the cap on my CCPWM gets pretty hot after about 15 minutes. any idea why? its set to limit 13 volts and the duty lets it run at about 20 amps. the freq. is just set in the middle because I have no idea how to set it. I know if I have a bad connection because i get a high pitch sound and I can change the sound with the freq adjustment. Im getting a good meter in the mail today that may cheack freq.
