Starter Motor Problems

Hi, finally got around to fixing my solenoid problems on my starter motor, as posted on here last year. The starter now works as it should except it does not have the power to turn the engine over (it does but very slow and laboured). If I remove the plugs (not as much resistance to turning over) it then turns the engine over as it should.
I have checked the tightness of all the connections and cleaned up the earth strap, engine to body. Could this be a case of dirty/ worn bushes within the starter?
Or, the engine had not been turned over for about 4 years previous to this so could it just need freeing up a bit i.e. keep turning it over with the plugs out?

cheers
 
Could be

Poor power supply / low battery

Weak earth

Poor contacts in the solenoid

Worn carbon brushes inside the motor

Have you tightened the starter bolts - this is important for earthing

If you have some ramps/pit and jump leads - car not in gear !

1st bypass the solenoid by connecting 1 jump lead from the power feed to the starter contact.

2nd take the battery off the car and connect the earth to the engine and +ve straight to the starter
 
I would say check the power supply.

I have bee working on a friends car this month which could be reluctant to turn over. the problem was the +ive cable the supplies the starter. In this case the cable had corroded under the pedals. the outer layer of copper wires had turned to green powder and there was a very power connection. this cable is terminated to the stater so check it looks good.

I second the method that keanej suggests, but first lift the drivers floor mat and check the cables there. then try more earthing for the
engine block by connecting the jump lead to the engine and a good earth. also make sure that the battery is in good order.

Thanks for the replies guys. It has given me some things to check.

The battery is pretty new and was in use on a BMW 528 and it worked fine on there, so that should be ok.

I tried jump starting from another car and got the same result.

I have connected the battery directly to the motor and earth to the engine and still no joy, although I cannot remember if I disconnected the thick cable which runs to the battery, so if there is a fault in that, then that could still have caused the problem.

I will try that again and if that does not work it is looking like the starter motor itself.

cheers.
