Bizarre high beam issue

Hope someone can help with this. My 1981 911sc had sat for 11 years with the last start up about 6 years ago. Without attempting to start it, I took it in to my trusted guy and had the fuel system cleaned, new fuel pump and new master cylinder. Nothing else. Runs great now except for some minor cis issues.

But now my fuel gauge doesn't work, including the low fuel light and my high beams are always on. Pushing the lever forward does nothing. When I pull it back to flash high beams, it goes to low beams. When I turn on either blinker, it goes to low beams!

I'm assuming that when they replaced the master, something got fudded up?

Any ideas? It all worked fine when I parked it.

Thanks for any help

Are the lights actually doing what you describe or is it just the indicator and hi beam lights in the instrument cluster? A dodgy earth on the instrument cluster will cause these symptoms, pull the gauge and check the earth wire.

Thanks for the reply. It's actually on high beams. Blue light and everything. I was thinking that since the master is so close to that stuff, something got unplugged or ??

Try the Wan simple fix for the turn signal stalk - seems to cure all sorts of ills with turn signals, high beams, low beams, no beams, etc. I did it twice, but ultimately had to buy a new stalk.

Take it back to your trusted guy and let him figure it out or do come searching here. Both the things you describe are common issues, fuel sender and high contacts. As luck would have it they can both be very simple fixes you can do in a matter of minutes.

Thanks for this! It looks promising and I will check it out this weekend.
