1. BEP Thruster Battery Switch Failures and

Troubleshooting Guide

We have received some reports of BEP thruster battery switch failures. After investigating

this issue we have determined these battery switches can fail to connect over time when

the thruster controller switches are pressed.

Nature of the Failure

The battery switch, over time, fails to connect when the controllers on the switches are

pressed. The battery switch is sensitive to differences between the reference ground, a

black wire, and the switched ground, a red wire. When the switching voltage between the

two grounds exceeds 0.8 volts of DC current the battery switch will try to disconnect while

in the auto mode. Two contributing factors can be loose wire connections and a long

length of the circuit from the switch to the relay. We have included step-by-step

instructions to assist in the correction of failed thruster battery switches. In the event you

encounter a Meridian Yacht needing this correction, please telephone our Customer

Service team to obtain an authorization.

Troubleshooting Guide

Imtra Corporation has reported a significant number of Docking On Command (DOC)

controls returned to them as defective that, when checked, tested good. In an effort to

assist our dealers in accurately diagnosing the source of failures in the DOC system we

have also included with this bulletin a troubleshooting guide for our thrusters. In the

event the source of a thruster problem is not able to be identified, please telephone or e-

mail our Customer Service team for assistance before ordering replacement parts.

Meridian Thruster Battery Distribution System. Basic Operation of the thruster battery switches is accomplished by remote. By depressing both “on” switches at the controller the switches are closed connecting the batteries to the thrusters. The Controller is powered from a fuse connected to the line side of the Bow thruster battery switch. When energized it provides a 12V signal used to trigger a relay. Refer to Figure 1.
