Problem 1: flat battery. Not unexpected but after it refused to recharge I got a new one from Halfords (dreadful service by the way).
Started first time but Problem 2 revealed itself - the main beam wouldn’t turn off.
Suspecting a broken or missing spring I dismantled the switch to find that the switch relies on the weight of the lever to hold the switch open but the 42 year old nylon plunger is gummed up and not sliding cleanly - a quick clean sorts that out but then Problem 3 arrives when I notice that the brass rivet holding the contact in place and doubling as a plug for the feed wire is loose.
Problem 3a: its not loose anymore, it’s broken off completely.
Problem 4: part no. AAU7994 is obsolete and ‘hasn’t been available for years’.
Solution 1: AAU7996 can be modified with the baseplate from my switch, so that’s been ordered today.
To be continued.........
