The WAGDC-270 is designed to facilitate the installation of an additional battery on any boat to ensure that the engine will start after spending extended periods of time anchoring, or trolling.
COMPACT - Mounts directly to Alternator output post.
COMPLETE - Includes hardware, insulators and instruction manual.
CONVENIENT - Two battery reliability without the hassle of a confusing battery switch.

(this is how it mounts to the alternator)

The WAGDC-270 will work on any 12 volt DC-negative ground electrical system with alternators of up to 70 Amps output. It is specifically not recommended for use with higher output alternators.
The WAGDC-270 will mount directly on the alternator output or 'battery' post on alternators with a 1/4" or smaller diameter post. This mounting system fits Delco, Mando, Motorola, Prestolite and many other marine alternators. In addition, the WAGDC-270 may be flat mounted for applications where insufficient clearance is available, or for use on systems without alternators, such as outboard motors.
