I have a 2009 Bennington with a 5.7 GXi. It beeps at me every 60 seconds, I timed it yes. I checked battery voltage with and without engine running thinking it was alternator. 12.5 engine off, 14.0 engine running. I check engine oil level. Any other ideas on what I need to check? I did have a Batt Voltage display across the tech gauge one of the times I ran around the lake. Any other troubleshooting advise? Anyway to plug the engine into my laptop and read error code?
