Electrical problem.. 14.4 is normal, mine runs at 13.x to 10.4....

Alright, my radar detector told me my alternator was bad, so I had it tested, and sure enough it was..

So, I had that replaced..

But, I am still having the problems....

Car was perfectly fine, but I let it sit for 3 weeks while I was in Germany...

Drove fine for the first week, then the power started dropping, which is when I had the alternator and all tested..

So, this morning, I got up to go to school, and my car stalled at the second stop sign that I had to stop at... (power was at or lower than 10.4)

Under normal driving circumstances it would be at 14.4, but while driving it hovers anywhere from 14.1 to 10.4 where my radar detector gives a low voltage warning...

Starter, Alternator, battery, all cables and grounds were tested and checked out fine...

I am using a Beltronics RX65 hardwired to my car..

Any idea what this could be?

The first thing to do would be to check the voltage at the post on the back of the alternator and then check it at the battery terminal. If there is any more than a .2 volt drop then you have high resistance in the charge wire coming off of the alternator. You also need to check the wire coming from the ignition to the alternator plug for 12 volts with the ignition on and the engine not running. If all that checks out ok then you have somethign shorted that is causing a huge draw on the alt or the new alternator isnt working properly. Sounds to me like a wiring issue somewhere.
