MOTO1988 48V 4-Terminal Starter Solenoid Relay for Yamaha, EZGO & Club Car — JR1-H1950-00 Compatible, Heavy-Duty Replace

This heavy-duty replacement starter solenoid is built to the JR1-H1950-00 specification and fits a wide range of 48V electric golf carts from Yamaha (G19, G22, G23, G27, G29), select EZGO Shuttle and Titan series, and Club Car DS & Precedent models.

What wiring and electrical specs should I check before installing?

This relay uses four terminals for power and control in 48-volt systems; ensure your cart’s wiring layout matches the relay terminal pattern. Verify battery pack voltage and terminal clearances and follow safe-disconnect procedures before touching connectors.

• System voltage: 48 volts nominal
• Terminal count: 4-terminal configuration for standard starter circuits
• Installation prep: disconnect batteries and note wire positions before removal
• Tools: basic hand tools and insulated pliers recommended

Will this part restore a cart that won’t start, and what should I expect after replacement?

Replacing a failed solenoid often resolves starter-engagement issues caused by worn contacts or stuck coils, but it won’t fix unrelated battery, motor or controller faults. After installation you should expect consistent starter engagement and reduced intermittent starting problems if the solenoid was the cause.

• Typical symptom improvements: reliable starter operation and cleaner contact switching
• Symptoms not fixed: depleted batteries, defective controllers, or wiring damage
• Post-installation check: inspect for secure bolt connections and no heat or sparking
