rawsondsr Posted April 8, 2010 Share Posted April 8, 2010 Got hold of a 52mm VDO rev counter. trouble is i have no idea which connection is what and if i need them all? Any help would be appreciated Quote Link to comment Share on other sites More sharing options...
western Posted April 8, 2010 Share Posted April 8, 2010 Terminal marked as 2 connects to Alternator 'W' terminal, this is the rpm signal from alternator to rev counter Terminal marked as + [positive] = 12v ignition controlled feed [any of the White wires behind the instrument pack will do the job] Terminal marked as - [negative] = Earth connection the illumination can be connected into the existing gauges illumination via the red/white trace wire & earth the 3 small dip [slider] switches set these to 1 & 3 up & 2 [centre] down that should get it working, mine is fitted next to the speedo.

western Posted April 8, 2010 Share Posted April 8, 2010 IIRC in mine was a 1.2watt capless bulb, Halfords or any car spares shop would have some, don't know if there's a led to fit. Quote Link to comment Share on other sites More sharing options...

Crazy LEDs The only problem is they are so bright they can make a bright spot in your gauge. You may need a small circular diffuser directly above the centre of the LED face to prevent a bright spot.

Ex Member Posted April 8, 2010 Share Posted April 8, 2010 There is also an adjustment screw on the side for fine tuning the setting. I would not use an LED. The stock lights are very bright. Quote Link to comment Share on other sites More sharing options...
western Posted April 8, 2010 Share Posted April 8, 2010 I'll have to look at mine for that screw, just for interest sake as it doesn't need any more adjustment. Quote Link to comment Share on other sites More sharing options...

Dads Toy Posted April 9, 2010 Share Posted April 9, 2010 You can get most of the VDO range from here http://www.etbinstruments.com/VDO_Range.htm#VDO_Electronic_Tacho but the tacho's go to 6000 and I sure wouldn't want mine revving that high!

David Sparkes Posted April 9, 2010 Share Posted April 9, 2010 Was it the 52mm size you were after, or the specific VDO 52mm rev counter? If it is the 52mm size, McGill Motorsport carry an almost bewildering variety - VDO Gauges in the UK can be found (courtesy of Google) at http://www.etbinstruments.com/VDO_Range.htm OOPS, a duplicate link!

shauniedawn Posted April 10, 2010 Share Posted April 10, 2010 Having seen this thread, I liked the tacho that much I wnet on Ebay and found an identical one for £34 inc P&P striaght away . It's not arrived as yet, but described as new with some minor scratches to the bezel. Thanks for the heads up Quote Link to comment Share on other sites More sharing options...
rawsondsr Posted April 17, 2010 Author Share Posted April 17, 2010 went to install mine, did all the wiring, plugged it in and nothing, thought i'd got the wrng terminal on the alternator, so rewired it so i had it in my hand while moving the wire around the alternator, turns ou one of the power terminals on the unit was dodgy, a bit intermittent and loose. a bit of shaking would make it work now and then, so contacted seller, same ebay fella as listed above,, the £34 unit and he sent another onwards and its all good now switch setting i have it on all 3 down giving me a 750-800 to 3800 rpm rougly range, thus using all of the dial unlike many units you see that go up to 8k! that appears to be the best setting from what i saw Quote Link to comment Share on other sites More sharing options...
western Posted April 17, 2010 Share Posted April 17, 2010 good to read the seller replaced the dodgy unit without any problem, glad it's in & working. Quote Link to comment Share on other sites More sharing options...

shauniedawn Posted April 18, 2010 Share Posted April 18, 2010 Tested mine today before fitting. Worked a treat on the switch settings the same as you rawsondsr. Here are a couple of photo's. Shaun Quote Link to comment Share on other sites More sharing options...
