AY 160 credit unit issue

[prime]

Hi guys my credit unit has just stopped, cleaned all contacts and made sure all connections are good. I have a free credit unit so i removed it and tried coins, When i add a credit i see the plunger fire a pin and move a copper contact, after that nothing. Im not sure what is supposed to happen next. Could this be a faulty cap? any help appreciated.  pete

Age is a scary thing, i forgot i had to change d connections of electrical selector to use new free play, i was trying the credit unit but this could not work with this setup, sorry for the waste of time pete
