Hello! Let me get the details out of the way:
2006, No electrical mods aside from a USB charge port powered by the tag light. Has a charging issue as of 3 days ago. I have researched on possibilities and gathered all test info to perform including the service manual procedures.
Have followed all advice from searching so far and others results with same issue but no luck as of yet
Issue:
The bike lasts as long as the battery's charge while running. While off it sits fine as long as the battery wasn't weak upon shutting it off.
Tests/results so far:
-12.4v across the battery terminals. Voltage drops down with ignition or high beam on (11.7ish). Does not rise at all with Engine revved to 5k.
-Stator tests in the manual followed with the exception of the AC voltage (Turns out 3grand in a nice snap-on meter still isn't enough for it to test normal AC voltage unless I'm stupid and not seeing it). Meter appears to go up to 50v AC only, which the rev tests on the yellows easily reached that peak at about 2k rpm, can only assume the 65ish acceptable voltage would easily be hit if it could read it.
-3 Yellow wires from stator read an acceptable .26 ohms across them every possible combination.
-All harnesses and plugs are in pristine condition. No darkened areas to hint to heat, no melted plugs or wires, no pins dislodging from the connectors. All connectors tight and clear from pinched/rubbing/raw areas or breaks.
-Removed stator cover/stator for physical inspection hoping to find burnt coils like a lot of other folks... nothing. Looked fine with only maybe a slight difference in color on the barely orangeish side)
-As for the rectifier/regulator..... this is where My first question comes into play. The Service manual shows what the reading should be between the different wires when using a 2v Diode check setting on a multimeter. I've measured from the 3 black input wires to the output Black/Red wire with all readings acceptable by the manual, same with the Black/White to Black/Red readings. (.53 between Blacks and Output, .78 between B/W and B/R)
It also has readings you should receive when reversing the probes on the same terminals .... I'm lost. These are diodes which keep the voltage/current traveling in one direction right? Wouldn't a reading of voltage flowing the other way show the Diode was bad? I did not get a reading at all with the probes reversed.
-Battery was fully charged, Load tested by a local Bike shop earlier today to rule it out. Tested great according to them.
Soooo... Not sure where to go next without just throwing parts at it. I don't have the money for more than one of these 3 parts (have to borrow a little if it turns out to be a stator) so have to be SURE it's the proper part. Anything else I'm missing? Another part that could cause this or a test I've looked over? This is my main transportation or I wouldn't be in such a rush to figure it out.
Thanks for reading and any advice in advance.
