I got this from my other site:

I know the battery you installed was new and fully charged and the terminals are clean and tight......Right?

I would recommend checking the alternator output.

Check the voltage at the battery with the engine off. Should be around 12.3 volts.

Check the voltage at the battery with the engine at idle (800 - 850 RPM's. Make a mental note of the voltage.

Increase the RPM's to around 1800 - 2000, check the voltage at the battery. Should be around 13.5 - 13.8 volts.

If you have a Comp-U-Fire alternator, the voltage at the higher RPM's will probably be 14 to 14.5 volts.

If you do not have an increase in voltage at the higher RPM's, this would indicate alternator problems. Some possibilities could be brushes sticking in the brush holders, brushes worn out, a bad rotor or a bad voltage regulator.
It's not what you buy, it's what you build.

There is no big single wiring diagram for 1500's like there was for earlier Goldwings- the electrical system is just too large and complex. Instead, the Honda service manual has many pages that show each system and subsystem, and how each system connects to the others.
