Alternator 102646GT – Optimized Product Page Content

🔹 Product Overview
The Replacement Alternator with Genie Part Numbers 102646 and 102646GT is a heavy-duty electrical component essential for maintaining the charging system on various Genie Boom Lifts (S-Series) and Telehandlers (GTH-Series). This alternator is specifically matched for the diesel engines used in high-demand models like the S-105 Boom Lift and the GTH-844 / GTH-1056 Telehandlers.
The alternator’s primary role is to convert mechanical energy from the running engine into electrical energy (DC power) to recharge the machine’s battery and power all electrical systems while the engine is running (e.g., control modules, solenoids, lights).
A faulty alternator will lead to the battery constantly draining, causing the machine to eventually fail to start or experience intermittent electrical system failures. Replacing the old unit with the 102646GT alternator ensures the charging system is operating at full capacity, maximizing battery life and ensuring electrical reliability.
🔹 Key Features & Benefits
- ✅ Charging System Power: Essential electrical component for converting engine rotation into usable DC power for the battery and electrical components.
