Need some help here...trying to see if I started I bought used works....I took some jumper cables and connect from my car battery to the motor....it is getting 12.86 volts....I connected both the hot and ground wires.

Should the motor have spun?

Re: test starter

If you connected it properly then yes it should have ran. If you have doubts, take it to your local auto electric shop.

Re: test starter

ok this is nagging at me.....i tried testing the starter and could not get it to spin....took to auto parts store and they said it was fine???? Any suggestions on what I could be doing wrong. I am taking a normal set of car jumper cables...connecting hot to the bottom screw on the starter and connect that to hot side of battery....connecting ground to battery and to grounding block on the starter.....i am measuring 12.86 volts at the starter with my multimeter...what am I missing?

Re: test starter

Sometimes it takes a 'strike' across the terminal to get the solenoid to engage. Try not to hook it up direct, but touch it with your jumper. Hope that helps

Re: test starter

It sounds like you are connecting the +12VDC side of the battery to the starter solenoid, instead of the starter. Is that possible? Are you working on a MerCruiser?

Mercury 35 hp 1987.....i have just the starter motor no selenoid attached. Is the issue I am connecting directly to the starter motor?

Re: test starter

OK, That should work. Maybe the ground point you picked has too much paint? is that bolt hole threaded? If so, insert a bolt and ground to that.
