Hello all.
My ES starting resetting a week or so ago.I read up on the wiki about it and ordered a cap kit for the P/S board from GPE.I installed all the new caps yesterday,then checked and reseated all the connectors and it's still resetting.It just does it randomly,no coils fired at all,a few times it did with the ball still sitting in the shooter lane.I turned off all the other machines and have it plugged right into the wall also.
I read an old post where johnwartjr had to replace 723 voltage regulator IC to get rid of resets on his system 11,is this also a common part to replace when you rebuild your PS board?
Where else should I look to eliminate resets?
Thanks.

Your next step should be to measure the voltages and report what you measured.

You need to do some troubleshooting before you start replacing caps, ICs and other parts.

What does your +5 look like with a meter?

Too bad you didn't have a new meter?
