Why Replace Your VW Thing Generator?

Original generators in air-cooled VWs like the Thing often fail due to age, worn brushes, bearings, or voltage regulator issues. Symptoms include dim headlights, slow cranking, a glowing generator warning light, or complete loss of charging. A failing unit can leave you stranded and damage your battery.

This new 12-volt generator delivers:

• Consistent Charging: Maintains proper voltage across RPM ranges for reliable battery charging, even during low-speed driving or idling common in classic VWs.
• Bright Lights & Accessories: Supports headlights, taillights, wipers, horn, and basic electronics without voltage drop.
• Durability: Built to withstand the heat and vibration of air-cooled engines.
• Direct Bolt-On: No modifications needed saves time and money compared to conversions.
