Question about 1990 Ford Ranger SuperCab

Battery keeps running down, even a Brand New one.Any ideas what to check?

This is a problem on a 1990 Ranger Pick-up. I have purchased a brand new battery, and it has totally run down. Is there anything special I could check on, to try to find my problem?  I am at a loss as to what I should do now.   Any help would be appreciated. THANK YOU
Betty (a senior  person).

Need to have a mechanic check :

1: Alternator
2. Voltage Regulator
3. clean all main connections, battery terminals, ground cable connection to truck body, power to starter motor
4. test for battery drain (use an ampmeter with everything turned off, no key in ignition, all doors closed)  There should be NO current draw in this condition, if there is, you have a short that is not enough to trip a fuse, but enough to kill your battery.

unless both 1&2  are working properly you will continue to kill batteries.  Have the battery that is in there tested for free by autozone or another car parts store that doesn't chanrge for ths service.  The "new" battery you bought may or may not be good anymore depending on how discharged it got.



Sears auto service used to do this 1&2 above for free ... but then again the used to perform work that was not needed.  


good luck,
..ajm

Battery keeps draining already put in a brand new alletantor and brattery still draining and battery lights comes on and truck won't start


You would have checked the charging system before replacing the alternator, so I will assume the charging system is good.
If the battery is being discharged overnight or over a few days, you would need to disconnect it and check every circuit on the truck to find the drain.

MY 1995 JEEP BROKE DOWN ABOUT A YEAR AGO I JUST HAD 3 MAIN FUSES REPLACED A BRAND NEW BATTERY AND A BRAND NEW ALTERNATOR BUT THE BATTERY WON'T KEEP A CHARGE I HAVE A SHORT SOMEHWERE BETWEEN THE FUSE BOX...


Have you checked the charging of the alternator at the battery? (not by a parts store) Put a volt meter across the battery and check voltage while running. You should be showing 13.5v or better (not over 14) with accessories off, 12.5 or better with everything on including high beams. If you don't, chances are you may have a regulator problem. I don't know how you are checking draw, but you should be using an ammeter placed between either battery terminal and cable (cable removed from battery) Unplug each fuse and watch for a substantial drop in draw. That system will be the one with the problem...then, unplug each component served by that fuse (with fuse replaced) till the draw again drops. That will be the component that is pulling your battery down. You did check the simple stuff like sun visor lights and glove box light?

Stalls when giving it gas


these were hard to fix when they were new in 1990, question:::: does it run and rev-up hi normally in neutral/park??? with a timing light does the distributor show full advance???you claim "CUTS-OUT", like back-firing ??you may need to test the COIL, TPS (throttle position sensor) and LOOM to isolate the cause,.. try those and let me know the outcome....GL

Battery Not Charging on 1990 Ford Aerostar


I would say to change the alternator again even if it's new from the parts store it really is a rebuilt one try a different one . If the car is dieing while it is driving more than likely the alternator especially if things like headlights , radio ,ect.. cut off first.
