ETA 9362 check electronic module

[Cmmb8519]

Dear all

My first experience servicing a quartz watch after servicing as an hobby my mechanic watches for many years. This is an old Certina that was given to me by a friend, with  a ETA/ESA 9362 movement.

Before service I put a new battery and the watch was working. After servicing the movement stopped working. i understand that there might be a lot of reasons for this (including the fact that I used technics and oils from mechanic movements on this one  ), but at this stage I would only need to check if the electronic module is good. Don't have a quartz tester but only a multimeter.

You will see on the photos that the battery contact is broken and needs soldering. With the battery in the movement I can confirm that the electronic module had power (1.57v).

Question: what basic tests can I do with a multimeter to confirm that the electronic module is good? how to check if the coil is good and if there is pulse in the electronic module? what contacts should I use to test it? (I saw some videos on you tube but was not able to find the specific test procedures for the ETA 9362).

Any information to help me check if the reason for the movement to stop is on the electronic or mechanic part of the watch is much appreciated.

Many thanks

Hi other than testing the coil without the proper tools it will be difficult.  If you +an rig up an external supply and attach it to the cut block you may be able to pick up the pulses on the chip if not on the coil.

i have attached the parts sheet for the watch 9362 which gives you the part number of the cut board assembly, whether this part is still available or not , who knows.

Thanks very much watchweasol.

A couple more dummy questions. What do you mean by 'cut block'? and to see if there is pulse on the chip, which contacts on the chip should I connect the multimeter?

Many thanks
