Multiquip 42602-62 Alternator 14V 110A

The Multiquip 42602-62 is a genuine OEM Alternator 14V 110A designed for STX6H and HTX6H Whiteman ride-on power trowels. As a direct OEM replacement, part 42602-62 is built to the exact electrical output specifications of the original component, ensuring correct charging system performance with no guesswork on compatibility. This alternator is confirmed to fit the STX6H and HTX6H series, making it the straightforward choice when replacing a failed or underperforming charging unit on these machines.

Key Features

• Correct Output Rating: — Rated at 14V and 110A to match the original charging system demand of the STX6H and HTX6H, preventing undercharging or electrical overload.
• Genuine OEM Component: — Sourced directly from Multiquip, this alternator meets the same electrical tolerances and connector specifications as the part it replaces.
• Direct Drop-In Fit: — Engineered to mount and connect exactly as the original, using the existing bracket points and wiring harness connections on STX6H and HTX6H trowels.
• Sustained Electrical Supply: — A properly functioning alternator keeps the battery charged and powers onboard controls during operation; a failing unit can cause erratic behavior in the hydraulic control system and unexpected shutdowns mid-pour.
• Electrical System Safety: — Installing an alternator with the correct voltage and amperage output protects sensitive control electronics on these hydrostatic trowels from voltage irregularities that can cause component damage.

The alternator is responsible for generating electrical power while the engine is running, keeping the battery charged and supplying current to all onboard electrical systems. On hydrostatic ride-on trowels like the STX6H and HTX6H, a healthy alternator is critical to maintaining consistent operation of the engine controls, instrumentation, and any electronic safety systems. When an alternator begins to fail, symptoms typically include a draining battery, warning lights, and eventually a machine that will not start or shuts down unexpectedly during use.
