Q: Replaced battery, hooked up battery ass backwards. Hooked up correctly and now alternator smokes and gets hot ?

asked by on

Installed new battery, hooked it up ass backwards. Have hooked it up correctly and now alternator smokes and gets hot?

My car has 100000 miles.
My car has a manual transmission.

Reverse polarity, at the battery, in a car’s 12 volt electrical system can cause a variety of effects including damaging the alternator, diodes and the numerous microprocessors on a vehicle such as those in the powertrain control module (PCM). If you have successfully started and run the car, and all accessories work, that’s a good sign and you are lucky. However, the smoke and high heat from the alternator are sure signs that the alternator was damaged by the reverse polarity. To avoid future problems, you can replace the alternator. To request replacement, please use YourMechanic’s alternator replacement service page and the responding certified mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
