Getting an ML7

[DMRParticipant @dmr]

Note to JF1, Peters other photos in his album show a capacitor box.
OK Peter, definitely single phase so has 4 connections and that vacant hole is where your 4th wire should be but……….The other 3 wires may have moved from their correct spot and even deeper into it the capacitor may have been messed about with. Determining what those feint marking by the terminals are (and they obviously exist) does not help much as different manufacturers used their own combinations and even changed them after a company take-over. From studying form on the internet they are most likely A’s with or without a following number and Z’s with or without a following number if that helps you pick them out. Also from the web, the blacks are start winding and the red are the run winding but you really do need an electrician or someone with a meter and basic knowledge to prove the windings continuity and for short circuits to earth as JF1 says. Take the motor into that Ilminster shop (just the motor) and slip him a few quid. It will take him 5 minutes tops to instantly tell you if it is any good or not and what the winding connections are and take it from there.
You need a brass screw and nuts, M6, 0BA or similar in that vacant hole. Do not use a steel one.

One reference I have come across for Gryphon says the starter winding and running winding have there original labels of A1, A2 and Z2, Z3. I hope that helps further. I used to live in Bridgwater but am in Chester now. Otherwise I might have come for that refreshment.

I really do appreciate all the recent advice, especially the patient encouragement to have a go at fettling the current motor. But this morning, the caution about playing with mains power and what can be expected from old equipment is winning.

I can't afford it on this months buget, but wait 3 weeks and I'll get a new motor and switch. Meanwhile I'll get everything else cleaned & sorted so its really ready to roll when up to date power is installed.
