The Honda 38450-763-D03 Combination Relay Assembly is a genuine OEM part designed for H3011 and H3013 riding mowers. As a direct Honda OEM component, this assembly is sourced and manufactured to the same specifications as the original unit installed at the factory. This part fits H3011 and H3013 riding mowers — confirm your serial number against the fitment table before ordering, as Honda supersedes parts at serial breaks and the correct assembly can vary within the same model line.
Key Features
- Genuine Honda OEM — sourced directly from Honda, ensuring the relay assembly meets the same electrical specifications as the original component in your riding mower.
- Correct Switching Function — a Combination Relay Assembly consolidates multiple relay functions into one unit, so correct specification is essential for reliable circuit operation across the mower's electrical system.
- Model-Specific Fit — designed for H3011 and H3013 riding mowers; verify your serial number against the fitment table to confirm this is the right assembly for your machine.
- Restores Electrical Operation — a failed or degraded relay assembly can cause intermittent starts, inoperative safety circuits, or complete electrical failure; replacing with this genuine part restores normal function.
A combination relay assembly serves as a centralized switching hub within the riding mower's electrical system, controlling current flow to multiple circuits through a single integrated unit. Rather than relying on several discrete relays, the combination design consolidates those switching functions, which simplifies the circuit layout and reduces potential failure points. When the relay assembly fails, affected circuits may become unresponsive or erratic — symptoms that can include a mower that won't start, safety interlocks that stop functioning, or electrical accessories that cut out unexpectedly — making prompt replacement with part number 38450-763-D03 the straightforward path to restoring full electrical function.
