Slag, the thing is the spot where the existing rectifier sits is mounted to the battery cage which i believe sits on rubber mounts therefore it isnt grounded correct? I wonder if grounding that cage will have a negative impact?

The external case on the Regulator needs to be grounded; grounding the battery cage will have no effect as the positive terminal is isolated from the cage, and the chassis.  Test the battery cage by mounting it securely, as normal, then use a DVM/Ohmmeter to check for connectivity between the battery cage and the chassis/negative terminal of the battery -- they should be connected, with less than 5 Ohms.

The rubber mounts on the battery cage, are to absorb shock, and vibration.  Shock and vibration will kill a flooded battery.  The rubber helps, but a Gel Cell, or an AGM, are even better -- not susceptible to vibrations, and they are far more tolerant of shocks.  Cheers!

That is such a nice example of that motorcycle I sure would not butcher it up.

The regulator rectifier project is on track. Weather permitting I will put it on tomorrow and see what happens.
I have been keeping notes and if it works out will post the pictures and details. Until then.....

Welp I had to get a few more parts then I wanted for the regulator rectifier build but it's complete and it has solved my charging issue finally. Took her on a 30 Minute run to see how she was going to do and no smoking wires or other issues...yet! Left on a full charge battery and drove her like normal, came back and tested battery at a miniscule loss of power compared to the .1 + volts seen earlier.

Here is the setup, not pretty but I wanted to get the proof-of-concept in the bike and test it after two damn days of fooling around trying to figure out how to mount it.  Heres two images of how I managed to get it mounted. I had to remove the fuse mount and relocate the flasher relay but this is right off of the battery case.



This one shows how it lines up by the battery. This rectifier seems impossible to mount but thanks to its size it actually fits perfectly in the gap.



The current implementation is a little ad-hoc, I need to get a few screws, zip ties, and shorten up some cables. Other than the initial mounting dilemma and my ineptitude with wiring it was pretty easy.

I responded to your other thread, already, but I wanted to make sure you got the information:  your wiring is wrong, and downright dangerous to the bike's existence...  You have un-regulated voltage (15-20 Volts DC, should be <15 VDC) feeding into the whole electrical system!  Be sure to read my posting on the other thread for the details.  Cheers!

Thanks a ton slag, that secondary design i proposed would have been very bad for the bike. I appreciate you saving me from myself. Fortuanatly it seems to be working with design three, thanks to everyones input.
