I recently changed my Alternator and changed my battery for the second time in a week. Something is has to be draining the battery and i think it could be the headlights, because at night the dashboard light and the headlights dim and the turn indicator becomes slow. i've been been told that it could be short if thats the case what can i do?

Re: 1992 Chevy Cav headlights and dashboard dim
What you want to do is go to an auto parts store and get a current tester.
You put it in line with your battery and keep removing fuses until the light goes out,then find out what components are on the circuit with the fuse.
Often times its a glove comparment lamp or trunk light.
Something that is trickle discharging .

To test the alternator, turn on the lights and every electric item you can. See if it gets worse. If so take it to a car parts place, they should be able to test the alternator right on the car. Also test the battery. If it is getting weak it wont hold enough charge for everything, even if the alternator is good.
Alternator. Have it tested with a voltmeter while on the car and running. Or take it off and have it tested. The current to run the car and the accessories is from the alternator when the engine is running. The battery light coming on alerts you that the alternator is not doing its job.
I recommend getting an actual voltage, ampres check to see what the alternator is putting out, volts and amps. You should be able to get the charging, battery load test and the starter draw all tested together. That's where I would start.
maybe something shorting out drawing power did u have alt tested before switching out to make sure it was bad- sum auto stores such as auto zone/advanced auto can do a load test on vehicle for free will show if their is an excess draw on elect or if new alt is faulty (does happen) check serpentine belt and pulleys belt may be slipping then check ground strap , starter for draw or some other accessory
dont change bulds check battery and alternator first at oreyllys or autozone they do it for free same problem with my 02 jetta light were dimming replace battery it still was doing that it ended up being the alternator. in my case my car almost died becauce los of power alternator was sucking all power from battery. in your case did you check the cables on your headlights make sure they are not loose.
your car is in denial.... Have your battery load testest. If it has any plate issues it can mislead the alternator regarding its state of charge abd, by all means make sure your battery cables are clean and tight. good luck
