                Posted - 26 Aug 2016 : 20:17:31  Hi there, Just looking into converting the Rapier to negative earth so I can fit an alternator. The rev counter says positive earth only, what do I need to do to allow me to switch it? I have switched it on a car before but it wasnt as advanced as the Rapier! 
  Many thanks, Tom |

                Posted - 27 Aug 2016 : 14:39:35  I'm guessing you have a Series IV as earlier cars had a mechanical rev counter, so it did not matter. I would say you need a rev counter from a Ser V as these were neg earth, if I remember correctly from another thread that our well informed member 'pruyter' advised on. I guess a + earth rev counter could be changed, but may not be cost effective? I'm sure there will be other more knowledgeable responses too! Cheers. G. |
