Need a Lambda and advice
 

My 1980 SC needs a Lambda. Mine quit.

I'd like to buy a used Lambda that works, but don't know what to budget.

Does anyone have experience acquiring and using a used Lambda?

I can always get mine rebuilt, but I'm interested in the options.

This is not answering your question but how did you confirm the box quit?

Your Porsche number is 931-617-101-00 as you probably know.

You can find one already rebuilt or a used one. Not sure of other options aside from stealing one. :-)

Lorenfb can rebuild it. Search on his user name and he has a link to his website.

is the relay getting 12v from the dome light fuse? is the relay putting out 12V on 87 and 87a?
