Re: Question About my Generator...

Are you sure there is a problem? If you're measuring 6.2 or 6.3 volts then the charging system may be OK, as that is what the voltage should be when the gennie is charging.

Try switching on and off your headlights (with engine running at more than idle speed - say 1500rpm) while you measure the voltage at the battery. If the system is OK the voltage will stay at around 6.3 (as the regulator cuts in and adjusts the generator output). This'll depend on the adjustment/ settings of the regulator.

If the generator isn't charging you should see a drop in the voltage when lights go on but depending on the condition and capacity of the battery this might only be quite a small change. (There could possibly even be an increase ). If no decrease (or increase) then you'll need to do another check: leave the headlights on for a while (around 10-15 minutes should do, which will lower the voltage / charge on the battery) then start the car, watching to see if the headlights go brighter when you rev the engine. You might notice only a very small change in brightness if your battery is in good condition but any increase in brightness means the generator is working.

Try those tests first and see how it goes. There are more complicated ways to check charging if the above methods don't give a clear indication. Best of luck.
