Car Forum / Honda Cars / November 200794 honda civic fried battery
My '94 Honda Civic is on its second battery this week. The car says it's overheating, but the only thing that I find wrong is the battery. The battery keeps frying. It starts smoking and acid starts dripping out. I've heard that it might be the alternator or something,so I changed the alternator on it the first time that it fried the battery, But, even with the new alternator it still fried the battery. but I don't know how to go about checking if it is the alternator. I would really like some help so I can fix my car as soon as possible. I don't' want to keep buying a new battery. Could it be an electrical problem? If so, how can i check it without spending too much money... PLEASE HELP ME! > My '94 Honda Civic is on its second battery this week.

If you're in the US, head on down to one of the big auto parts chains (Pep Boys, Auto Zone) and they'll throw a meter on your charging system for free. YOU HAVE ALREADY SPENT MORE THAN A GOOD MECHANIC WOULD CHARGE. That said you apparently have the knowledge to diagnose the problem so take it to someone who does... > My '94 Honda Civic is on its second battery this week.

Since the voltage regulator is inside the alternator (which was replaced), the next suspect is the Electrical Load Detector. Assuming no wiring problems at the alternator's connectors, of course. It would be wise of you to check the running voltage with a DVOM. If you don't know how to do that, bring the car to a mechanic. It will be far less expensive for you to that than try to fix this yourself. The longer you leave this, the more things will get damaged from the overvoltage, and the more you will spend.

Voltage at the battery should be around 14.5 volts while running and better than 12 volts when stopped. Anything higher that 14.5 volts will tend to boil the acid in the battery to the extant that it will smell. At 17 volts it is very noticeable. I suspect that your voltage is even higher and is indicative of a regulation problem. JT >> My '94 Honda Civic is on its second battery this week.

(and thus ALL the functions) I had to return it and got another that read OK. Check it against a new alkaline cell (1.5V) or a lithium coin cell (3V) before depending on it's readings.
