Big smile on my face... my car battery died on me 2 days ago, so had it changed. Then noticed that the needles on Revs counter & Speedometer got stuck on max. So I googled it, found this 5 second solution, tested it. Fixed :-) ... me thinks that a garage mechanic might have told me they'd have to take both units apart and charge me accordingly... alas! Thank you :-)
