Q: Car will not start after replacing battery and alternator

asked by on

Just replaced battery and alternator. When alternator was replaced the support bracket was not put back on... the next day I turned the car off and it wouldn't start. It started but onlu stayed on a few seconds and died.. after the third time it wouldn't even turn over.. does the missing support bracket have anything to do with it?

My car has 117000 miles.
My car has an automatic transmission.

The support bracket is a structural element and therefore must be installed to maintain proper alignment of the alternator. However, as far as its temporary omission being a possible cause of the no start, it has nothing to do with the problem. If you started with a fully charged, new battery and you are now presently at the point where the battery is so discharged that the vehicle starter motor won’t function, that could signify a failure in the charging circuit. I would recommend that you request a charging system diagnostic and the responding mechanic will get this resolved for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic.
