I have a 2005 Dodge ram 1500 slt quad cab. multiple upgrades nothing seems to work right please help?


Think you have voltage regulation hassles. Assuming your connections are squeaky clean and have very low resistance, your charging voltage should be at least 14 volts. And when you turn on heavy drain accessories the voltage drop should be minimal. 13 volts is much too low.

I live in an apartment that has Airtemp central air. The unit blower runs but the air is barely cool. Maintenance sys there is nothing wrong with the unit. What could cause this problem?


air temp should drop 15-20 F across the a/c coil a rule of thumb i use is air temp out of the vents 10-15 F less than room temp on thermostat if the air out of the vents isnt that cold the a/c is either leaking and undercharged or return air temps are to high. is the inside unit in an attic? return leakage in this situation can cause high supply air temps but look like every thing is ok when pressures are checked at the outside unit

New batt reads 12v on meter push button and tries to start. can hear everything cranking and turning briefly then nothing. put trickle charger on it for ten min and starts right up. what is the issue, do...


Did you put the acid in the battery or did the store do it for you? Or is it gel? Did you charge it up overnight? The voltage should read 12+, more like 13. The starter needs all of it to get going , then kicks back and enjoys the ride. And charges back up. Did you clean the terminals good? Check the electrolytes in the battery. Get one of those floaty ball things, they work great. But make sure it gets a full charge. Hope this helps.

The batt lite has come on and won't go off. replaced the battery (very old) no change. several months ago had a charge sys check - they found nothing wrong. need to fix this


you may have a voltage regulator going bad internally on the alternator. i would take the alternator off and have it tested off the car.

1994 saturn sl 1.9l 5 speed wont sart now. ran a few times poorly


try checking your alternator, charge the batt and then try starting car if the car starts pull off your batt terminals and if car does stall out then 9 out of 10 the alternator is shot, if it doesn't then get a ac/dc tester then put it to the post on the alternator and if it is not putting out 13.8 or 14.o then you have to try to find a short, a bad wire, or a bad ground and if you cant find one then pull it out and bring it to a aoutozone or a advanced outo and have them bench test it.
