2.6.2. WIRING
Cable SP-1 consists of 3 sections terminating in a connector that plugs into CN1 on the CPU board.
In the interests of simplicity, these 3 sections are described separately below:
SP-1: Internal connecting cable – machine control
CPU – Alternator interface board
CPU/CN1 Signal Color Alter. board/
