Troubleshooting Electrical and Starting Issues on the New Holland LS170 Skid Steer
#1
The New Holland LS170 and Its Compact Loader Legacy
The LS170 skid steer loader was introduced by New Holland in the early 2000s as part of their L-series compact equipment line. With a rated operating capacity of approximately 1,700 pounds and a 60-horsepower diesel engine, the LS170 was designed for landscaping, light construction, and agricultural tasks. Its compact frame, responsive hydraulics, and mechanical simplicity made it a popular choice among small contractors and farm operators.
New Holland, founded in Pennsylvania in 1895, became a global brand through its merger with Fiat and later CNH Industrial. The LS170 was one of the best-selling models in its class during its production run, with thousands of units sold across North America and Europe.
Common Electrical Problems and Starting Failures
One of the most frequent issues reported with the LS170 involves intermittent starting, electrical dead zones, or complete failure to crank. Symptoms include:
  • No response when turning the ignition key
  • Clicking sound but no starter engagement
  • Dash lights flickering or failing to illuminate
  • Starter motor spinning without engine turnover
  • Machine starting only when jumped or bypassed
In Alberta, a contractor experienced a situation where the LS170 would only start when the battery was jumped directly to the starter solenoid. After inspection, the issue was traced to a corroded ground strap and a faulty ignition switch.
Key Electrical Components to Inspect
When diagnosing electrical issues, focus on:
  • Battery terminals and cable integrity
  • Ground strap between engine block and frame
  • Starter solenoid and relay connections
  • Ignition switch contacts and harness
  • Safety interlock switches (seat, boom, parking brake)
  • Fuse panel and blade fuse condition
  • Alternator output and voltage regulator
The LS170 uses a 12V electrical system with a conventional starter circuit. A weak ground or high-resistance connection can prevent sufficient current from reaching the starter, even if the battery is fully charged.
Bypassing and Testing Techniques
To isolate the fault:
  • Use a multimeter to check voltage drop across the starter circuit
  • Jump the solenoid directly from the battery to test starter function
  • Bypass the ignition switch using a remote starter button
  • Disconnect safety switches one at a time to test continuity
  • Inspect wiring harness for abrasion or rodent damage
  • Clean all terminals with wire brush and apply dielectric grease
In Shanghai, a fleet manager added a dedicated ground cable from the battery to the starter mounting bolt on all LS170 units. This eliminated intermittent starting issues caused by frame corrosion and improved reliability in humid conditions.
Preventive Maintenance and Electrical Upgrades
To avoid future problems:
  • Replace battery every 3–4 years regardless of cranking ability
  • Inspect and clean terminals monthly
  • Upgrade ground straps to braided copper with sealed ends
  • Install weatherproof fuse covers and relays
  • Use marine-grade connectors for exposed wiring
  • Add a voltmeter to monitor system health during operation
In Ohio, a contractor retrofitted their LS170 fleet with ignition switch covers and sealed relays. This reduced electrical failures by 70% over two seasons and improved cold-weather starting.
Field Anecdote and Practical Insight
In Baghdad, an LS170 used for canal maintenance failed to start after a rainstorm. The operator discovered water had entered the fuse panel and shorted the ignition circuit. After drying the panel and replacing the fuses, the machine started normally. A simple plastic shield was later installed to prevent future intrusion.
Conclusion
Electrical and starting issues on the New Holland LS170 are often rooted in poor grounding, corroded terminals, or worn ignition components. With systematic testing, targeted bypass techniques, and preventive upgrades, operators can restore reliable performance and avoid costly downtime. Whether grading soil, lifting pallets, or clearing brush, a properly maintained LS170 remains a dependable partner in compact jobsite operations.
