Hi all
Thanks to everyone here, I have put together a working RPC and hope to test it this weekend. I have a general question about capacitor safety. My balance caps are wired per the fitch design and my understanding is they will discharge through the motor windings. The start caps are wired in two groups parallel like the fitch design with a bleed resistor across the last cap in the bank on both. I need to get in and clean up some wiring but I want to verify these capacitors are truly discharged before I touch anything. I have read that you can short the terminals with something and if no spark then they were discharged and you are safe. If they do spark then you have now discharged them and you are safe. This makes me ask “how big of a spark might I encounter?” Can I just use a jumper from the ground buss and touch it to the open cap terminals to bleed them off? Can I trust a meter to measure across the terminals and if zero volts then I am good?
Thanks for everything to this point and forward,
Nathan
