Q: i just but this truck privately and the ac will not blow cold air. when the system is running if you feel the evaporator and condenser lines in the engine compartment one is real hot the other is real cold just like they should be. this is my first dodge that i have ever owned and am not familiar with their systems. anyone have any ideas of what to look for myself before i spend the $$$ and take it to the shop gm used to have a solenoid valve in the supply side of the heater core that would shut off the flow of hot water to the core when the ac was in use. does dodge use the same type of setup thanks for any help. ron .

the maximum safe output for your alternator should be found stamped on the alternator body. it should be putting out about 15 volts most of the time if healthy .. and then supplies the amperage necessary for whatever else you happen to be running. we usually dont worry much about amps but volts. if you have anything using say 85 amps for any length of time you will see that something smoking after a while and your alternator will probably be smoking shortly. the max output of an alternator is meant to be for short periods of time like when jumping another car .. but it wont put out that max limit forever. the alternator will attempt to meet the demand put on it at any engine rpm .. the regulator/computer will attempt to maintain the voltage somewhere between 13.5 and 15 vdc and then the amps or current will vary depending on how many things you have turned on ... or how much charging the battery requires. if your vehicle has an alternator controlled by the computer then you should see 15 vdc at the battery assuming all wires and connections are in good shape or about 13.5 to 14.5 vdc at the battery for an alternator that is internally regulated. i have a 1999 dodge ram 1500 with a heavy duty package. i would like to know how can i find out what is the maximum safe amp output of my alternator at idle. i .
