Thank you Kind regards

Hi all, I have inherited a 18v solo battery mower, run for 30 seconds then stopped? Model MLM 2834 li
These are the things done so far :

Checked battery (Good)
Checked switch and cabling (good )
Used continuity meter to check again

Stripped out motor checked cabling

Set up motor switch and battery on bench and checked again ... no go either

I want to check motor direct but not sure what cabling to use ? Which one is neutral and which one is live ?
There is a sealed module unit, how does one test this ?

The dead man's bridge is fine also

Any suggestions the cables to the motor are yellow blue and green

Is there a tech repair  manual for these ?
 The only thing I can come up with is the electronic sealed unit may be faulty ?
