Hello All!

I'm new to this forum and to motorcycles -

I just bought a 1980 Honda CB750 F Super Sport. I'm thinking that the alternator is dead. Was running fine for a couple of days until I found a dead battery one morning. I jumped it, and it ran fine for the day. Next day- dead battery.

Thinking the battery was bad, I replaced with a new one. Worked for two days. This morning I was idling in traffic and the engine died. Tried to restart, but could only get a "click" form the the starter. I went home, grabbed the old battery that I had charged back up, swapped back in, and the bike fired right up. I rode it to dinner only to find it dead again when I was leaving. Jumped it and started to ride home- less than a mile down the road the lights dimmed, went completely black and then the engine shut off.

All I can think of is the Alternator is dead and won't charge the battery. I found a new alternator / stator package for ~$200 on eBay.  Is this complicated to install for someone with mid-level mechanical knowledge?

Your help is VERY much appreciated!!!
