So I just got the bike and havent been able to ride for a few days and decided to play around with the PCIII today. I checked out the map and loaded a few and zeroed the throttle then I got to nosing around the firmware versions. I had the bike running and tried to upload the firmware and the bike died and I got a device error code on the PCIII. No prob, it prolly needs the 9v power supply hooked up to do that, I say to myself. So I rob a 9v outta the house somewhere and plug it in. Two green lights light up on the PCIII and I think I am back in business...hit upload firmware button and bang...lights go out and I get an error code. Now bike wont start...laptop sees the powercommander but will not communicate...and I can not reset it using software. My last hope is that my two batteries I tried just didnt have the juice. I read that a PC3 will zap the 9v in about 20 min, so i figure my two 9v I had(one from my alarm clock and one from my gas grill)where already below the threshold of usefullness to the PC3....I hope. BTW my second bat I tried read 8.65v I think.
