Had to get another voltage regulator for my old Volvo V70. Checked YouTube (Robert) and proceeded to install with alternator in car.
Not much space to get at the alternator(Lucas) but managed up to the point of removing the alternator plastic cap.
Although I removed all the screws the cap could not be manoeuvred out of the engine.
I then removed the front inlet manifold and the rest was easy. The old regulator(burnt out) was held in by two screws and the new one fitted very quickly.
The engine turns over much more smoothly and battery is kept well charged from the alternator.
So far very pleased with the new Voltage regulator.
