I have replaced it and the problem remains. In fact it's probably worse - intermittent before and now seems to be permanent. With only the Haynes Polo manual to work from I'm struggling a bit. Where are the relays on the Lupo? Once I get this fixed then I can get back to the rough idling/misfire issue - I'll post that separately in due course........... Quote Link to comment Share on other sites More sharing options...
mk2 Posted September 16, 2016 Report Share Posted September 16, 2016 Try around the battery. It might be a main fuse box or battery terminal link issue.... Loose connection worse when there's engine vibration? Let us know if you solve it. Curious problem. Quote Link to comment Share on other sites More sharing options...
Skezza Posted September 16, 2016 Report Share Posted September 16, 2016 Alternator imo. None of what you've said suggests ignition switch Quote Link to comment Share on other sites More sharing options...

Power to the starter solenoid goes through the IG switch. I wonder if his radio works.... Curious problem. My bet is something with the wiring up near the battery- maybe that link box.

Gordon Sage Posted September 20, 2016 Author Report Share Posted September 20, 2016 Thanks for all the help. In the end I got lucky and discovered the cause just by chance - it was the ignition switch, or more accurately the ignition lock barrel which needed a little lubrication to allow the key to return cleanly to the drive position from the start position - it was sticking between the two.
