Default Re: Schwinn Computer Question

Sounds like Schwinn and some of the better ones may be shielded internally and are better quality, as they are working for many folks. The ones I had were Hong Kong cheapies (you get what you pay for!). I personally think the problem is the field effect from the magneto, as the electronic speedos work by sensing a small permanent magnet passing a tiny detector coil sensor. But whether it is high voltage pulses from the ignition or magneto field effect...the fixes are the same! Isolate and shield.
