996 Jumpy Tach

  1. Hi all,

    I'm looking at a 996 that's for sale near me. It's got a rev counter needle that jumps around a bit, especially at idle. Is this a common issue or likely an easy fix?

    I'm likely to have lots more questions if this fits ahead!

    Cheers,

    Jm
     
  2. Regulator
     
  3. That was quick!

    Sounds expensive...
     
  4. Not very but an easy fix and a great bargaining point.
    Measure the voltage output across the battery at around 2krpm...should be around 14V..if not, the regulator/rectifier could be knackered.

  6. Great, cheers gents. Think I'll start another thread with all of my other questions...

    I normally hang out in the Pani and Hyper forums. You guys are lightening quick compared with then!

  9. I had a jumpy tach

    The plug on the rectifier can also get dirty causing a weak contact , and an old battery does not help

    I removed the plug on mine and soldered the wires to ensure I have maximum conductivity , solved the issue
