Ive had a bad diode draining the battery , also a bad connection on the alternator , a bad battery connection , bad radio , bad ground , bad ignition switch , bad alarm , bad immobiliser , bad door switch etc etc etc .
You could well be correct , you could well be wrong .
You could scope it to test , or you could meter it .
I too had the EXACT thing happening within the last 3 months on my boxster ....
It was the ignition switch ...
I'm used to diagnosing before ordering parts and scheduling labour ....
It's what I do for a living , and have a huge amount of test gear at my disposal ( each Instrument tech working for me carries about 20Ks worth in their toolkit)
If I did it by guesswork and throwing money at it , no matter what past experience tells me , I'd be claiming unemployment
This is me diagnosing using experience .
Just a pity the guy had allready been to the main dealer , then 2 specialist that diagnosed with his wallet first ....
