Equipment Operation
6-23
The DVSR uses a LED type light that indicates that the DVSR is
closed and is sending a charging current to the batteries.
If the LED light stays on after the engine is turned off do not panic.
This is a normal condition. The residual battery voltage due to battery
charging has not yet dropped below 12.8 volts for the DVSR to cut
out.
