trendkill Posted December 4, 2010 Share Posted December 4, 2010 Can anyone tell me where on the alternator of a 3.9 v8 (serp) I attach the rev gauge wire? Also looking for a rev gauge, 2nd hand or a point in the right direction of buying new. Many thanks. Quote Link to comment Share on other sites More sharing options...

trendkill Posted December 4, 2010 Author Share Posted December 4, 2010 Cheers west - Maybe 2nd hand is the best option as im not spending £££'s on a blummin gauge Any ideas where i would plug one into my alternator aswell? Quote Link to comment Share on other sites More sharing options...

W terminal. Not all alternators have them. Be warned, if you buy a "petrol" or "v8" rev guage, it will quite likely not work with the signal a W terminal on an alternator produces. You can of course use the coil, as a standard "petrol" rev gauge does. Jsut make sure you can set the gauge for an 8 cylinder engine.

western Posted December 4, 2010 Share Posted December 4, 2010 your alt. may already have a 'W' terimanl under a rubber cover, if not you can fit a feed wire from on of the static windings bolts IIRC. Quote Link to comment Share on other sites More sharing options...
Mike Jenkins Posted December 5, 2010 Share Posted December 5, 2010 You can buy a generic gauge and just connect to the coil. I bought a Tim one that looks just fine in the dash. I replaced the voltmeter in mine. Quote Link to comment Share on other sites More sharing options...
