Hi The red warning light in the tacho has started to come on when the engine it hot. It first started at the Anglesey Sprint when we had to spend ~1hr waiting in line with the engine idling but would clear if the engine was rev'd. Since then, it has started to come one when driving, particularly when traveling at modest speed (in town, stuck behind other cars at 40-50mph). It does clear when driving a little more enthusiastically (rev's pick up). However, even that is not working now.. I did check the voltage at the battery when idling & it was ~14.5V so alternator seems to be doing its stuff. Any thoughts? Cheers Jon
