I own a 1990 Mercury Cougar Bostonian... what is the correct size battery recharger for this car? Schumacher is the best brand I think. Thank you in advance.


Most chargers have settings for different size and type of batteries and also have regulators to prevent overcharging. Don't buy the very cheapest, but the $60 (approx) units are good choices for most hobbiest uses.

Charger is not charging


Charger? you must mean the alternator. It has to put out at least 13.8 volts to charge a 12 volt lead acid battery. There are 3 diodes in there and a chip called a diode trio. Did you replace the voltage regulator? While you had it apart you needed to check the stator (the wired cage that is fixed and the rotor which spins. If either is black in color instead of copper it is fried.)
The best thing to do for that van is get a replacement alternator from one of the parts houses and make sure you get one with a lifetime warranty! They are very hard on alternators as the under hood temp is so high.

My battery light sensor came on so I took my car to autozone to check the battery,it said good battery so what is the problem??


The warning light is for the alternator or something in the wiring between the alternator and the battery.
It means the alternator is not charging the battery.

Location of 1972 corvette voltage regulator in car


Hello: The voltage regulator is inside the alternator (generator) The generator can be overhauled. The brushes, diodes, rectifier bridge and voltage regulator all can be replaced along with the stator, rotor and bearings although now days it may be cheaper to replace the alternator.

Rough idle but runs good.battery drains overnite


This could be a number of things one is not necessarily connected to the other.. Check to see that the battery is in good condition (load test for bad cell) check to make sure no lights are remaining on (trunk or glove compartment lights) make sure the alternator does not have a bad diode or rectifier bridge (disconnect the battery wire from the alternator then touch it to the terminal you just removed it from and see if there is any spark, if there is the alternator needs to be replaced.. Is there a check engine light on? If there is then a code will be stored in memory of the computer which will greatly expedite a diagnosis to the rough idle.. I would check for broken vacuum hoses or loose clamps between air filter and engine connection.

How to bypass the Generator Battery Control Module on 2006 Chevy truck so that I can get alternator to put out 14 volt all the time.


The alternator on your truck is a self contained unit. The voltage output is controlled by a rectifier bridge and diode trio. If you ground the test point on the back of the alternator (near positive post) it will go full out. Remember if you run at full output constant, you will damage e.c.m., g.e.m., and battery. You will also shorten bulb life and possibly damage radio.

Slow drain on the battery. Have isolated to the extra two wires that connect where the battery hooks up to the alternator. Unsure where or what those two wires are feeding. They are hooked up together on a...


tell you what you do, because i think the alternator may be the problem, remove all the wire from that connection and tape them together good, and see if batt still goes dead, if it doesnt then replace alternator. hope this helps.

Battery light stays on


the battery light has nothing to do with the battery itself, it is indicating that there is a problem with the alternator that charges the battery, most likely a defective rectifier bridge diode has failed.

Meter Explanation


You are correct on all accounts. A high number means you dying battery is sucking more juice from the Schumacker. A low number means the battery is not as thirsty. That's how I always think of how to read the meter on mine. Slow charge is a better, deeper charge. The quick charge will get you going, but you should maybe follow it up using the normal mode - car alternator and prolonged drive time. I never use quick charge, personally.
