My check gauge light comes on everytime I stop what could the problem be?

Hello,

The check gauges light can come on due to low alternator output.
It is possible that at idle with low engine speed the alternator is unable to sufficiently change the battery. Which can lead to the check gauges warning.

A good first step would be to test the alternator output to the battery with the engine running.

Here is a helpful video that show exactly how to do that:

If the output is low, then it could be a bad alternator that needs to be replaced.

I have attached the alternator replacement procedure below for your reference.

Please let me know if you have any questions.
Thank you.
