every time i turn A/C on, my battery light comes on. I have a 91 acord EX
I changed batery connectors
All help is deeply apreciated
I need to pass inspection at the end of the month.

 

It probably means your alternator has a bad diode, which limits idle voltage output. When AC load is added, voltage is inadequate and bat light comes on. Fix is to have your alternator overhauled w/ new diodes, rectifier, and brushes, or purchasea rebuilt unit. I've always done this because some rebuilts are poor quality.

good luck

 

ok, thank you

but its not just while idleing. is this important or will i use the same treatment

 

You can confirm the problem by removing the alternator and having it tested at an auto electrical shop Autozone, et al also have alternator test rigs. I paid about $70 to have my alternator overhauled, rather than buy a rebuilt from AZ or O'R.

good luck

 

thanks
