Having traced various electrical malfunctions on the centre switch panel and the repeated blowing of fuse #3 in the engine compartment fuse box to the security sounder in the offside front wing, I removed the sounder. The internal corrosion and the condition of the aged NiCad batteries make it clear that it will never work again. I can find no new sounders available; perhaps someone can give me a steer. Or can anyone tell me of a unit, perhaps from a later car, which can be substituted? The option is, of course, to leave the car, as now, with all the electrics working and the sounder plug sealed in plastic, but I would prefer to finish the job. Thank you, All. JohnC
