POSSIBLE PROBLEMS/SOLUTIONS
Some of the more common problems with the remote-
battery switch could be:
1. Engine will not crank over- The re-
mote battery switch is in the "off " posi-
tion. Reposition the remote battery selec-
tor switch to the "on" position.
2. Remote battery switch in "on" position but en-
gine will not crank over- Make sure the universal bat-
tery switch on the battery management panel is "on" to
provide power to the helm. Check the appropriate battery
connections for corrosion and tightness. Check battery
with volt meter as described earlier and a hydrometer if
needed. If battery is determined to be weak press the bat-
tery parallel switch to crank the engine over or start the
generator which will initiate charging of the weak bat-
tery.
TYPICAL RELAY FUNCTION
The previous management system drawing shows a relay
(located inside battery management panel) wired between
each remote battery switch and the appropriate univer-
sal "ON-OFF" battery switch at the battery management
panel. The purpose of the relay is to provide a complete
circuit for the remote battery switch. When the port or
starboard universal battery switch on the battery manage-
ment panel is activated the remote battery switch circuit
is closed allowing the appropriate engine to be started at
the helm. The relay closes when the ON-OFF universal
battery switch is energized.
In theory, the relay switches "on" the ground circuit of
the electric battery switch not the "hot" side.
POSSIBLE PROBLEMS/SOLUTIONS
1. The engine does not crank over.
Relay is defective causing an open
ground circuit- Open the battery man-
agement panel and by-pass the relay by
pulling the wire off the 87A relay terminal and touch it to
the 87 terminal. Have someone crank the engine at this
point (Stand clear of any moving engine parts). If the
engine cranks contact your closest Regal yacht dealer for
replacement parts.
2. The engine does not crank over. Check relay for cor-
rosion or loose connection.
