The Multiquip 51511 is a genuine OEM Negative Battery Cable (512 mm/1.67 ft.) designed for select Multiquip concrete pumps and rollers including the LS300GK, LS300G, LS300P, AR13D, AR14H, and MRH800GS. As a factory-sourced component, part 51511 is built to the same specification as the original cable installed at the time of manufacture, ensuring a direct, correct-length connection in the electrical system. This cable measures 512 mm (1.67 ft.), matching the routed path in compatible machines without trimming or splicing. Keep a genuine replacement on hand and avoid the compromises that come with incorrect cable lengths or undersized conductors.
Key Features
- Factory-Correct Conductor Sizing — Built to OEM specification with the correct gauge to handle the rated current draw of the machine's electrical system without heat buildup or voltage drop.
- Exact 512 mm (1.67 ft.) Length — Pre-cut to the original routed cable length, so it installs directly into LS300GK, LS300G, LS300P, AR13D, AR14H, and MRH800GS without modifications.
- Genuine OEM Part — Sourced directly from Multiquip, part number 51511 matches the original component in material, termination style, and insulation rating.
- Secure Ground Path — A properly functioning negative cable maintains a clean, low-resistance ground return, which is critical for reliable engine starting and stable operation of electrical components.
- Electrical Safety — A correctly sized and terminated negative cable reduces the risk of arcing, voltage irregularities, and electrical faults that can damage control systems or create hazardous conditions.
The negative battery cable forms the ground return path in the machine's 12-volt electrical circuit, connecting the battery's negative terminal to the machine's chassis or engine block. This ground connection is essential for every electrical function on the equipment — from engine cranking to control panel operation. When a negative cable corrodes, develops a poor terminal connection, or fails entirely, the result can range from difficult starting and erratic instrument behavior to complete electrical failure. Replacing a worn or damaged cable with a correctly sized OEM cable restores a clean, reliable ground and protects the rest of the electrical system from the strain caused by high resistance in the circuit.
