How should the radio isolating switch be used on my Boxer van?
Ans 15: It is important that the radio isolation switch, fitted to the Nuevo/Talisman & Executive vans, is always left in the “off” position when the radio is not being used, otherwise a very small drain may result from the vehicle battery to the detriment of starting the engine. NB Earlier Boxer vans, without the radio isolation switch, can suffer from the radio switching off after 20 minutes. Ideas Sheet No 63 (see Technical) offers an way of obviating this problem.
