I thought it would be pretty straight forward :x

This is all the wiring diagram I have for the ebay purchased rectifier/regulator. How would you connect to it? What should I expect?

Link to the RR i got...
https://www.ebay.com/itm/202138206907" onclick="window.open(this.href);return false;

Here is a pic of the bike on it's first ride since I bought it stripped down to the crank. Still a working progress.
As you'll notice I have a lot of extra parts!

That looks to be similar to the Tympanium rectifier/regulator that I use.

The GT500 has 3 alternator output wires. Wire them up as shown here: http://www.suzuki2strokes.com/forum/viewtopic.php?f=2&t=4858&start=17

Y/G wires goes to one of the R/R yellow wires. It doesn’t matter which one.
R/G & G/W wires goes to the other R/R yellow wire.
The black wire is the ground.
The red wire is the battery + wire.

I got them wired as the link shows.

But I am still having issues. :x

if I run the headlight it kills the battery. like it did tonight!

i checked the R/R out put to battery, and I got -3.5v (negitive) red to red, black to black

So I switched red to black, black to red, and got +6.0v

Is there a detailed wiring schematic for the lighting coils. I am wondering if I mixed the wires when installing the 2 new coils last winter. And/or got the A coil mixed up with the B?

This is driving me to drink!!!

It doesn’t matter if you switch coils A & B.

Each coil has 2 wires for a total of 4 wires. Those 4 wires connect up to 3 wires (Y/G, R/G & G/W). Its possible to get this wrong & end up with the two coils working against each other. I’ll check to see how mine is wired up in the next few days.

Sorry for the delay.

My charge coils have brown & black wires. The two brown wires connect to Y/G.
Yours is wired up the same. But its possible to install them upside down. Post a link to a pic of your setup
