Hi,I'm in the process of putting to work 100%an AFM pin.Last thing to finish is the right jet don't working,switch works and make his sound.
First I don't have the 70 volts
Changed the Q 42 related transistor
Then I had the 70 volts in the coil
Still don't fire,not in test or in game
Then I changed the coil,still don't fire
What can be
Cpu?
Thanks for your time and help
Robert

Check that today
Thanks

Ribbons checked,no change
More ideas?

Maybe,I need to check,what can I do in this case
Thanks

Ok thanks,I report in the afternoon
Have to be something like that
Thanks
Robert

Ok,report
Voltage in coil is 70v constant
No sign of loose or broken wire from other jet to this one(right jet)
Jumped a cable from working jet to this one and still nothing
Running out of ideas
Thanks

Someone help!!

Q 42 was changed.(what transistors are those pre drivers)
Please guide me
Robert

Some one please!!

Sorry for the delay I had a mini vacation
Thanks for your help
Zaza I have the 70 volts on q 42 tap
Also grounded j113-4 (selenoid in question right jet)and it fires
What next
Thanks

That's is,is not like the manual,and no sign of something hacked,maybe then the q 42 is not its transistor
J113-4 grounded shoot the right jet (the one in question)
Thanks

Left column
11 left jet j133-1 q43
12 botton jet j133-2 q 47
13 right jet j133-3 q 42
??

Sorry guys my mistake
J113-6 brown/green is the correct pin for the right jet like the manual said
I jumped to ground this j113-6 and the right jet fires
So what next
Please some help
Robert

I think everything works,
I checked q 36 and is ok
Q42 is ok
Mostly probable u6 chip?
Thanks

Ufff
If not u6
What is other possibilities
Thanks

Recheck everything
115 v in q42 tap
6-8 v in led 5 of u6 when righ jet is in test
??
Thanks zaza

What next??
