The air conditioner keeps running down the battery?

Hi,

If the A/C is causing the battery to discharge, we may have a weak alternator that can't keep up with the load. Is that what you mean or is it something different? For example, the A/C indicator light stays on when the key is off.

Let me know. Also, I need you to check the alternator output. It is really easy to do and only requires a basic multimeter or voltmeter.

Here is a link that explains how it's done:

Let me know what you find. Note: When testing, turn the A/C on to see what the battery voltage reads.

Take care,

Joe
