Hi guys--

Looking for places to start troubleshooting

Drove fine 5 days ago
Now weak -- w key in GP warm position
Weak buzzer sound/weak Battery lite/ NO GP Lite at all// NO CRANK at all
When I turn on headbeams--weak lites

Checked Battery (which is 1 years old) and with Car NOT running--
14.2 V-- Which seems like the volts that should be showing with car Running
NOT with car OFF

Any ideas on what to do next? BTW-- Alternator was replaced about 10 months ago.

Thanks!
