Hi Michael,
Probably a faulty oil sender, is the light on all the time, or flickering? I have been told they ‘degrade’ over time (my 3200 has had 2 new ones in nearly 14 years of ownership). As Rex says, try David Askew, then you will probably have to work your way around the Specialists to find one who has one in stock. McGraths would be next nearest to you.
Regards,
Graham
