I've discovered that the magnasave coil is no longer energizing. The voltage on both wires at the connector going in to coil are 6v. I've checked the fuses and looked at some of the past threads, but in those threads there was no power to the coil. I've done the basic checks on Q14 (without removing it) and these tests seem good. I've found the setup board on the underside of the playfield and it passes the 6v as mentioned above. I could really the help of someone who is familiar with this problem. I've been at it for a few weeks and am at wits end. I can't seem to determine if the circuit uses a relay. Also, how does the firing mechanism work? If there is already 6v at the coil, then does firing the circuit cause the voltage to jump? If so, what voltage should it be jumping to? Please forgive the basic questions as I am doing the best to learn how to help myself.

Terry,
Thank you for the explanation about the voltage drop upon activation. This clears it up some. When I hit the MagnaSave button I hear the affects and see the notification on the scoreboard, so I know it's triggering. This means I can skip the edge test, right? Also, if I see 6V on both sides of the transistor and neither goes to zero when the circuit is turned on, does that imply that the transistor is bad?

Magna save passes the edge test. The Solenoid table lists Q14 as the magna save driver, however, the "High Current Driver Board", Magna Save Circuit on page 65 of the manual has another transistor Q1 which has one side of the transistor going to the coil like you said. This is the board on the underside of the playfield that I mentioned in my OP. So I put the meter on that side of the transistor and fired the circuit and it remains at 6volts (or 6.5 from what I remember). Did I perform the test on the correct transistor (since it's closer) to the coil or should I also perform it on Q14 which is on the CPU board?

I probably won't have time to test it tonight. I hope to test the next few days and report back. Thanks.

I've discovered that the voltage is in fact, 70v and not 6. I made two mistakes. Mistake 1 was that I thought it was AC voltage but discovered it's DC. Also, I thought you could ground the meter to the silver PSU inside the cabinet. Only after using the grounding strap in the backbox was I able to determine that the voltage was DC. There was 70v on the outer pins of the molex at all times and 0v on the middle pin at all times (regardless of energizing). Going off of that, I discovered some bad traces on the interconnect board and hope to deal with that in the next week or two. I will report back. Thank you both!
