Honda VT750CD ACE
2.0 The VT750CD Electrical System ‐ A Brief Overview
2.1 Introduction
The Honda Shadow VT750 CDX (ACE) has a basic 12 volt electrical system with a frame ground. The battery is
a sealed maintenance free unit and the charging system is a 3-phase Permanent-Magnet system. It has an
electronic Regulator/Rectifier which can control the output from the 3-phase alternator as required and the unit
is completely sealed and non-repairable. The ignition system used on the ACE is a Digitally Controlled
Transistorized Ignition System (TDI) which uses an ignition pulse generator to send a trigger to the Ignition
Control Module (ICM). The ICM then controls when the ignition coils will fire the spark plugs. The ACE has two
ignition coils (One for each cylinder) and each coil has two outputs for the two spark plugs in each cylinder.
