ELECTRICAL TROUBLESHOOTING - GENERAL OVERVIEW
The following pages are compiled to aid diagnosis of
electrical faults, based on the Beta 10 - 115hp range of
engines. If your engine was built before July 2005, contact
Beta Marine for the relevant electrical trouble shooting
guide.
NB: our standard control panels are for earth return
installations only (where battery negative cable is
connected directly to engine ground). For insulated earth
(where battery negative cable is isolated from engine
ground) different harnesses, alternators, switches for oil
pressure and engine temperature are fitted.
Heat Exchanger Engines
Standard heat exchanger cooled engines are supplied with
a single starter battery alternator, a secondary domestic
battery bank alternator is optional for the Beta 30 and
above.
3.5kVA, 230v, 50Hz Travel Power alternators and inverter
are optional for the Beta 35 and above. For the Beta 43
and above a 5kVA variant is additionally available.

Keel Cooled Engines
Standard Greenline keel cooled engines are supplied with
a single starter battery alternator, a secondary domestic
battery bank alternator is additionally included as standard
for the Beta 30 and above.
For the Beta 38 and above, it is possible to specify both
a secondary domestic battery bank alternator & a 3.5kVA
travel power alternator & inverter, 5kVA for the Beta 43
and above.
Both the starter battery alternator and domestic battery
bank alternator work independently of each other, when
equipped if the domestic battery bank alternator is
disconnected, the engine will still run correctly but the:
• Domestic charge warning lamp will not function
• Warning buzzer will remain on at all times.
NB: The two way plug on panel loom will only have a
corresponding socket to connect into from the engine if
a 2nd alternator is fitted which requires this connection.
Engines with only one alternator do not utilise this
connection.
