The Multiquip EE61320 Jumper Relay Diode DEF Control is a genuine OEM component designed for MQ Power Fuel and DEF Tank units, including the DEFTANK1, DEFTANK2, and DEFTANK302. As an authorized Multiquip OEM part, EE61320 delivers the correct electrical specifications required for proper DEF system operation — no guesswork on compatibility. This part is sourced directly from Multiquip, ensuring it meets the same standards as the original component installed at the factory. If your DEF control circuit is showing faults or relay issues, replacing it with the correct EE61320 restores normal system function.
Key Features
- Correct Diode Rating for DEF Circuit Protection — Engineered to the exact electrical specification needed to protect the DEF control relay circuit from voltage spikes and reverse current.
- Genuine OEM Component — Sourced directly from Multiquip, this is the same part used in original production builds of the DEFTANK series.
- Confirmed Fitment — Verified for use with DEFTANK1, DEFTANK2, and DEFTANK302 MQ Power Fuel and DEF Tank units.
- Drop-In Electrical Replacement — Matches the original connector and jumper configuration, allowing straightforward installation into the existing DEF control harness.
- Fuel System Electrical Integrity — A functioning relay diode prevents erratic DEF dosing signals and control board faults that can disrupt compliant emissions operation.
- Critical Emissions System Component — Proper operation of this relay is essential for maintaining accurate DEF delivery and avoiding fault codes that can affect equipment compliance and performance.
The Jumper Relay Diode DEF Control serves as a protective and switching element within the DEF (Diesel Exhaust Fluid) control circuit on MQ Power fuel and DEF tank systems. It prevents reverse current from damaging the control board and ensures clean relay switching so DEF dosing commands are executed accurately. When this component fails, the system may generate electrical faults, deliver incorrect DEF quantities, or disable the DEF system entirely — all of which can impact emissions compliance and machine operation.
