Ami Rowe Jan Diplomat : cannot identify the problem

[pierre]

Hello from France !

My name is Pierre and I live in SW France, nearby Bordeaux.  Earlier this year, on my 50th birthday, friends offered me an Ami Rowe Jan Diplomat.  It hasn't been restored, therefore it's been keeping me busy during the COVID lockdown !

I'm asking for some help as I've been searching and reading the service manual again and again for days but I'm stuck    

Here's what happens.  I press a letter, release it, so far nothing else moves.  Then I press a number and I see the latch coil move left and at the same time the R1 relay moves up.  Next I release the number button, the latch coil and the R1 get back to their initial position, and then nothing else happens.  Using strips of paper cut in a business card, I tryed to clean the R1, R5, S1 an S2 relays, but it didn't change anything.

Hello Pierre.
I don't have a JAN manual but I'm fairly sure that it's similar in operation to the JBM (Tropicana). When you have established credit, the latch relay R1 should pull in which in turn energises the latch relay. When you press the letter pushbutton, it should stay down (latched). When you press the number button, it should also stay down. At this point with a letter and number button latched, the search motor should start.

There will be schen-a-grams in the manual explaining each step in the operation, maybe in the troubleshooting section.

Hello Norman,

Thank you for your answer. I re-read and rechecked everything and I finally found the problem : there was no credit. Now I feel stupid ...

Hi Pierre,
Don't feel too bad about this-- I have driven many a mile (or "klick", to you !) just to turn on a "power switch", or push a "reject button"!
