I gather the dealer checked for abnormal parasitic drain, as well as confirmed that the 12v battery IS getting charged during driving, yes?
Thnx for your quick reply. Yes, dealer tech said they checked for drains, and adequate charging voltage. The tests they conducted seemed extensive.
I suppose I need to get one of those meters. Like intermittent electrical problems everywhere they rarely show up when at the shop. Doh.
I looked on Amazon. Plenty of meter options. Do you know if there is a model that comes with memory? I didn’t see one. Would like to let it monitor voltage for, say, 24 hrs then download the data. The 12v socket is way down in the center cubby. Impossible to see while driving. Driving safely, that is.
Also, I like plots and graphs, TBH.
