So i tried that suggestion re changing lower brushes,i loosened the circular tin piece which surrounds the gennie, loosened the gennie hold down strap, disconnected elec. wires and rotated gennie till lower apeture was upermost and bingo !!! then put it back as it was , seems a not bad way to do it ! (thou gennie dashboard lamp still inop!!!)
hey redarmy , tried that , changed all terminal ends on cable ends , done cable continuity tests , voltmeter (aftermarket )shows a charge, mutimeter across batt. terminals shows same , ign "live" no reading from conn. at regulator ,start engine i get reading ! suspect bulb holder perhaps ? it"s became a major pain . Trying to be sensible about this prob, i.e.not lay out for a new regulator a.k.a. >keep replacing parts till i get lucky! any ops. /thoughts by you people on this ,appreciated , ta.
ive had same probs but with the light staying on,changed every thing twice regulater ,dynamo i dont no mate,ask matty on here see what he thinks
thanks anyhow redarmy, will do as u suggest , this prob is taking over my bleedin life ! ... every waking moment........!
The generator may need to be polarized. Connect a wire from DF to earth point. Remove the fan belt. Connect a wire from the battery + terminal to D+ on the generator. The generator shaft should start to spin. Don't run this way for more than a few seconds to avoid overheating. The generator will now be properly polarized. If the generator did not spin during this motoring test, the generator is likely defective. About polarizing Why do generators need to be "polarized". Auto generators need some magnetism to get started. This "residual" magnetism remains in the Field pole pieces even after the engine has stopped. The next time the generator starts up, the residual magnetism creates a small voltage in the Armature windings. Not enough to charge the battery, but enough to allow the Field windings to draw current. As the Field current increases, the pole pieces create even more magnetism. That makes even more voltage in the Armature, and the cycle continues until the generator is capable of producing maximum output. What happens though to a generator which has been stored a long time or is freshly built? The residual magnetism may have decreased to the point where it can no longer get the generator started producing voltage. In the case of a new generator or one which has been mis-treated, the residual may even be of the wrong direction (North and South poles reversed). Polarization is a simple process used to restore the Field pole residual magnetism and ensure the magnetic direction is correct.
crikey , forgot about this, anyhow ,yup, eventually got a bulb holder (new) and yes ! now me lamp workung! >>sometimes it"s the simplist things......
