Issue with ac-dc converting.. Please help pic inside

[Jimmy]

Is this the right way to do it?
Would love some help.

You can't have both AC and DC side grounded to the frame.
One or the other should not be grounded to the frame, "floated".

I think I am floating DC. So every ground needs to be run back to the battery negative terminal.

EDIT: Actually, I took a closer look and it does look this is what you have drawn. Sorry!

this video series is from my conversion on an 07, not sure how the 12 is wired though. Here is part one:

Your diagram looks fine to me.

The wiring schematics are in the manuals here.

My issue is that when im running my bike without using my led, its charging around 16-17v!?
But as soon as i turn it on, the V is dropping fast from the battery.

So i have to open up my stator och do the floating ground thing you talked about?

There is no value to floating the stator on a standard kickstart bike.

A grounded stator and an isolated rectifier will do what you need. You feed the rectifier with the white wire and ground. The DC output connects only to the battery and your lights.

If the voltage seems a bit high, try using the yellow wire to power your rectifier (leave the white wire disconnected). You should confirm the actual current draw of your LED light. Use an amp meter and a car battery to find out the draw. Assume 2K3 at 70W/14V=5amps at high RPM, so stay below 4amps on your lighting.

A voltage drop under load is normal. As long as you can maintain 13VDC at the battery (under load) you should be OK.

Yea, but a 40w led should not be more then 5amp right? Might be that the lamp is pullibg to much then cause my volt is dropping fast on the battery even on pretty high rpm. I need a new light i assume then... my battery dropping fast dom to 8-9v

When you say feed the r/r with white cabel and ground.. should i take that ground from frame or the - on the battery?

Input to the voltage rectifier is stator white plus frame/chassis ground (or can be stator yellow plus frame/chassis ground at slightly less voltage). Do not ground the battery minus!

If you get a lot of voltage drop, either your lights draw too much current OR you have a bad connection somewhere. A bad connection will reduce current flow but still can measure OK for voltage. A really bad connection will drop voltage. Bad connections can be wires OR ground points. You need to go through everything carefully, even the quality of your switch contacts is important.

Have you checked to make sure the stator connections are not corroded?
