Thank you. I will get it checked but was wondering if there is a fuse for alternator i have not checked. I have looked at all fuses but under steering wheel which are more difficult to get into, or a loose wire? Would connecting battery pos/neg wrong way in jumpstart by mistake, have damaged alternator?

Usually reversing the polarity would not damage the alternator as the fuses would have blown before any damage occurs but for electrical components, it can still occur.

You needed a jumpstart, that could mean the alternator was already bad before the problem. Was the charge indicator light showing prior to this occurring?
If the problem is due to a fuse, you would not see the charge indicator light when ignition switch is turned on.

Alternator fuses are underhood.
