You've cleaned & checked & tightened all your battery connections good, and looked for thinning wires at battery terminal ends? Check all the grounds (-) at other end of battery terminals, and make sure they are clean & tight. What voltage do you read at battery when engine running, and not running? Next time you have to boost it to start, try just connecting the (-) negative & see if it starts, if it does you have a bad ground connection somewhere.

    Also, if your alternator wasn't charging your new battery, sooner or later the car would quit running due to lack of voltage, so something is charging that battery. Like I said earlier, double check all connections where ground cable attached to engine or frame or wherever, and check connection at starter also.

check the drive belt for condition and tension as you drove on the battery only because the alternator was not working . The battery you replace was a good battery just needed charging. Putting the car in gear lowers the rpm's below that necessary to spin the alternator fast enough to keep the light off . When the alternator is needed the drive belt of some other failure in the alternator comes into play . have it checked out at an accredited auto electrician

The bottom fan belt on my 87 xtracab recently broke in the middle of traffic and those same warning lights came on immediately, so you might want to have the belts checked, especially the one driving the alternator.

All gauges went dead while driving, lights progressively dimmed and finally engine quit.

Your alternator died. You drove until your battery died also. You need a new alternator and a new battery. You might be able to get away with just charging your battery. Do Not jump start the vehicle and let the new alternator try to charge the old battery! Take the battery to a service station for testing and a charge. Install the new alternator and then install the charged battery not vice versa and you'll be fine.

Something electrical is draining battery on 1987 XJ6;

Have you checked the alternator? The alternator may not be charging the battery. With engine running, check the voltage at the battery (it should be ~14V). If it's less than that, your battery won't charge properly. You can take your alternator to auto store to have it load tested also to be sure. Sometime alternator issues don't show up until it gets hot. Defective alternators have also been known to drain the battery after the car has stopped.

Alternator in 1987 toyota corolla

The alternator is there to support the electrical loads of the vehicle plus recharge the battery after starting. To be sure you can identify the problem you will need a voltmeter (multimeter) Check the battery voltage with the engine switched off - you will see 12.0 to 12.6 volts depending on the state of charge. Start your engine and the voltage at the battery should go to about 14.2 volts. If it does, the alternator is charging the battery. If the voltage stays unchanged you have an alternator problem. Check drive belt and wiring at the back of the alternator - If all OK you will need to remove the alternator and replace it or have it repaired. span.jajahWrapper { font-size:1em; color:#B11196; text-decoration:underline; } a.jajahLink { color:#000000; text-decoration:none; } span.jajahInLink:hover { background-color:#B11196; }

check for blown fuses& make sure the red wire to alt. is getting 12volts. also ford uses fusible links witch look like regular wires. usually you can tell by feeling the wire itself if it feels squishy and when you pull on it it stretches chances are its bad. try an ohm meter at each end no continuity no connection

The only thing I could suggest is that if you bought a remanufactured alternater you may have gotten a bad one. It tends to be hit or miss with any remanufactured part.
