Message: [QUOTE="MeTo, post: 1499972, member: 23681"] I talked to Jay, asked if he would tell me which contacts on the PCM provide the 5 volts to the Hydra. NO, it's proprietary! Thanks, I'm sure someone can reverse engineer the Hydra from that bit of info. Jay also told me that they can test PCMs, but they will not repair them due to liability issues. My Hydra would not light up when connected to the PCM. It would light up when connected to my laptop via the USB cable. So I talked to Jon (Swamps guru). The PCM was fine. The Hydra had an issue with the D2 diode that the input 5v power goes through to protect the Hydra from reverse polarity and the C2 1.5 microfarad capacitor which smooths out ripples and spikes (voltage regulator) in the input voltage. $50 + shipping and it's running again.
