I changed my A154 A155 (2 modules) from one rack to another and I think one of my A155s broke

Something wasn't working 

Ithoght it was the connection to 154 board. I connected the a-154 board to ST1 instead ST2 on the first sequencer.

It was that I had connected wrongly one of the 10 pin connectors to the board, only half of the pins was connected.

I connected everything but... 

the sequencers were doing weird things

to summarize, after several trial error setups

the sequencer that was sequencer 1 when  I connected wrongly does weird things

the other sequencer works ok as first sequencer connected to the A154, and if I connect both, both do weird things

I've sent a mail to hardware@... with an explanation of what happens and I will be sending the A-155 for repair

Here is detailed explanation

A-154 with clock running and manual on/off in Off

If Faulty A-155 connected as first sequencer 

I have to switch on/off twice and then the sequencer starts from step 1 to 4 then 8 then 1 and stops

If man is set as on in A-154  when I click on the A-155 module clock button

starting from step one light on

click — step2

click — step3

click — step4

click — step8

click — nothing - stays in 8

click — nothing - stays in 8

click — nothing - stays in 8

click — step1

If I connect good A-155 as first and only sequencer connected to A-154 

everything works OK

If I connect good A-155 as first and faulty A-155 as second

both sequencers go to 1-4 then 8 then 1… as when the faulty one is connected as first

it seems the problem is in the A155 not in A154

any ideas

thanks in advance
