Sanyo Light Generator Dead?

I'm hoping that you guys will be able to help me out. I have a Sanyo generator that goes in front of the rear wheel and it hasn't been used in a few years. I put it on the bike and noticed that it worked great for about 100ft then a high pitched screeching noise almost like a metal on metal grinding started. When that noise came on the light would shut off. Im guessing something in there is sticking but I'm wondering if I can possibly put some grease or some sort of lubrication in there to fix it?

The part in question

Might be easier just to replace it. It's $44 plus S&H from Peter White Cycles http://www.peterwhitecycles.com/sanyo.asp

True, however I hardly ride at night and already have some battery operated lights I carry with me once in awhile. I wasn't sure if this would be bright enough or how I would even like it. Just was gonna give it a try but I guess not anymore.

An Update:

I figured it was probably just in need of some lube so I had some electrical cleaner and lubricant and figured that would be safest to try. So I sprayed some in there and rolled it a bit sprayed some more and then tested it. WORKS LIKE IT IS BRAND NEW!!! So we will see how long that lasts and I hope it is a long time. Thanks for the help and if anyone has similar problems in the future hope this thread will help.

How do you like the dynamo? I haven't really seen any reviews of this dynamo type. I am thinking about getting rid of my battery lights and using one of these.

That sounds very familiar.

Any further update, after the lube job?

I would also like to know how the tuner cleaner worked out for the OP. I've been trying out an NH-T6 I used many years ago. It took about 10 miles for the screeching to start. I lubed with RZ-50 dry lubricant spray and that was good for about 4 miles, though I might not have got much in. Now I'm trying 3-in-1 oil. I didn't have this problem with the generator when I originally used it, so I assume that whatever lubricant was in it 30 years ago is gone now. Probably best to oil these things BEFORE putting them back into service.
