Frequently asked questions

What does the RTC3862 voltage regulator do?
The RTC3862 voltage regulator sits between the dynamo and battery on Land Rover Series II, IIA and III models with the 4-cylinder petrol engine. It controls the dynamo's charging output to prevent overcharging and hold a stable system voltage. It's rated for the 22A dynamo and uses Lucar push-on terminals.
What are Lucar terminals and why do they matter?
Lucar terminals are the flat push-on spade connectors this regulator uses to join the vehicle wiring. The RTC3862 has Lucar terminals, so it suits harnesses set up for push-on connections rather than screw terminals. Check your existing regulator's connections match before ordering.
Which charging system is this 22A regulator for?
The RTC3862 is rated for the 22A dynamo fitted to standard 4-cylinder petrol Series II, IIA and III Land Rovers. It regulates that dynamo's output and isn't intended for higher-output or alternator systems. Confirm you have the 22A dynamo setup before fitting.
