Am using Mercury sequencer in Carf P-47 so - mode 1 but with a single set of doors i.e. all doors driven by one Jetronic door valve (gear is driven by Jetronic valve also). I have carefully set up the sequencer now on two occasions and on each occasion it initially works perfectly i.e. gear correctly responds to Tx switch position and everything happens in correct sequence. If I switch the PB off and then later switch it back on everything works ok. But, after about four or five times when PB has been switched on and off, the sequencer then goes out of control. My Tx will not come on unless the gear switch is in the down position. Before switching on I always set the gear in the down position with doors open. When I now switch on, the gear doors close first and then the gear retracts. So not only is the sequencer not responding to the correct Tx switch position, it's actually working out of sequence.
Can you give me any insights as to why this is happening please?
