Do you really need a special rectifier/regulator for Lithium Batteries?

People who would boil batteries on old looms would disconnect it.

The regulator uses the brown sense wire to sense system voltage. When the voltage goes up, the regulator reduces output to the battery, and vice versa. Disconnecting it causes the regulator to stop doing anything and full power is output to the battery. Obviously that will boil the battery.

My regulator/rectifier I got from Rick's has 5 wires: 3 for the stator, 1 red (which I think I should connect straight to the positive terminal from what I've gathered), and 1 black that I think connects to the black/yellow wire that goes up to the headlight/main harness.<snip>

Puke? I'm sure at this point it is more like "YAWN" . I apologize for hijacking your thread, but at times it seems more like debates as to what the proper methodology or procedures to follow, and a discussion between the group. Much like my EX girlfriend over-complicating EVERYTHING simple, then not doing ANYTHING because it's just too damn complicated. :woohoo: LOL

You still haven't installed it yet? I figured you had it running a week ago when you said you already had a SH-775. Steve's drawing is as clear as mud. It really takes some studying to make sense out of it. You just eliminate the brown sense wire. Tape it up, add a accessory, leave it in the plug whatever you want.

It wires in the same as the old one the black / yellow to black = ground, white /red to red = B+ and the 3 yellow wires are stator AC, the connection order does not matter. Feeding through the main fuse going from memory.

To clarify.. All is wired in the same as the original R/R less the brown wire. Since you have the pigtail, I would try to hook it into any OEM plugs to keep it all clean and dependable. Easy peasy.

Grounding the sense wire will boil the battery, I recall that leaving the the sense wire disconnected would result in the RR output being a pre-set level rather than a maximum power. But without a unit to test, or the circuit diagram, I can't verify that.

I was disputing the incorrect assessment that disconnecting the regulator's sense line would stop a battery from boiling. It would make it worse, not better. We are trying to give owners of Kz's good advice. The implied suggestion of disconnecting the sense line will cause damage to the electrical system.

One could connect a diode to the sense wire, but what does the other end of the diode connect to?

NOTE: I have the red wire from the R/R connected to the B+ voltage thru the starter relay which made sense when looking at the wiring diagram and based on some of the responses.

I think it was already well known grounding the sense line on the regulator would boil the battery. That is, as long as it's not connected to the rest of the brown wire circuit. Grounding the brown wire circuit would obviously blow a fuse.

Grounding the sense line or disconnecting it will have the same result... the regulator not seeing battery voltage. That is what is needed: the sense wire having a clean path to the battery. This has been well-documented on Kzrider for many years.
