Not all single phase electric motors have the wiring compatible with reversal. If its 3 phase, then a VFD would be the simplest solution.

If single phase Check the connection box to check both windings are brought to the terminal connections before buying a suitable switch.

If it is 3 phase best to get a FWD/OFF/REV switch suitably rated for the motor current, best to only use the switch with the motor stopped.

There are numerous switches that will do this, Dewhurst and santon, Etc Will work on single and 3Ph. If you know HOW to wire it ! Noel

Very much in agreement with Robert, here. Old mart’s wording would have been better to say that a VFD, while (perhaps) a little more expensive might be a better solution.

A VFD would be my choice, simply for the added programmable features – such as soft start, easy remote operation additions, etc.

Until we know the motor type, we are all guessing.

Alpine Major, eh? That will be a Sunbeam Alpine with a Fordson Major engine, I guess?

Single phase ! Could be cap start , cap run. Is there a wiring diagram on the lid of the terminal block ? I can't make much out on the spec plate or from the jumble of wires in the junction box. IF there are 4 wires coming out of the rubber grommet then it should be easy once you identify the start and run windings. Are there any letters or numbers on the grommet beside the wires ?

Tim . the major engine will be toooo heavy on the front end, just buy a tiger and be done with it ! Noel.

You would need 2 fuel tanks if the Fordson Major engine was used and be prepared for a reduction in power.

open it up

try to wire and run it in reverse, use a RCD to do this

if it runs happily in reverse then you need a reversing switch, I might be a bit of a bodger boy but I would 100% recommend a proper one which are 20-50 quid

When the forward and reverse switch failed on the museum's drill mill failed, we just replaced it with a no volt on off switch. When I got a 3 phase motor and VFD for the Tom Senior, I could have programmed reverse, but couldn't think of any need. We wilkl not ever be doing any power tapping.

Two run windings! Hmm.
