🔌 Function

Provides the electrical resistance required for circuit monitoring, signal conditioning or shutdown-system operation.

⚠️ Common Signs of Failure

• Emergency-stop circuit fault
• Shutdown warning remains active
• Open-circuit or short-circuit reading
• Engine will not enable or start
• Heat-damaged or broken resistor leads

🛠️ Service Notes

• Isolate the batteries before working on the circuit, and note the connections and any insulating sleeving, spacers or standoffs before disconnecting so it all goes back the same way
• Fit it in its original position with the same air gap around it; a resistor gets hot in normal use and must not be packed against a hose, harness or plastic part
• Where the original sheds heat through its mounting, make sure the mounting surface is clean and the same contact is restored
• Make the terminals off clean and tight with no strain on the leads, and protect the joint against damp in the way the original was protected
• A resistor rarely fails on its own — check the circuit it sits in for a short, a chafed lead or a failed component before fitting a new one
