10L0L 12V 250A Starter Solenoid Relay for EZGO Marathon 1979-1994 — 4-Terminal, Nickel-Plated Corrosion-Resistant

High‑capacity 12V 250A 4‑terminal starter solenoid relay designed to replace OEM units on EZGO Marathon (1979–1994) and compatible Cushman gas golf carts.

This heavy‑duty starter solenoid from 10L0L links your battery to the starter motor with durable copper contacts and a nickel‑plated cover to resist corrosion. Built with a standard flat mounting bracket and isolated ground, it’s intended for continuous automotive-style duty while fitting many recreational and industrial vehicles. The relay replaces common OEM part numbers including 16542‑G1, 889673, 70‑111224, and 3635820, providing a straightforward swap for repairs and restorations.

How does this solenoid improve starting reliability?

The 10L0L relay uses copper contact faces for better conductivity and a nickel‑plated housing to slow rusting, both of which help maintain consistent electrical flow to the starter. That means fewer voltage drops and more dependable engagement over time. It’s sized to handle transient peaks up to 250A while recommending continuous loads below 150A for long life.

• Copper contacts for low resistance and stable current transfer
• Nickel‑plated cover that reduces corrosion in moist environments
• 250A transient capacity to absorb high inrush currents
• Recommended continuous current under 150A to extend service life

Will this unit bolt into my EZGO Marathon or Cushman cart?

Yes — the relay is built to drop into the same mounting footprint used on many Marathon models from 1979 through 1994 and several Cushman, Columbia, and Jacobsen vehicles. The flat mount bracket and specified hole spacing match classic installations, and the isolated ground design prevents accidental chassis shorts. Check the OEM numbers and your cart’s wiring layout before installation.

• Standard flat mount bracket with 5/16 x 19/32 holes, spaced 2‑13/64" on center
• Direct replacement for listed OEM part numbers (e.g., 16542‑G1, 889673)
• Four terminal SPNO design matches common starter wiring schemes
• Isolated from chassis ground to avoid wiring hassles

Can this relay be used beyond golf carts—like in marine or industrial gear?

Absolutely. While optimized for vintage golf cart starters, the relay’s electrical capacity and corrosion‑resistant plating make it suitable for other 12V systems. It can serve forklifts, small tractors, winches, RVs, and many marine or motor starter applications where a four‑terminal SPNO solenoid is required. Always verify current draw and terminal layout against your equipment.

• Compatible with forklifts, tractors, marine, RV and winch applications
• Four terminal configuration fits common starter control circuits
• Use where continuous draw stays within recommended limits
• Corrosion resistance for outdoor and moisture‑exposed use

How should I match this relay to my vehicle’s electrical system?

Compare OEM part numbers, terminal arrangement, and mounting hole spacing to your current solenoid. Confirm your starter’s steady‑state current; if it regularly exceeds 150A, consider a higher continuous‑rating relay. For a direct swap, ensure the 4‑terminal SPNO layout and isolation match your cart’s wiring harness.

• Verify OEM cross‑reference numbers listed by 10L0L
• Confirm mounting hole spacing and bracket type
• Check steady current draw—keep continuous loads under 150A
• Match terminal labels and wiring orientation for safe installation

Who is this for: Owners, mechanics, and restorers of EZGO Marathon (1979–1994) and similar Cushman, Columbia, or Jacobsen gas carts who need a reliable, OEM‑compatible starter solenoid. It’s also a practical choice for anyone maintaining 12V starter systems in light industrial or recreational vehicles where a durable, corrosion‑resistant 4‑terminal relay is needed.
