Hi there, i'm new to this forum and would really appreciate some help. i have a 2003 Porsche 911. stored for the winter, regularily go start it up etc. over the years never had a problem. this year i let a couple weeks go by and the battery drained low enough not to start but still had some power for doors locks etc.

so i jump started it with my ford explorer. the porsche battery both cables were black and honestly i just didnt see the "+" so i mixed up the polarity. while the ford was running i jumped into the porsche realized smoke was coming from the cables at the porsche. ran to the front disconnected the cables. Cables melted and were garbage. 45 mins later new set of cables show up i realize the mistake and properly jump start the porsche.

It started on the first attemp. i drove it back into the storage unit. Ran the porsche for a half hour. turned it off, then started it and it did all dashed board lights were normal, clock, odometer temperature etc. no abnormal dashlights.

the next day 12 hours later i went back, started the porsche no problem all dash board lights seem fine again nothing abnormal. Ran the car for another half hour. turn off and then restarted it fine. headlights, inside light, gears etc all work "normal" from what i can tell

Now that i've explained just how stupid stupid can be..... can anyone tell me if i screwed my Porsche up? i explained the story to my mechanic / porsche dealer... they said that if anything "blew" it would've have immediately. they think i might have escaped disaster but that i should monitor the alternator. given nothing electronic seems to have been damaged the alternator is the next thing to get damaged.

does the porsche battery and or the car have reverse polarity protection? i've read that some people believe the battery and car do and some dont think so.

Any and all thoughts are welcome please.

Thanks, Bob
