The flipper fuse (in the backbox on these games) keeps failing.

Pre-solid-state flipper keeps blowing its fuse

Cause: The normally closed EOS switch never opens, so the power winding stays on.

Checks

• Push the flipper to full stroke and check the EOS gap.

Fix

• Adjust the EOS switch to open by 1/16" to 1/8" at full stroke.
• Replace the fuse.

Systems

• Data East CPU Version 1/2
