An amateur guide to troubleshooting the rear defroster on mid 70's 911

[7783911]

I had the thrill (sic) to troubleshoot my Targa (77) rear defroster and switch. Spent a lot of time exchanging posts with forum members and surfing the internet for insights

Hopefully this may help someone who needs to figure out their defroster circuits

If you have suggestions/edits please let me know

Thanks, took some time just to figure out how Print a copy.
I hate working on something and having to rely on an iPad (and reading glasses) for visual references !
