Had Alternator repaired he replaced everything in it, and installed new battery, lasted 1 hour this time. battery dead regulator failed.
Now I don't have a VAT-40 and I can only check the voltage on this. has anyone had problems like this on these ss's. Is there a relay that's causing the regulator to keep failing and draining the battery? I ready to try a NAPA Alternator to see if it's the rebuilder, but I can't see the same thing going out.
I will leave the plug disconnected until I can get it on a VAT-40
Could it be caused from it's security system, the LoJak?????
Help getting ready for the fire sale!!!

good choice on vehicle .. your alternator when the regulator goes bad will suck the battery to zero....... what you have to do is make sure the alternator is 140amp not the 105amp..... next before installing the alternator fully charge the dead battery with a 10amp charger..... do not force more than 10 amps into a dead battery or it will be damaged.....now if you have the 140amp alternator [cs144]and this is killing the regulator repeatedly then check for leakage of current at battery with engine off remove neg bat connection place ampmeter between neg bat terminal and ground wire terminal there shall be no greater than 50ma max.....now with fuse removal you should be able to find circuit resposible for draining the battery....if this is the case......where did the alternators come from? who is he ? if the alternators where installed and forced to charge dead battery this would explain some of these issues you have......
