Dynastart Diagnosis
Symptoms:
- A fully charged battery is unable to turn the dynastarter.
- The charging light (red on speedometer) is always lit when riding the scooter.
There are at least three causes for these conditions.
- The brushes are stuck, or worn, and need replacement.
- There is a short between the coils and ground. This may occur due to the insulation breaking down due to age.
- One (or more) coils are bad. This situation may occur if you incorrectly connect the regulator wires.
Tools Required:
- 5mm allen wrench.
- Slotted screw driver.
- Dynastart removal tool.
- Tools to remove engine.
- Assortment of metric wrenches.
- Gasket sealant.
