Instructions for testing, troubleshooting, and modifying the regulator/rectifier on Aprilia motorcycles to fix charging issues and improve battery performance.
This manual provides step-by-step guidance for diagnosing and fixing charging problems on Aprilia RC36, RC46A, and RC46D motorcycles. It covers how to test the regulator using a voltmeter, clean and tighten electrical connections, and modify wiring to improve charging voltage. The document includes real user experiences and modifications, such as adding wires to boost voltage and improving grounding, with voltage readings before and after changes. It also addresses common issues like melted connectors and low charging voltage, with practical fixes and warnings about risks of modification. This manual is written in French.
| Voltage at idle (1200 rpm) before modification | 13.72 V |
|---|---|
| Voltage at idle (1200 rpm) after modification | 14.53 V |
After modification, the voltage at idle (1200 rpm) should be around 14.53 V.
Symptoms include a flat battery, sluggish or inoperative starter, and erratic speedometer readings.
The recommended voltage for charging a sealed battery is around 14.2 volts.
