- Vacation America, December 2004, model 9000.
3 Technical Info
Owner's Manual and schematics for Vacation America home model pinball.
File:Vacation America manual.pdf
Dimensions: 74" high by 53" long by 25.5" wide. Weight: 200 pounds
4 Problems and Solutions
4.1 Power Problems
The power transformer, power supply board, and fuses are all located on the bottom floor of the machine. There are four fuses on the power supply board:
- F1 8 amp slow blow for the +45 volts to flippers
- F2 5 amp slow blow for the +24 volts
- F3 5 amp slow blow for the +38 volts to coils
- F4 3 amp slow blow for the +12 volts
There are a total of seven power indicating LED's on the power supply board:
- D1 indicates +45 volts present
- D2 indicates +24 volts present
- D3 indicates +38 volts present
- D4 indicates +12 volts unregulated present
- D5 indicates +5 volts present
- D6 indicates +12 volts regulated present
- D7 indicates -12 volts present
Bridge rectifiers.
- BR1 GBPC25-02, 25 amp 200 volt, is for the +38 volt coils
- BR2 GBPC25-02, 25 amp 200 volt, is for the +24 volt circuit
- BR3 GBPC25-02, 25 amp 200 volt, is for the +45 volts to the flipper coils
Electrolytic filter capacitors.
- C1 10,000 uf @ 50 volts snap mount is the filter for the +38 volt coils
- C2 10,000 uf @ 35 volts snap mount is the filter for the +24 volt circuit
- C3 10,000 uf @ 50 volts snap mount is the filter for the +45 volts to the flipper coils
4.2 Solenoid Problems
4.3 Lamp Problems
4.4 Switch Problems
4.5 Display Problems
4.6 Sound Problems
4.7 Flipper Problems
The flippers operate on 45 to 50 volts DC from the power supply board. They are modern Stern units with normally open end-of-stroke switches. Flippers are driven from driver transistors.
Driver transistors:
- Q110 Right Flipper "Flip", type IRFZ34
- Q111 Right Flipper "Hold", type IRFZ34
- Q18 Left Flipper "Flip", type IRFZ34
- Q112 Left Flipper "Hold", type IRFZ34 (Note: mistake in schematic calls this right flipper hold)
4.8 Pop Bumper Problems
4.9 Slingshot Problems
Slingshot driver transistors (located on playfield PCB 1):
- Q17 Left Slingshot, type IRFZ34
- Q19 Right Slingshot, type IRFZ34
4.10 Opto Problems
The optos operate on +12 volts. If the +12 volts is bad or missing, none of the opto switches will work. Opto unit itself is type TCRT5000 and uses a type 2N4401 transistor with it.
