I attended Goodwood FOS on the Friday and, having waved goodbye to another Supersports, found my car refused to start. Fortunately the kind people there offered to jump the car and I borrowed a set of leads from Ken Blocks team. The car made it home, just starting for much needed fuel but was completely dead the following morning.
Since then I've changed the battery and it seems to be keeping charge. Typically she sits on trickle charge so I was surprised to have any issues. However, I've noticed two things:
1. The amp whines when the radio is on - getting louder as I accelerate. It disappears when the radio is off so it certainly isn't the gearbox (my first thought). Is this normal? The radio has been upgraded and there's a second wire to the positive battery terminal which I'm guessing is for audio bits and pieces.
2. The car has the heater button lit all the time whether on or off. Could this be due to a bad earth? The light isn't as bright as when the switch is properly on but light enough to notice.
