blowing head light bulbs and tail and park

Possible causes for headlight, tail light, and parking light bulbs blowing on a CPI ARAGON include:

1. Overvoltage from the charging system – The correct battery charging voltage is 13.5 ± 0.5 V. If the voltage exceeds this range, it can damage bulbs.
2. Faulty voltage regulator – May allow excessive voltage to reach the bulbs.
3. Incorrect bulb wattage – Using bulbs with incorrect specifications can cause overheating and failure. The correct values are:
- Low beam: 55 W H1
- High beam: 55 W H1
- Position lamp: 5 W
- Rear/stop lamp: 21/5 W
4. Wiring issues – Short circuits or poor ground connections can lead to sudden voltage spikes.
5. Vibration or loose fittings – Can cause filament damage in bulbs.

Regular checks of the charging voltage and electrical connections can help prevent bulb failures.

REASSEMBLY If reassembling engine parts, precisely obey the instructions regarding defaults of tightening torques and other settings. The following parts always have to be replaced prior to reassembly.
  • Page 11 GENERAL INFORMATION GI-7 MAINTAINING THE ELECTRICAL SYSTEM 1. Prior to maintaining the electrical system, the ignition has to be switched off and the battery ground cable has to be disconnected. 2. To avoid slack, wiring harnesses have to be fixed with cable clamps or cable fastening ribbons.
  • Page 12 GENERAL INFORMATION GI-8 5. Do not drop relays, sensors, or other electric components and do not expose them to vibration. 6. Electric component parts built in the microcomputer or relay are sensitive to heat and can easily get damaged. If for maintenace works the temperature must be risen above 80 °C, those electric component parts have to be removed prior to maintenance.
