Hi all,
Having had flat battery issues in the past, I decided to invest a few quid in a voltmeter to monitor my battery and how much charge the alternator is giving.
I don't know where to connect the live wire to get the best reading from the battery, I tried the spoiler switch as it is conveniently located a few inches from the voltmeter, but the voltage reading doesn't match my multimeter reading against the battery.
Cheers
