El__burro:
Managed to remove the cover, one of the brushes is much shorter than the other. (see img)
Could this be the problem?

Thanks

El__burro:
by looking at the picture Ive realised that actually the brushes seem ok.
I took it apart and gave it a good clean, eventually it worked fine (tested on bike battery)
Once I put it back I have the same issue. I guess the battery (almost new) is to be replaced.
What should it read once i finished charging?

Thanks

mike the bike:
When you say "it worked", do you mean the starter motor spun when connected up or did it turn the engine over?
In other words,  was the starter motor back in the engine when you tested it?
Have you checked the starter solenoid by shorting out the big terminals with a spanner?  What was the result of that test?

El__burro:
I cleaned the motor, i attached it to the bike battery and it worked for a second, then very quickly it slowed down until it stopped.
Tried again but the motor was not responding.
I tried connecting it to the car battery but it wouldn't work with the cables so i decided to touch the motor case on the negative battery itself and the cable from the motor on the positive of the battery directly.
It worked fine.
Unfortunately when i do the same with the bike battery it drains it very quickly.
Battery sits at 12.7v
