ELECTRICAL TROUBLE SHOOTING - ALL CONTROL PANELS
Before investigating any specific electrical problem,
always check:
• The connection between the panel harness and panel
loom. It must be clean, dry and secured with a cable
tie.
• The start battery is connected to the correct terminal
on the starter motor.
• The domestic battery is switched on and connected
Problem
No warning lights or buzzer functioning, engine will not
start or stop
Non function of warning light. The water temperature
light will not function unless engine is overheating
or there is a wiring fault
Water temperature warning light on when engine is not
over temperature (Not B or C deluxe panel see table on
on following page)
to the correct terminals for the secondary domestic
battery charging alternator.
• The battery connections and inspect the condition of
cables from the battery to engine. If in doubt measure
the voltage at the engine.
• If there is a starter alternator charge problem, measure
battery voltage with engine off and again with engine
running, if there is an increase the alternator is
functioning correctly.
Possible Cause and Solution
• Battery isolation switch in off position - switch on.
• Starter battery discharged - charge.
• Engine fuse blown - check fuse (above starter motor or
flywheel housing) and replace if necessary.
• Check for wiring faults.
• Disconnect switch wire to non-functioning light: green/
blue –water temperature
brown/yellow –alternator charge. Reconnect wire
temporarily to another warning light that is functioning;
if wire switches light on replace faulty light.
• Disconnect positive feed to non-functioning light.
Reconnect temporarily with wire from another warning
light that is functioning, if wire switches light on rewire
with new connection.
• If none of the above, check continuity of connections
from panel to the engine.
If engine is cold:
• Faulty wiring, check connection and continuity (small
green/blue) from switch to panel light. Ensure this
connection is not shorting to earth (ground).
• Faulty temperature switch - if light switches off on
If engine is warm:
• Switch wire connected to large sender terminal of
switch/sender unit. Remove and refit to smaller
(switch) terminal.
