I am new here and I thought I would contribute. I found a few websites for downloading Repair Manuals and some of them have other types of manuals(electrical set-ups etc). The Free ones take longer to download, but I am in no rush. Hopefully, this will be helpful to someone.
Free Motorcycle Repair Manuals - (a bit of a pain in the ass, it directs to other websites that have free manuals, download speeds are slow, but I managed to get what I wanted). Free is Free, even if it did take time. They have over 400 Manuals for about 10 makes.
RepairManualClub Download Area - Went through a process for about 10 minutes and then realized I needed to pay per download. It's is only 5 bucks a download, but 5 bucks is 5 bucks. Still, nice site, easy to use.
http://www.themotorbookstore.com/motorcycle-manuals.html - This is not for Instant Download, but they have a huge range of manuals. A but pricey, especially when you consider the Post and Packing.
And of course there is ebay. This is where I bought my last manual. Usually get one for 5-10 bucks
