That part on the rectifier assembly is an MOV to clamp surges.it has a disc capacitor, brown thing, I think its a disc cap? Not 100% Sure!

Just a thought, have you checked the two motor connections are good and tight, no frayed wires, etc. I used to work on cars, and the number of faults due to bad connections, frayed wires, oxidation of terminal surfaces, etc, was truly amazing. So worth a look.

Capacitors should be fine. You could replace them if you want.
I'd remove the potentiometer and measure it. You got odd readings from it.
Go to uk.farnell.com and search for TYN608 and MPSA42 They have them in stock and together they are under £1.
MPSNA42 Their are loads of different type Shenion, which one is it?Capacitors should be fine. You could replace them if you want.

The orange and black things sound like Zener diodes, but these generally have a letter 'z' somewhere in the code printed on them, unless they are very small.
Your picture states 82k 850 24 for what looks like one Zener, on your R/H side of the picture. I would guess this is a 85 Series Zener at 24v 82kohm values.
Farnell will sell these too, at a few pence.
I can't see another one. The thing at the top marked T4148 is a standard signal diode, the same as the much more common 1N4148, I believe.

ive removed the pot and tested it. Touching the two end pins I get a constant reading of 8.4 and it dont move, If i test the centre pin with either of the two end pins, I get a linear reading from 0 upto 8.4. and if I try the other end pin and the centre pin, I get the same reading, vice versa I suppose.
Im guessing this is fine then?
They are all the same, just made by different manufactures or different packaging (individual parts or reels.)MPSNA42 Their are loads of different type Shenion, which one is it?
If you want you can test the Zener that's still in there. It is 24v, and a Zener over around 12 - 13v will generally behave like a normal diode if you use the 10k ohms range. That is, it should show nothing in one direction, but show passage of current in the other. Even if it tests good, for what it costs you can still replace it, and keep it as a spare.
