When I bid on my MEP-804b last September I failed to see that it didn't have an alternator on it. Of course I had to find one when I brought the unit home. I found a new one on eBay. It wasn't too awfully expensive but it arrived damaged. I contacted the seller and they sent me another one no problem. They told me to keep the old one. I've been hanging on to it for? If you would like it, it's yours. You should be able to transfer any of the parts over and make a good one with your case.
