Verified compatible with MVH502DSB2 and MVH502DSB reversible plate compactors and the MQ41TDH trash pump.
Key Features
- Exact Electrical Specification: — Matches the coil resistance, contact rating, and switching capacity of the original relay for dependable starting system performance.
- Genuine OEM Sourced: — Manufactured to Multiquip's original design — not a generic substitute — ensuring the relay integrates correctly with the machine's starting circuit.
- Confirmed Fitment: — Directly compatible with MVH502DSB2 and MVH502DSB reversible plate compactors and the MQ41TDH trash pump.
- Protects the Starting Circuit: — A functioning motor start relay properly isolates the start circuit once the engine fires, preventing starter motor damage and protecting downstream electrical components.
- Electrical Safety Compliance: — As a switching component in the ignition and start circuit, using a correctly rated OEM relay is essential to avoid overload conditions, arcing, or erratic starting behavior.
The motor start relay is an electromechanical switch that energizes the starter motor circuit when the operator initiates startup, then disengages once the engine is running. It acts as a buffer between the ignition switch and the high-current starter circuit, protecting low-amperage controls from the heavy electrical load of engine cranking. When this relay fails or degrades, the machine may exhibit no-start conditions, intermittent starting, or a starter that continues to engage after the engine has already fired — all of which can cause rapid wear or damage to the starter and surrounding electrical components.
