A funny thing happened to me driving my Tiger home from British Car day a
the Boston Museum of Transportation. About 70 miles into my 130 mile trip
home I noticed a humming sound that increased with engine RPM. The noise
seemed to get worse the further I drove. When I arrived home I determined
that the noise was comming from my generator. I decided to investigate the
problem further the next day after everyting had cooled off. The generator
made the same noise even when cold. I also noticed a waxy yellow substance
deposited in a line on the hood and engine compartment adjacent to the
generator fan. I cleaned the substance off with solvent, but found that
the paint had actually been stained. Polishing compound still hasn't
removed all the stain.
Anyone have any ideas what is happening? The generator has new field coils.
