172 battery and stop light

[ronnyp]

Should the stop and battery light be on if the alternator is not charging?

I've been to look at a 172 with the stop and battery light up on the dash. Its not charging and looks like its had a new alternator fitted that failed after two days. Should the stop light be illuminated if its not charging or could this point to another fault?

I'm presuming that its just a duff altermator but don't want to buy the car if its git more faults.

Any advice would be great.

Thanks

More than likely as this has been covered a few times.

Change the alternator and Aux Belt kit and just for good measures i would suggest the battery also.

The only two alternators i would buy would OE valeo or lucas.
