Hello and thank you for using Just Answer

I'm Paul and I will help you with your Question

 

have you verified voltage to the alternator?

 

it is not uncommon for aftermarket alternators to be defective or for the wrong application

 

if you have power coming to the alternator change it for a different brand

 

let me know how you make out and if you need more help

car starts and runs fine it is now the batt light and brake light will not go out
Expert:  Paul M ASE Master replied 5 years ago.

the alternator will cause these lights to come on.

 

if the lights were not on before you changed the alternator you need to change it for a different alternator it is either defective or not compatible with your vehicle (wrong application)

the lights were on before and the alt was not charging batt now alt is charging but lights still on
Expert:  Paul M ASE Master replied 5 years ago.

the Battery and Brake lights come on when charging voltage is low

 

do you have a voltmeter?

 

what is it charging at?

 

did you check the 100 amp fuse that feeds power to the alternator?

 

start the engine and put your meter across the battery what is the voltage..

 

with the engine off and key on do you have battery voltage to the RED and the PINK wires at the back of the alternator?

 

these lights come on if charging voltage is low or the alternator is defective.

 

let me know what you get for battery voltage engine running and what you have for voltage on the RED and PINK wires. if the RED and PINK wires both have power with key on the alternator is defective.
