1988 toyota truck won't charge

Alternator, battery, all terminals and grounds- all are good. Charge light in dash is on, dash guages and windshield washer are off, and battery is not getting charged. Alternator belt is good. Bad charging system relay? Plug-in connector on alternator bad? Any way to figure it out without trial and error replacement?

    Alternator has been tested. Main wire connector to alt. looks good and I cleaned well. Plastic plug-in connector looks fine but has white paste-like substance in some of the female sockets that I took to be contact paste. Is this my problem? Should I clean it out w/electrical cleaner and file contacts?

  • avasen Apr 24, 2009

    Have 12v continuity to battery from alt. Regulator is integral to alt; it all tested out fine at napa. I will clean all contacts in plastic connector tomorrow ; if that doesn't do it I will replace connector. I will let you know.

Connect the voltage meter lead the same way you would in a battery static voltage check, Start engine (do not drive) at engine idle the voltage should be between 13.6 to 14.3 volts.
>>>>> If not the alternator may need replacing.

Is the alternator new? has it been tested? U need to be 100% sure on this, if U are then the connectors to the alternator are the next place to look, check for burnt discolored connector terminals and burnt looking plastic shells on the connector.I CONTACTED A FREIND WHO KNOWS THIS MODEL AND HE SAYS THE ALTERNATOR CONNECTORS CAUSE THIS ISSUE, U SHOULD BE ABLE TO BUY A REPAIR CONNECTOR FROM THE DEALER

How do i fix my 1988 Toyota 4WD EFI charging system?


Make sure the circuit is good from the battery to the cable connection on the alternator. The main fuse may have blown which completes the circuit and powers the things you have mentioned.

1986 Chevy nova. I've just replaced the battery,alternator, and starter. The issue I'm having is that the car will not charge. I've checked the fuses and they are good. I've checked grounds and battery...


I have no experience of your car but starting and charging circuits are fairly universal.

For a lot of years the charging system of the majority of cars and trucks only comprised an alternator connected by a single wire to the battery live and an "earthy" terminal to connect the ignition, battery or charge light wire. The alternator had to be grounded and some manufacturers mounted them in rubber bushes so a good earth or ground lead had to be bolted to the alternator casing.

There have been some slight variations. Some alternators were "battery sensed" rather than "machine sensed" and needed an extra wire to provide voltage to the internal regulator and the Japanese used electro-mechanical regulation for a long time after the rest of the world adopted internal electronic regulation. These modern times have brought more charging developments with the addition of intelligence, black boxes and the like.
A few of the older machines (AC Delco, Lucas) had an extra large spade terminal at the rear which needed to be grounded. These machines caused some confusion as to a casual inspection they appeared identical to other machines where the terminal was live and should not be grounded.

If your alternator has the required ground and live and the ignition light is working and the wire connected and any other sensing wire is connected and providing the required voltage the charging system cannot fail to work if the alternator itself is good.

I suggest you sort out your brake lights which is probably a faulty or maladjusted switch or misplaced or shorted wire, most likely in the region of the switch.
If it is the switch, disconnecting it should kill the lights.
After that it will be time to double check the connections to the alternator and verify each wire has the correct potential.

Most parts stores carry these. if not may have to call your dealer. Good luck.
But you really need to check out closely and find what blew the fuse.

I changed the alternator on my honda accord and now it will not hold a charge ? The battery light comes on now. the battery is fine it holds a charge. HELP !!!!!!!


Check to make sure that all the connectors are hooked back up correctly and that the ground wire has a good ground connection. If all connections are good then it could just be a bad alternator, I've seen it happen once in awhile. Hope this helps!

1988 Toyota pickup will not start after changing altinator. no lights in dash and will not start. battery charging head lights work great


Check fuse-able links, check by gently pulling apart the wires on either side of the fuse-able links, be sure to try to check them all, it helps to mark the ones you check to avoid constant rechecking and getting "lost" on which ones have been checked. Hope this helps.

1982 toyota land cruiser Tail Lights not working i have tested all mu fuses checked the wires the bulbs are good my tail lights stayed on for about 5 min after i turned off the truck then just stoped...


Do you have dual battery wiring??? I had the same problem with my cruiser when I first purchased it.
The main battery was connected to the starter motor, headlights, indicators and a couple of other lights. Although not installed, the positive terminal of the second battery was wired to the alternator and tail/position lights. But because the battery was not there the lights were not working.
All I did to fix the problem was put in a second battery, and ensure the battery isolator switch (which was on the side of the engine bay near the top) was disengaged.
I also decided to wire my batteries in parallel (connect positive to positive, no need to connect negative terminals as they are both connected to ground) so that the main battery was connected to the alternator and would charge also. You can tell if your main battery is connected to the alternator by putting a voltmeter (there may be one in your dash) across your battery, if it shows about 14.5V then the alternator is connected. If it shows only 12V or less then the alternator is not connected or not working properly.

Warning lights stay on


Hi,

Brake light warning indicates possible low brake fluid in the reservoir;

Charge warning light indicates battery not charging which can be caused by defective alternator/regulator, slipping belt, corroded fusible link from alternator to battery B+ terminal.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
