GPX regulator/rectifier

Discussion in 'Technical and Troubleshooting Torque' at netrider.net.au started by Banana Fred, Sep 6, 2007.

  1. My bike battery is no longer capable of cranking the engine if it doesn't fire up after 2 or 3 attempts. This arvo after work, I had to roll start it to fire it up and I also took a moment to run a digital meter across the terminals while it was idling. I got 12.5v.
    It should be at least 13.5v and above, much like a car battery but no amount of revving produced an increase in the voltage so I'm thinking it's no longer recharging the battery properly.
    My question is; what does a regulator / rectifier cost for a GPX? A few bucks? Or am I giving up lunch for a week to pay for it?
