I dragged an F-14 out of storage ("it ran when parked") to shop it and rotate it into the herd. There a few things going on.
The good news is the displays are bright - the lamps work - the sound is perfect - all switches work - flippers work.
The bad news is within a few seconds of turning on the 2.5A fuse above the flipper power supply blows (the VIO-YEL circuit) probably as it is doing a ball search and fires a coil. With the fuse removed the games boots and runs in attract mode no problem.
I tested all coils and none were shorted. All were about 5 ohms except the two diverter coils - they were about 15 Ohms.
The power supply seems fine (I think):
+5 VDC = 4.9VDC
+12 VDC UNREG = 11.6 VDC
-12 VDC UNREG = 14.1 VDC
-100 VDC = -103.8
+100 VDC = 103.4
The VIO-YEL voltage out of the flipper power supply the fuse is 75.5 VDC
Some of the flashers work but also lock on the #89 flash lamp located under the left side ball guide in-lane.
When in Coil test there are some anomalies - mostly on the "C" side. A spreadsheet is attached with the results in coil test.
Thanks in advance!
