Recommended R/R?

[BassCliff]

All of the wires that were melted were at the spade connectors the p.o. put in. All of the other wires look fine. Im fighting the urge to connect the new one and fire the bike up!!! Im hoping that the connectors were the culprits and thats all its gonna be......hoping! Also ran a wire long enough to ground directly to the battery. My only question is, what do I do with the original ground wire in the wire harness?

Hi,

Wait a minute. I'm confused. What ground? Normally the stock r/r unit will ground to the battery box. That is the ground that should be moved to the negative terminal of the battery.

If you already have a non-stock r/r unit on your bike then it could be a 6 wire unit with a black "sense" wire and a green ground wire. How many wires does your current r/r unit have?

And wasn't this the one that melted its resin because it got so hot? I would not keep that unit if I were you. Install the new one. Have you tested your stator? What is the AC output voltage of the three legs? What are the resistance readings between the legs and from each leg to frame ground?

Thank you for your indulgence,

BassCliff

its a five wire. Three yellow, a red and a black with a white stripe. I looked at the schematic Billy Ricks posted but my wires arent the same colors. I wired the yellows together, the red together, and the black I was gonna run to the battery as I though it was the ground. Is this wrong?

That's fine but you want make sure you have a ground from the battery to the engine. It's also a good idea to run a ground from one of the r/r mounting bolts to the frame.

This is Jim's, posplayr, diagram.

Ok yea I got it. The black w/white stripe runs to the battery, all I did was run a new wire instead. Everything is hooked up, just gotta wait for the new Fluke to get here.

Its a whole new R/R that I have wired in. The ground wire from the previous R/R was already grounded to the negative battery terminal. As suggested, Ill run another ground from the R/R mounting bolt to the frame too. I havent tested anything yet as my Fluke decided to stop working and I had to order another. I should be ready to test no later then Wednesday. Thanks for the help!

The frame should be the central ground point, not the RR mounting bolt. This arrangement would invite ground loops and besides, it's hard to implement.

So where am I supposed to ground? The battery? The frame? I have it ground to the negative battery post right now.

Make sure there is a second ground going from the bettery to the back of the engine in the transmission area. It fits right between the swingarm and the back of the engine. It's also a good idea to run a ground from one of the r/r mounting bolts to the frame.

It's not meant to be an actual ground, it's so the r/r can shunt to something other than itself.

Here's Jim's thread on grounds.

He suggests that the r/r ground actually be attached to one of the r/r mounting bolts so you have a single point for all grounds. Then run the other grounds from there.

We had a contest a while back; the price was an Duanage Honda R/R. The question was were does all the charging current in the system return to? The answer was the R/R(-); that is why the single point ground is at the R/R mounting bolt.


Not to the frame, not to the battery, electricty moves in "circuits", so the current that comes out of the R/R (+) has to return to the R/R (-). No where else.

The simplified schematic you saw provided the analysis to select the best grounding point specifically to eliminate any ground loops. If you study it you should be able to tell.

RustyBronco won. Baltzor came in a close second. Even though he came in after Rusty's answer, Baltzor's answer was technically superior but beyond the scope of the contest.

There is a ground running from the battery to the back of the tranny. Should there also be one to the chassis?

It wouldn't be a bad idea. With the motor mounts being painted you may not get a good ground to the frame just through them.

Billy,
I just posted a couple drawing showing the difference between how the current flows depending on how the grounds are constructed.

This may be close to a wash if all contacts between the battery(-) and R/R(-) are kept clean but as we have come to expect things fall into dis repair. Putting a bigger wire between the battery and R/R doesn't really help the situation when it is connections and crimps that get dirty.
