The battery’s only a year old; and came with a year’s warranty. I will get a multimeter soon and use it to find out what’s going on with the battery. Thanks for your help. — http://www.munted.org.uk – updated 28/03/2003. If you want efficiency, use C. If you want to suffer, use C++.

So first of all: Does the alternator light work when switching on ignition without starting the engine? If not, there might be a problem with the clables. AAssuming the indicator light is correct, points a not burning indicator light on the fact that the generator does not get energizing current. In this case probably the carbon brush conductors and/or the voltage regulator might be worn / defective. So you might have a look on what happens when turning the start key to ignition. — Mit freundlichen Gr
