Hi Pearl, I have a 2005 ponntiac montana SV6
3.5L with 125A alternator. Shortly after startup the battery light comes on. Between startup and light on it is charging. 14..4v. When the light comes on charging voltage drops to 12.2. Any ideas? Thanks Randy
JA: Lots of things can cause problems with the battery. The Pontiac Mechanic will know what to do. Are you hoping to fix this yourself?
Customer: Yes. I am a retired ASE.mechanic a little out of touch with today's technology soooo....would like too fix it myself
JA: Great! What have you tried so far?
Customer: Battery load test, alternator output test, connector "wiggle" test, checked all fuses/relays, checked all ground connections,. It acts like a relay kicks out when the light comes on
JA: Is there anything else the Pontiac Mechanic should be aware of about your Pontiac?
Customer: No other recent repairs or electrical work. Its my wife's vehicle and she reports no unusual events when it happened the first time
JA: I'm sending you to a secure page on JustAnswer so you can place the $5 fully refundable deposit now. While you're filling out that form, I'll tell the Pontiac Mechanic about your situation and connect you two.
