The charging system keeps the battery charged while riding. If the battery dies quickly, the charging system may be faulty. Check the voltage regulator and stator. Use a multimeter to test them.
Follow these steps to test the charging system:
- Start the engine.
- Set the multimeter to DC voltage.
- Connect the multimeter to the battery terminals.
- Check the reading. It should be between 13.5 and 14.5 volts.
- If the reading is low, inspect the voltage regulator and stator.
Here is a table to summarize the testing steps:
| Step | Action |
|---|---|
| 1 | Start the engine |
| 2 | Set multimeter to DC voltage |
| 3 | Connect multimeter to battery terminals |
| 4 | Check the voltage reading |
| 5 | Inspect voltage regulator and stator if reading is low |
Battery Replacement
If the battery won’t hold a charge, it may need replacing. Here’s how to replace the battery in your Tomos Classic:
- Turn off the moped.
- Locate the battery compartment.
- Disconnect the negative (-) terminal first.
- Disconnect the positive (+) terminal next.
- Remove the old battery.
- Place the new battery in the compartment.
