What Is the Club Car 103572501 Solenoid and How Does It Work?
The Club Car 103572501 is a 36V solenoid designed for golf carts and utility vehicles. It acts as a heavy-duty electrical switch, controlling power flow between batteries and the motor. This OEM-rated component ensures reliable acceleration and directional control, with copper alloy contacts for durability. Compatible with DS and Precedent models, it’s critical for preventing electrical system overloads.

How to Identify a Faulty Club Car 103572501 Solenoid?
A failing solenoid often causes intermittent power loss, clicking noises without movement, or complete failure to start. Test it with a multimeter: if voltage doesn’t pass through terminals when activated, or shows resistance above 0.4 ohms, replacement is needed. Physical signs include melted housing or burnt smell from overheated coils due to arcing contacts.
Which Vehicles Use the Club Car 103572501 Component?
This solenoid works with 36V Club Car models including DS (1982-2004), Carryall 1/2/6, and industrial utility vehicles. It’s incompatible with 48V systems or IQ Plus models with regenerative braking. Cross-references include Curtis 25864-G01 and White-Rodgers 586-118121. Always verify compatibility using the VIN or manufacturer’s wiring diagram before installation.
Common applications include turf maintenance vehicles at golf courses, airport baggage tugs, and campus security carts. The 103572501 excels in fleet environments requiring daily operation – its vibration-resistant design handles rough terrain better than aftermarket alternatives. For older DS models (pre-1995), technicians recommend upgrading the mounting bracket to prevent terminal stress. Recent field tests show 98% compatibility success with 2001-2004 DS Electric vehicles when paired with factory controller PN 102528901.
What Are the Technical Specifications of 103572501?
Rated for continuous 100A/36V operation with 950A inrush capacity. Features 3/8″ terminal studs, IP67 waterproof rating, and operates at -40°F to 185°F. The dual-stage coil (20W pull-in/8W hold) reduces energy consumption. Compared to aftermarket alternatives, OEM solenoids use military-grade phenolic resin housing and cadmium-plated steel brackets for vibration resistance.
| Specification | Detail |
|---|---|
| Coil Resistance | 42Ω ± 10% |
| Contact Material | Copper-Tungsten Alloy |
| Activation Time | <0.2 seconds |
| Weight | 1.8 lbs |
The cadmium plating provides superior corrosion resistance in coastal environments, while the 0.15mm silver nickel contacts maintain conductivity through 100,000+ cycles. Field data shows 23% better heat dissipation compared to standard brass terminals.
How to Install the 103572501 Solenoid Safely?
1) Disconnect battery cables negative-first. 2) Remove mounting bracket bolts using 5/16″ socket. 3) Label wires with tape markers for accurate reconnection. 4) Install new solenoid with dielectric grease on terminals. 5) Torque nuts to 12-15 lb-ft. Avoid positioning near heat sources. Test activation voltage (minimum 30V) before full reassembly to prevent premature failure.
Where to Buy Authentic Club Car 103572501 Parts?
Purchase from authorized dealers like GolfCartGarage.com or Certified Parts Corp. Genuine parts include laser-etched serial numbers and come in Club Car-branded packaging. Counterfeit alerts: watch for mismatched terminal colors (authentic uses brass, not chrome) or missing the “Made in USA” stamp. Bulk purchases (5+ units) typically save 18-22% through wholesale golf cart suppliers.
Expert Views
“The 103572501’s dual-stage coil design reduces battery drain by 40% compared to generic solenoids. We’ve seen these last 8-10 years in commercial fleets when properly maintained. Always pair it with 4AWG cables – undersized wiring is the #1 cause of solenoid failure we diagnose.”

Conclusion
The Club Car 103572501 is a precision-engineered solution for 36V electrical systems requiring robust current management. Through proper identification, installation, and sourcing practices, users can optimize vehicle performance while avoiding costly downtime. Regular maintenance checks every 250 operating hours significantly extend component lifespan.
FAQs
- Can I Use a 48V Solenoid in My 36V Club Car?
- No. Higher voltage solenoids have different coil resistance values (typically 90-110Ω vs 36V’s 40-50Ω). Using mismatched components risks incomplete contact engagement and accelerated contact welding.
- How Often Should Solenoids Be Replaced?
- Average lifespan is 5-7 years under normal use. Commercial applications may require replacement every 2-3 years. Monitor activation time – if exceeding 0.3 seconds, preemptive replacement is advised.
- Does the 103572501 Work With Lithium-Ion Conversions?
- Yes, but requires adding a pre-charge resistor (minimum 500Ω 25W) to prevent contact arcing from lithium batteries’ near-zero internal resistance. Consult conversion kits for specific wiring modifications.
