Have I damaged electrical system during jump start
Hi everyone I'm hoping I can get some advice. I let the battery on my V6 GTV go flat as I hadn't run the car for a few weeks after I moved house.
Not a problem I thought as i have jump leads on case of breakdown on a recent trip to the Scottish Highlands. However I think I may have screwed up getting her started. Once I had her going and the donor car was also running I decided to remove the jump leads and leave the GTV running under her own steam. But I removed the black earth lead first leaving the red positive lead attached.
Since I've done this I've had two issues I'm sure are as a result. First the car has am amp kit connectes to 2 rear speakers, which I heard make a popping noise and now only one speaker works and seems to be producing lower power output. Secondly the aircon is not producing cold air anymore and is making a strange hissing sound when turned on.*
Could I have damaged the car's electrical system by leaving only the positive lead attached with no earth to result in these issues, or are they unrelated?*
Thanks for any help in advance*
