Its about 11 years old and needs a replacement capacitor (not supplied).  
It functions fine with small loads but struggles to engage with medium-large loads.  

If someone wants to pick it up (from Auckland) and repair it themselves for use or for sale let me know.
There is even a Youtube video instructing how to do it.
