I have a honda ex1000 generator. The owners manual gives specs of 120vac at 3600rpm. Also 12 volt dc to charge a battery. It starts and runs great but measures 240 vac at both receptacles. There is no regulator on the unit. Is this wired for use in Europe or Australia?

at the lower part of the wiring diag you see the stator housing ther is a set of Diodes these need to be checkedthey will need to be removed and tested to test use a ohm meter and set to the Diode setting or the 200 to 2000 ohm's settings the diode will have a stripe this is the cathode side to test place one lead on each end it won't matter you should read any reading when you reverse the leads you should not get a reading if you get a reading bolth ways replace them same if you dont get any readings as to the rectifier yes this will cause i issue as to testing you need to have the specks for the diode it is nothing more that 4 Diodes in a package but you need to know witch points are the annode and cathode it is better just to replace ther only around $5.00 and under i hope this helps. please repost your findings at the lower part of the wiring diag you see the stator housing ther is a set of Diodes these need to be checkedthey will need to be removed and tested to test use a ohm meter and set to the Diode setting or the 200 to 2000 ohm's settings the diode will have a stripe this is the cathode side to test place one lead on each end it won't matter you should read any reading when you reverse the leads you should not get a reading if you get a reading bolth ways replace them same if you dont get any readings as to the rectifier yes this will cause i issue as to testing you need to have the specks for the diode it is nothing more that 4 Diodes in a package but you need to know witch points are the annode and cathode it is better just to replace ther only around $5.00 and under i hope this helps. please repost your findings
