I just put a 2" hockey puck lift on my frontier, seemed successful when I lifted it, but when i was done i went to start it just for the sake of it. I went to turn it over, and the battery was dead, so I charged the battery for about 5 minutes when i noticed the charger shut off. I checked the voltage and was at 13.3 v, which seemed unusual for it to charge so quickly but nevertheless i went to start it and dpa 5 turned on but was incredibly loud and alarming, so i shut it off immediately. I came back half an hour later and the battery was dead again, so i put the charger on it and left it. I tried again today and the battery was at a pretty usual 12.6 volts. I started it again and i checked the RPMs because i thought maybe when i lifted the cab the line to the gas pedal was lifted with it, but the RPMs were resting between 1000-2000, which is typical for it. I don t know what the problem is, but i dont want to have to take off the lift just to see, any ideas?
