I'm supposing the condensors are surge absorbers (as technical as I can be  ) to protect the control unit. Maybe Trevor or Harvey could offer better insight.
I would suggest checking for proper grounds and power. The tricky part is that it may be an alarm module issue. Maybe someone would be kind enough to let you borrow a spare. (hint, hint...)

The RHD model does not have the alarm module that you have, So can't help there.
Beav, you are not often wrong, but you are right again
. The condensors are to suppress the spikes produced by the brushes in the motors.
Lee if the input wires to the control modual have zero resistance between them, It would appear to me that it's died.
