I could use some help figuring out where to start diagnosing a no power problem. 2009 R56S that doesn't get driven much anymore. Went to start it and no dash lights or chimes. Battery was discharged, so I charged it overnight and it did take a charge. Insert key FOB and still nothing. Tried the fob from another 09 just to see if I'd get the "wrong fob" warning light and still no lights no chimes. Any suggestions on where to start diagnosising this issue?

Thanks,
Sam

 

What is the current voltage reading between the two battery posts?

 

Thanks for reminding me to check my work and possibly my bifocals.This morning after having charged overnight I read 12.7 volts. It was actually 2.7 volts. Doh! Problem solved!

Thanks again,
