Upgrade your classic car’s unreliable mechanical stabiliser with the plugpal 10V Solid State Voltage Stabiliser with Mounting Bracket, designed specifically for negative earth vehicles. This modern electronic replacement offers a dependable solution for classic cars from the 1950s, 60s and 70s that originally used bi-metallic contact breaker voltage stabilisers.

Suitable for classic vehicles from:

• MG
• Triumph
• Jaguar
• Lotus
• Rolls-Royce
• Daimler
• Austin
• Morris
• Ford

…and many other classic British and European vehicles.

Reliable 10V Solid State Regulation

Unlike original contact breaker stabilisers that fluctuate with temperature and age, this unit uses modern semi-conductor components to deliver:

• Stable, constant 10V DC output
• Accurate fuel and temperature gauge readings
• Consistent performance regardless of engine revs or electrical load
• Improved long-term reliability over mechanical units

Maintain classic originality while dramatically improving gauge stability.

Integrated Mounting Bracket Design

This version features a metal mounting bracket that:

• Secures the stabiliser directly to the vehicle body
• Provides the required ground connection
• Ensures proper operation (must be bolted to chassis to function)

Product details:

• Two-wire configuration:
  • Red wire – +12V input
  • Green wire – Regulated +10V output
• Ground is achieved through the mounting bracket
• Metal enclosure doubles as a heatsink
• Adequate wire length for flexible mounting options, approx 100mm.

Supplied with:

• Male 6.3mm spade terminal on +12V input
• Female spade terminal on +10V output
• Adapter lead included if a male output connection is required

Alternative terminal configurations may be available on request.

Technical Specifications

• Output Voltage: 10V DC (regulated +- 0.5V)
• Vehicle Compatibility: Negative earth systems only
• Output Current Range: 5mA – 1A
• Components: Constructed with a Texas Instruments LM2940T-10 voltage regulator and the manufacturer recommended capacitors
• Recommended Load: Up to two gauges (fuel and temperature)
• Construction: Vented metal casing acting as heatsink with regulator mounted on thermal paste 
• Connections: Professionally crimped (not soldered) to prevent vibration-related stress fractures
• Protection: Adhesive-lined heat shrink for improved moisture resistance

Designed specifically for classic automotive electrical environments.

Direct Replacement for Original Units

Compatible with stabilisers carrying part numbers:

• BR1307-00 NEG
• BHA4602
• 148876A
• BMK1539A

Ideal for restoration projects and reliability upgrades.

Important Notes

• Outputs 10V only.
• Must be securely mounted to the vehicle body to operate correctly.
• Suitable for negative earth vehicles only.
• If being installed not using the original loom stabiliser connections, a fused 12v supply is advised.
