Vespa LX 50 Electrical system Ignition circuit 1) Check the state of the spark plug (clean it with a metallic brush, remove all incrustations, blow it with compressed air, and replace it if necessary). 2) Without removing the stator, perform the checks described below: After a visual inspection of the electrical connections, carry out the measurements on the charging coil and pick-up (see table), and check for continuity using the special tester, 020331Y.
Electrical system 6) Failure of the oil and petrol check lamp. Operations FAULT 1: Make sure that at 5000 rpm with the lights on that the regulation voltage is between 13V and 14.5V. Make sure that at 5000 rpm with the lights off the regulation voltage is ï£ 16V. If the regulation voltage is greater than >16V replace the regulator.
Vespa LX 50 Electrical system FAULT 4 a) By positioning tester 020331Y between the yellow wire terminal (8) on the regulator and the black wire (6) (FIG. D), check the generator output voltage is within 26 and 30 V at 3,000 rpm (this measurement must be carried out with the battery detached). In the event of anomalies, replace the stator; otherwise proceed to point b). b) Yellow wire (1) attached to the regulator.
Electrical system Vespa LX 50 (FIG. G) If the above tests have positive results, jump the contacts 5 (yellow/red) and 7 (blue/black) on the connector, set the key switch to ON and shift the turn indicator switch to the right and left to see when the lights are steadily on (as they are powered directly from the battery). If even after this operation the turn indicators fail to turn on, check that the wiring is not damaged and the switch works properly.
Vespa LX 50 Electrical system Maximum 24 h 3) Constant current battery charge mode -Charge current equal to 1/10 of the nominal capacity of the battery -Duration of the charge: 5 h WARNING -WHEN THE BATTERY IS REALLY FLAT (WELL BELOW 12.6V) IT MIGHT BE THAT 5 HOURS OF RECHARGING ARE NOT ENOUGH TO ACHIEVE OPTIMAL PERFORMANCE. IN THESE CONDITIONS IT IS HOWEVER ESSENTIAL NOT TO EXCEED EIGHT HOURS OF CONTINUOUS RECHARGING SO AS NOT TO DAMAGE THE BATTERY ITSELF.
Electrical system A density reading of less than 20° Bé indicates that the battery is completely flat and it must therefore be recharged. After charging the battery, check each element electrolyte level and density. If the scooter is not used for a given time (1 month or more) it will be necessary to periodically recharge the battery. The battery runs down completely in the course of three months.
Vespa LX 50 Electrical system Specific tooling 020333Y Single battery charger 020334Y Multiple battery charger 1)- Remove the short closed tube and the caps, then pour sulphuric acid into the cells using the type specified for batteries, with a specific gravity of 1.26, corresponding to 30° Bé, at a minimum temperature of 15°C until the upper level is reached. 2) - Leave to rest for at least 2 hours; then, restore the level with sulphuric acid.
