Suitable for Vespa Rally 200 with Femsatronic ignition system.
This component looks like a classic capacitor, but in the Femsatronic of the Rally 200 it is a resistor with 250 Ohm. It is an important component of the early contactless Vespa ignition and directly influences the starting behavior and engine function in the lower speed range.
The resistor is part of the Femsatronic ignition of the Rally 200 and is electrically integrated into the system. If it fails or its value is significantly outside the target range, this is often immediately apparent in the driving behavior.
| Blue | Resistance = 250 Ohm |
|---|---|
| green | Pickup = 280 Ohm |
| red | Excitation voltage / charging coil = 170 Ohm |
Measure all values against ground without the ignition box (CDI) connected.
The distance between pickup and cam should be between 0.25 mm and 0.30 mm on the Femsatronic Rally 200. Even if the resistor is intact, an incorrect distance will result in unreliable ignition triggering and poor engine function.

| Resistance value | 250 Ohm |
| Optics | Design similar to capacitor |
The CEAB resistor is a small but ignition-relevant component of the Rally 200 Femsatronic. If the engine starts poorly, runs weakly at the bottom or stalls when accelerating, this resistor, together with the pickup distance and measured values, is one of the first points to check.
