This is a UK built replacement Speed Control unit for an E-Caddy, Masters or Slazenger electric golf trolley.

The Speed Control unit is located under the tray that holds the battery in place.

The classic symptoms of an electric golf trolley that requires a new speed control unit are:

  • The trolley will only go at one speed, usually full speed, or
  • The trolley is dead, or
  • The trolley is intermittent, ie it goes then cuts out.


If the polarity has been reversed on your trolley (ie a battery has been connected 'black to red' and 'red to black') then 99% of the time this will damage the speed control unit.
