Electrical Fault Finding – Non-Beta Panels
Engines can be supplied wired up to suit VDO switch
senders, usually fitted to a non-Beta control panel. If so refer
to our wiring diagram 200-60971/01 (also part number for
replacement harness)
• Loom is configured differently in the 11-way plug to
accommodate the extra wiring.
• Small brown wire (battery sensed alternator feed) fitted
with bullet connection beside harness plug.
• Oil pressure and water temperature switch / senders fitted
to engine, requiring individual connections for driving
gauges and warning lamps.
Electrical Fault Finding – Extension Harnesses
Some installations require one of the panel extensions 11
way connectors to be removed to allow the cable to be
passed through bulkheads etc.
If any panel problems are experienced, after this may have
been carried out, visually check all 11 way connections on
engine harness to panel extension (and panel extension to
panel on C 'Deluxe') to ensure wire colours to each terminal
match up to the correct colour in its corresponding terminal.
Electrical Fault Finding – Insulated earth
If your application is wired as insulated earth return and the
engine will not operate correctly, always check starter battery
negative is connected to the correct terminal on the isolating
solenoid.

WK Warning lamp
Extra attention must be given to black (ground) and
black/blue (tacho), also brown (switched positive to
alternator) and brown/yellow (charge fail) as these
connections are harder to distinguish between in poorly lit
areas. Whilst doing this check integrity of each connection to
ensure terminals have not become damaged. Once checked,
re-fit cable tie around each connection to keep them secure.
It should be connected to the terminal which is also used for
all the small black wires, NOT the terminal with the single
black wire connected directly to engine ground.
