Generator connector Question, 1995 Tacoma (solved)

I recently replaced my generator connector plug (because it was broken.) After driving the truck for a few days the battery wasn’t charging. I then noticed one of the (three) wires had a short. I bought three replacement wires and soldered them in. I thought the wires going into the connector plug went in this order; yellow, red and white, from the top, left to right. I have the service manual but can’t find a wiring diagram.

My alternator and battery are new but my battery light, on the dash, stays on.

When I switch the yellow and white wires the battery light is off, even in the auxiliary position.

I’m getting 14+ volts from the battery when the truck is running, no matter witch way the (yellow and white) wires are positioned.

Any help would be appreciated...

 

hope this helps...

 

So, if I’m reading this right; yellow is 1, red is 2 and white is 3?

 

If so, this is how I have it and the battery light still stays on... but everything is new... I soldered all connections and put heat shrink tubing on the exposed solder connections.

Could I have a bad (new) alternator?

Edit: the alternator is producing 14+ volts..

 

I am confused the battery was not charging but your alternator is putting out 14+ volts?

Just what voltage is the alternator putting out ??

The light also comes on during over voltage conditions

Are you reading this with a Meter ??

If you had a short do you have open circuit protection or melted burnt wires ??

Was this a brand new plug or used not uncommon to have used ones corrode .

 

Double check wiring but, also check your fuse in the box under the hood, it should be a 7.5A fuse labeled Alternator. Given that your battery light is on it’s probably not this but worth looking as part of troubleshooting.

 

OP have you managed to Figure this out??

 

I did. I rechecked the wiring and it was correct.

When fooling with the wires I didn’t disconnect my battery (d’oh) and blew the fuse.

I know I might ask some lame questions but, I do appreciate all the help guys! Happy New Year!

 

That is how you learn things We all had to start someplace

 

You silly Falkor! Just kidding. Glad you got it fixed.

 

You have a fuse labeled Alternator? I've looked at the fuse block, next to the battery, and didn't see a fuse with that label. I guess I need to look again. My battery light won't go off either.

 

It’s actually labeled “Alt-S” for alternator sense, located in fuse box under the hood. This is the feedback to the alternator of battery voltage so the regulator in the alternator can adjust voltage up/down. Check it, but also consider replacing alternator brushes if your battery light is on.

 

I found it...the terminals were a little "crusty" so I cleaned them up and replaced the fuse. The light is still on. Bummer.

 

check your alternator brushes, a replacement is under $20 and quite easy to replace once you remove the alternator.

 

The alternator is less than 2 weeks old.

 

Battery good? Terminals good?

 

Just why was the Alternator replaced??

Was the battery charged before you attempted to start your vehicle .

When did the light come back on?/

Have you checked the voltage at the battery the light will light on a over voltage condition as well as low voltage .

Does not mean it has not failed already depending just who the rebuilder is.

break out the Meter $20.00 will get you one to do what you need to.

 

I didn't think the charging system monitored the battery. But to answer your question - terminals were cleaned; battery will charge up to about 75% (it's old - but not as old as me)
