I have searched and all the threads I have read have different symptoms than mine.

Okay, here's the picture for ya. This bike was completely taken apart by the previous owner (rather carefully I might add), because he wanted to part it out, but I purchased it before he had the chance.
The bike came in several boxes. So, I had to assemble a bike that I never owned up untill now. I had to assemble going off the Honda service manual and many, many pictures from this site. I'm thinking, perhaps I missed a ground wire, or...hell I don't know.

Here's the problem, the bike starts and runs great. I take it around the block, park the bike, and shut it off. The battery is completely drained.

This is my third battery. This current one is brand new. I just had the problem today, so I decided to start a thread here instead of killing another battery.

The first time this happened, I thought it was the stator. So, I replaced it. Happened again, so I thought it was the battery, even though it tested good. Purchased a new battery. Happened again. So, I replaced the R/R to an FH008EE off a '07 Honda 600RR. I bought a new battery too, just so everything was new. Which leads to today. I haven't had a chance to take this bike more than a mile or two from the house. Once I shut it off, it won't start. The starter just BARELY turns the engine over making a very odd noise when I try to start it after taking the bike for a spin.

Now, I can hook up a battery charger and the bike will fire right up. Just will not let me start it after turning the engine off.

My Superhawk's electrical
Battery
Bike off: 12.3 volts
Bike running: 13.7 volts (no change with higher RPMs)

Alternator Charging Coil
0.3 Ohms
No continuity between each wire and ground

I'm pulling my hair out. I just want to ride the damn thing. Since I built the bike, I've never been able to shut the bike off and restart it.

 

I don't know, but can we see the 240Z please? :-)

 

I hope someone knows what might be going on. im having the same problem too but for me it only just started. New battery, new R/R, voltage is about the same and starts fine with a jump and runs good then. then i turn it off and cant start again, it wants to but eventually starts clicking like its dead.

 

I'm just pissed because, it has been doing this since I started the bike for the first time. Spent all this time and money to only end up with the same issue again and again.
I'm going to check the entire wire harness from front to back. When I installed the harness, I cleaned each ground and put diaelectric grease on as well.

VtrInMtl, as soon as I can figure out how to post pictures using a iPad or a smart phone (Samsung Galaxy S III), then I'll post some pictures of the GNZ for ya.

 

A buddy of mine just reminded me of a problem we had with a '90's Chevy Cavalier some years back. It was having the same issue, but the starter was causing the problem. Changed the starter and the car ran just fine. I'm going to look into that as well. Maybe heat soak is doing something to the starter. Hmm...

I wanted to pull the starter off to clean and paint it anyways. The engine looks great, but the starter is all rusty and nasty.

 

Took the starter off and pulled it apart. It was kinda crusty with that white powdery corosion and a little rust on the case, but the insides looked really good. Everything tested good and the parts were in spec.
I cleaned it up and got a coat of paint on it tonight. Tomorrow after work, I'll put 'er together and pop it back in and see what happens.

 

Make sure the starter motor connection is clean and free of corrosion where it bolts on under the rubber hood. Same for the cable back to the starter relay nr the battery.

 

Get hold of the wiring diagram and a DC ammeter, disconnect the battery positive cable and connect the meter between the battery + terminal and the cable you just disconnected. Now see if the meter shows any current flowing, if yes remove the fuses one by one until the reading drops to zero (hopefully if there is a problem it's only on one fuse!) If you pull a fuse and current drops to zero, replace all the other fuses just to make sure there is not more than one fault. Now replace the fuse on the suspect circuit and identify the components on that circuit and if possible unplug or disconnect them one by one again checking the current on the meter. If or when it drops to zero, note which is the offending plug etc. and reconnect all the others checking the meter still shows zero current. Once you have narrowed it down to a small area you can start working through that looking for pinched wiring or signs of corrosion on electrical fittings. Good luck and let us know how you go :-)

 

After reassembling the freshly painted and fantastic looking starter, I installed it back on the bike and she fired right up. However, after the battery was drained yesterday, I never charged it back up. So, I have a couple ideas what's going on here.
It was to late tonight to take 'er around the block, so I'll do it tomorrow morning and report back.

If it drains the battery again after taking it for a quick spin, I'll have to use your advice s4steve.

 

If the starter motor cable connection is corroded then a marginal battery will struggle to turn it over but it is extremely unlikely that your battery will be constantly draining via the s.motor. For that to happen the starter relay contact will have to be supplying power to the s.motor permanently. I suppose you could check the s.motor only turns when you press the starter button. Is all the wiring standard or has it been modified?

 

The wire harness is completely stock, except for the newly added R/R, which I hardwired to the harness. This problem existed before and after I soldered the R/R in. Like I mentioned earlier, when I installed the harness, I used dielectric grease on each ground. I used emery cloth to clean the connector on the end of the wire as well. I may have missed a plug or two with dielectric grease, however when I built the bike, I do remember hooking everything up and every connector on the harness looked very good. Nothing to raise an eyebrow over.l
I wish could post pictures, because I could show how clean everything is.

If it's not the starter, then I'm assuming there is a loose connection somewhere inside the harness hidden hidden by electrical tape.

The only corrosion I found on the entire bike, was on the outside of the case of the starter. Maybe that little bit of corrosion was enough to cause resistance between the starter and the engine, since that's where it's grounded? Just thinking out loud.

When it comes to electrical, I'm definetly not a newbie, but I'm not quite a profesional. For instance, the R/R, each wire was cut at a slightly different length, so you don't have a big ball of soldered connections underneath electrical tape. Each wire was tined before being soldered together, shrink wrapped, and then electrical taped.

 

I figured out how to post pictures!

Here is the R/R and a couple of the starter.





And for the dude who wanted to see the GNZ. In these pictures, the car is far from finished, but you get the idea of what it is.

 

thats so sexy

 

I had this same thing happen on my 2003 VTR. After changing several batteries out and chasing wires I got sick of it and changed the voltage regulator which is located on the right side of the sub frame in the tail (pictured in your earlier posts). Changed it and have never had another problem since...
