Re: [b]8N Capacitor Questions[/b]
Dave, below is a quote from your earlier post:
He started having problems getting his Cub Low-Boy started and keeping it running. He called me the first time he had a problem starting it and after much diagnosis I determined that he had a bad capacitor. We replaced the capacitor and all was OK for a short time. When he had problems again I went back to look at the Cub and once again it looked like a bad capacitor and a replacement fixed the problem. He wound up buying capacitors by the box and when he had trouble with his Cub he would replace the capacitor. Sometimes he would only run for 50 feet and the tractor would quit. A capacitor replacement would fix it for a while. end quote:
Dave, from the above quote I concluded that the intermittent ignition switch (the basic problem) was knocking out the capacitor as well.
Sorry for the mis-understanding.
Soundguy is right on testing caps with an ohm meter.
You might want to re-test those capacitors the way he does it.
The cap absorbes then stores battery current sent from meter battery. Also, without discharging cap, same test done about an hour after the first will give some indication of well the cap holds it's electron charge. It should take no more current from meter. This test will give some indication of insulation quality between the cap plates.
Analog ohmeters are better then digital ones for this job.
cheers,
