The saga of the 650 Custom thus far

[oughtsix]

Hello all around, I'm new here.

I guess we'll start this from the top. Last year my buddy alec was looking for a bike, and I happened to see a CX650C in a driveway with a sign on it. So I stopped and asked, and the owner only wanted 800 for it. The thing was that he said it needed a stator, but he had just been hooking it up to a trickle charger every night after he got home from work as that's all he used it for was to an from work. So i tell alec and he figures he wont mind charging it up. So he buys it, and rides it for a year or so. He works at the ford dealership while he goes to vo tech getting his ase certification and all that. Anyway, the shop manager over there gets to talking to him one day about the bike and tells him that he thinks that the problem is not the stator (thank god...) but rather a bad voltage regulator.

That brings us to last week. I was wondering what I was going to do with my four wheelers left in the back yard, a 02 recon and a 92 Timberwolf. Only the recon ran. So I called alec and wouldnt you know he was tired of messing with the bike. So a trade was arranged.

So i get the bike home and repaired the fuel petcock which was stopped up and get the gas tank cleaned out while I'm at it. Also fixed a small oil leak and other minor stuff. I go to riding it around and such and decide to do my own diagnostics on the VRR. So put the volt meter on the battery and rev to 5k, as per the clymer manual. 12.5 volts. Okay. Probably not the stator (See, you can run the bike as long and as far as you want to, as long as the engine doesn't stop. I logged 70 miles on it yesterday. Battery was as dead as it could be when I stopped it back at the house.)

Next I run the resistance test as per the clymer manual. It checks out.

Hmm.

So I unplug the output side of the VRR and put the meter on it. Rev to 5K. 15.5 volts or so. Wow. Okay.

Now. questions:

Is there some reason that 15 volts would not charge the battery? Perhaps it's too high, or maybe the rectifier is faulty and the current is not phased right to charge? (I'm no electrical engineer)

Or is this more likely a ground/blown fuse situation?

Thanks and sorry for the length. just wanted to fill the details in ahead of time.

Meanwhile, I'm going to go check some grounds and flush the radiator.

Peace

Brian

If it`s putting out 15v at the VRR plug & at the battery it`s only getting 12.5 then you have a wire problem. If it`s 15 at the plug then the batt should be getting that too.
