1988 560sel no crank/turnover but battery good
 

Hi all,
yesterday I was leaving work and went to start, Engine turned over couple times and just went silent, No groaning, just stopped as if I had removed the key from ignition. Checked a few things but getting dark so I got a ride home. any thoughts where to start?

Thanks

Flat battery or battery cable issue is where I would start.

I always keep one of those 'free with coupon' Harbor Freight DVOMs in my vehicles just in the event I need to do a quick charging system diagnosis or check something for continuity.

Fully charged battery is about 12.60V and fully discharged around 11.7. I try to replace batteries after the free warranty replacement period is over. Which is every three years for me. Weather fluctuating between the low 100°F and upper teens is hard on them.

Good luck and keep us posted.

I would take a hard look at the battery cables also. I've seen them look perfectly normal until I took it off the post. Ugly city!!
