Aaron Posted August 30, 2012 Share Posted August 30, 2012 Hey dudes, just wondering if this will help with cold starts in the morning. http://www.trademe.co.nz/motors/car-par ... 722175.htm Also, would they be easy to install? Cheers. Quote Link to comment Share on other sites More sharing options...

azzurro Posted August 30, 2012 Share Posted August 30, 2012 they work by sensing the change in magnetic field from the dizzy cam lobes moving past the sensor to rest/fire the coil instead of the points opening and closing to do the same thing. they are as easy to install as replacing points, as this is basically what you are doing, and basically the only difference between models is the screw holes to suit. The dizzy rotor and cap still work the same as before to get the spark from the coil to the plugs so work best if these are good too. Only problem with them is if you have small lobes on the cam as the sensor will have problems accurately sensing them relative to the shaft, so they arnt as good an upgrade as they could be for my fiat for example Theyll still work, but not as good as they could (wobbly dwell times, which is the main 'performance' problem with points remain, the other problems of constant adjustment and maintenance are fixed). this pic shows difference between lobes for points and an electronic one - the electronic one ® has exaggerated lobes for the magnetic sensor, which i suppose you could make your lobes bigger with blobs of weld (lol) or machine one up, or steal necessary parts from a suitable electronic dizzy from PaP? they are also about $70 landed from overseas...
