To start with I question that 13 volts?? A full charged lead acid battery AT REST AND STABILIZED should be around 12.6 volts NOT 13 which is more what Id expect when the genny is operating. After a longgggggg rest with nothing on check battery voltage again ?? Lets say perhaps that 13 isnt accurate ?? Id see if the voltage rises at fast RPM ?? If the battery and charging system were all good Id expect an accurate reading of at least 13 to 14+ or so subject to battery state and condition and charging system and RPM. An ammeter on the wire from BAT on the VR up to the ammeter is another good indication of actual charging amps, maybe that and another volt meter will show its all okay ???
If a VR's internals or the wire off the VR's FLD post (goes to FLD on Genny) was somehow shorted that can cause overcharging. If after long runs with no lights on the battery outgasses excessive and/or boils out water that's a sign of overcharging
NOTE BOTH the Genny and VR need good grounds, check the VR case/frame to genny connection for good contact.
You may what to check the battery including water levels and if there's a short or a bad cell it can draw excess current. A hydrometer check of each cell is in order including a load test. Look for any one cell that is off colored or milky gray ??
