Astrosphere Mcp Mb 07241 5 - Board Diagram

| Pins | Signal | |------|--------| | 1, 14 | +5V encoder supply | | 2, 15 | A+ / A- (Channel A differential) | | 3, 16 | B+ / B- | | 4, 17 | Z+ / Z- (Index) | | 5-13 | Spare grounds | | 18-26 | Shield drain |

Symptom: Smoke, board dead.
Diagram location: J1 pin 1 → 10A fuse (F1) → D1 bridge.
Fix: Replace fuse. If trace is vaporized, solder a 14AWG jumper wire between J1-1 and D1 anode. astrosphere mcp mb 07241 5 board diagram
