Volcano (Gottlieb, 1981): Common Issues and System 80 Replacement Boards

Is your Volcano pinball machine by Gottlieb (1981) freezing, resetting, losing the flippers mid-game, with solenoids stuck on at startup, or displays fading? On this Gottlieb System 80 pinball machine, everything points to the CPU/driver boards, connectors, and grounds. Here is a summary along with compatible System 80 replacement boards.

Volcano (Gottlieb, 1981): Overview

  • Type: electronic (solid state, with speech)
  • Theme: volcano, adventure

Common Issues on the Volcano (System 80)

Like all Gottlieb System 80 machines: aging CPU/driver boards, crashes and resets, slam tilt, failing displays, faulty grounds and connectors, leaking battery.

Volcano-Specific Issues (Forum Reports)

  • At startup, the ball feed and kicker stay energized (with a zero on the credit display): risk of burning out the coil or blowing the fuse if left in this state.
  • Connectors: this is THE weak point of System 80 — one user traced 99% of their issues to loose pins on the power supply board.
  • Displays receiving only ~3 Vac instead of 5: clean the connectors (with an eraser) to remove oxidation.
  • Ground mods recommended + redo all connectors at the same time.
  • Dirty switches under the playfield = freeze; intermittent flippers (especially when the ball comes up from the subway).

Resets, grounding issues, solenoid control problems, and weak power supply all disappear when upgrading to the GottFA80_Plus (all-in-one board with rebuilt power supply); the Lisy80 helps locate switch faults.

FAQ — Volcano Gottlieb

Why does my Volcano freeze mid-game?
Often dirty switches under the playfield or faulty connectors; the Lisy80 helps with diagnostics, and the GottFA80_Plus makes the whole system reliable.

Solenoids stuck on at startup?
Turn off the machine immediately to avoid burning out the coil. A rebuilt driver board (Godri80) or the GottFA80_Plus fixes this issue.

My displays are dim?
Clean the connectors; if the problem persists, the rebuilt power supply of the GottFA80_Plus restores proper voltages.

Do I need to replace the battery?
Our boards operate without a battery: no more corrosion.

How long does it take to install a replacement board?
Installation is Plug & Play: just a few minutes, no soldering required, with free tutorials and support.

Does a battery-free board retain settings and high scores?
Yes. Modern replacement boards use NVRAM: no battery, no corrosion, and settings are preserved when powered off.

Step-by-Step Diagnostics

  1. With the power off, visual inspection: look for any battery leakage or corrosion on your Volcano's MPU; remove the NiCad battery if still present.
  2. Power supply: measure the 5V and verify it reaches the MPU (reflow the solder on the regulator or Q1 if the voltage drops).
  3. Grounds: apply the ground mods between boards (CPU, driver, power supply, sound).
  4. Connectors: re-pin the oxidized Molex connectors, especially the MPU-to-driver board connection.
  5. Displays: never plug or unplug a display while powered on; test with a known working display.
  6. Final test: check startup, credits, solenoids, and displays; if needed, contact our free support.
