hey all,

my car will start with a jump, and all electrical works great while the car is running, if i turn off the car starter solinoid will click, but not start, car is in park... the battery terminal connector on the positive side looks a little shot out but it is still intact.

at first it would crank a bit as the starter would slow down during cranking to a halt.

It did the same thing a few days ago which made me assume the battery i bought in the car was toast, I put in my healthy w116 battery to see if she would crank, she did and drove fine for a day. Im becoming ever more suspicious of that shotty battery terminal connection...

have a multimeter, where should i start troubleshooting this?
