Re: battery, stator or regulator?
I had a voltage drop that ended up being the voltage regulator/rectifier.
How did you check the voltage? Check it at the battery +/- terminals using a volt meter. Do this test with the high beam headlight on. Rev the engine up to 5,000rpm and you should ( if all is well ) get 15.5 Volts. ( Honda spec/test method )
You're problem may be due to corrosion at a connector or where you soldered the wires together. Also consider with a missing connector water can easily get in there and cause a short circuit.
To test the stator as per Honda specs:
Remove the three prong white connector. Check for continuity between each yellow wire and ground. there should be no continuity, if so replace the stator. Now check the resistance between all three yellow terminals coming out of the stator. Honda spec is 0.1 - 1.0 Ohms. If it is much out of this spec replace the stator.
To check the regulator/rectifier:
Unlplug the connector and check for tight fitment, not loose. Check for any signs of corrosion. I use battery terminal cleaner to remove corrosion, but let it all dry before plugging back together. Also dielectric grease comes in handy to prevent corrosion.
On the WIRE HARNESS SIDE check voltage between the red/wht & ground wire ( green ), battery voltage should be present. Also on the wire harness side check resistance ( ohms ) between each yellow and yellow, should be 0.1 - 1.0 ohms. Check resistance between green wire and ground, there should be continuity.
Check your ground wires and make sure they are not corroded. Check the R/R to make sure it is good and tight against the subframe and not loose.
Info is all from the manual.
