Polyvend 453 snack problem

[Lee@BIGBAPS]

I have a shelf selling £1 large chocolate bars but they were slipping under the spirals so I took the shelf out and turned the spirals back.

I put the shelf back in, reconnected same as before but now nothing on the shelf will vend but if I test a selection on the B shelf, they will vend as normal but it also starts pushing out my E shelf products, E is the shelf I took out.

Also testing A2 will turn the A0 spirals but only halfway around. A2 will vend the product as normal.

Ideas anyone? I'm not experienced with snack machines.

Fixed it.

There's 11 pins on the PC board for the shelf but 12 openings on the wiring from the shelf I connected it wrong.
