or closed. It only draws power during activation. The relay is sealed against the
environment and is designed to withstand the shock and vibration experienced in the
most severe RV, or boat applications.
The Battery Disconnect system connects directly to the vehicle’s positive battery terminal.
Inadvertent shorts across the battery or to ground, may cause severe damage and injury.
Use extreme caution when working with these wires. Always wear safety glasses when
working with the battery connections.

THE RELAY - How It Works
THE RELAYTHE RELAY
The Battery Disconnect Relay is a mechanically latching switch. It operates by the
momentary application of battery voltage to the coil terminals in one direction for latching
(closed), or the other direction for unlatching (open).
To close the relay, +12 volts is applied to the “I” terminal and ground to the “S” terminal
of the relay. When this is done, the plunger is magnetically pulled into the solenoid coil
and the contact washer connects to the contact studs, making electrical connection. While
this happens, the rod magnet, suspended below the plunger in a plastic holder, is attracted
(opposite poles attract) to the plunger, by the magnetic field. It swings into position at
the end of the plunger (
plunger gets pushed back by the return spring, but is blocked by the magnet holder. The
contacts remain CLOSED.
To open the relay, +12 volts is applied to the “S” terminal and ground on the “I” terminal.
When this is done, the plunger is again pulled into the coil. However, since the magnetic
polarity of the coil is reversed, the rod magnet is repelled (like poles oppose), and swings
out of the way (

gets pushed out by the return spring, breaking the connection between the two large
terminals.

While switch is engaged, check for voltage across
the coil terminals (+ on the ""I" terminal and ground
on the "S" terminal). If 0 volts, replace panel, if +
