Commuting to work this morning on my S4R roughly 40 minutes and when I got to the parking garage the bike died. Lights got real dim and them everything went out. Shut the bike off, the tried to turn her back on. No lights, ho gauge sweep, no fuel pump prime, nothing.....Figured it was a bad battery. Tested the Shorai #1 battery and the volts were reading .3. Figured battery was just dead and got a Yuasa brand new and installed.
Yuasa battery got me maybe 5 miles before idle slowly dropped from the steady 1,200RPM to 1,000 then finally died. Pulled out volt meter to take a reading and it was somewhere in the 7v range. Figured now that the battery wasn't being charged by system. Ran back to office and grabbed emergency Shorai battery #2.
Installed Shorai #2 and she fired right up again but immediately the RPMs began to decrease . Used the fast idle to get her consistently at 2K RPM. Rode her almost the whole way home without issue except during the last 2 miles home, the idle dropped quickly and the bike finally died. Tried to restart and nothing again, no gauges, lights, fuel pump prime.
According to other posts, I need a full battery to test whether the bike charging system is functioning properly and the R/R is doing its job. However, given the bike went through 2 batteries on a the way home, can we surmise it's not the battery?
What fuse and I looking to see if it's burnt out, also other than the R/R anything else I need to examine?
Ouch mate. Never a dull moment, eh? I'm guessing either R/R or generator issues. Hopefully it's "only" the rectumfryer.

Can't seem to catch a break. Makes me wish I never parted my S2R.....But gotta get this solved too. The S4 was finally fixed so 1 bike to go [roll]
You will still need to diagnose the problem. Use a conventional battery since the Shorais do not like being run low. This will help you and save me a lot of typing. First visual check should be where the three yellow stator wires connect to the regulator.

Checked the strator wires, no signs of melting and they are connected tightly.

Thanks for filling in the blank :P
Problem turned out to be the Stator. Changed the R/R as well since well.....with my luck.
