I have been experiencing something strange with the tachometer of my Sunbeam Rapier series IV. Last year the tachometer was professionally rebuilt by a company, the reason for this was both a wavering needle and the change over to a electronically distributor. The tachometer was not installed by myself but by a garage which deals with classic cars.
So far so good and the tachometer is still behaving as it should, but with one exception.....
When I switch on the contact, but without starting the engine the needle of the tachometer goes to about 800/900 RPM and stays there. When I at that point press the button of the horns the needle goes directly up to something like 2500 RPM and stays there while the horns are still activated.
My question is: what is wrong with it?
Thanks in advance for your help!
Regards,
Peter
