Major Charging Issue Need Help

[jrmudder92]

Also it seams as if I have jinxed myself it seams like my problems are coming back :/

Contact cleaner (like DeOxiT) on the alternator sensor fuse on the battery post takes like 5 minutes tops to clean.

I always say if you are guessing at a solution, then knock the easy and cheap guesses out of the way first.

Can you tell me what’s done to yours? Is it stock? Is yours a land cruiser or Lexus? @jay3253

99 TLC stock, except for stereo, 2013 LC wheels, and no running boards. I just did the big 3 wiring (bigger positive battery cable, battery ground and engine ground).

I for sure thought it was one of my many electrical components but must be something different if yours is stock? Any new news?

I'm pulling stuff apart today and clean up anything I can see. Corrosion, dirt, tighten things up and put dielectric grease on everything exposed.

@jrmudder92 do you have a picture of the terminal block on the positive side of the battery. Both battery side and engine side. I think I misplaced a wire.

 

[jrmudder92]

Hope this help!

 

[jrmudder92]

Also I’ll be cleaning my tomorrow. It’s my day off so I’ll get that knocked out.

@jrmudder92 THANK YOU SO MUCH!!!!!

Note there is no alternator wire as it was replaced, rerouted and much bigger. it would be on the engine side of the terminal block.

Also, still have my charging issue!

This is what I found when I was cleaning (stereo shop did this, they didn't think they were bolted in place so the pliers did the trick!

Broken Fuse inside terminal

The Stereo shop broke the fuse now I have to talk to them about how and who is going to replace...

This was after cleaning and your very helpful pictures!

Angle one of the engine side of terminal

This is what I hope the wires are supposed to look like on the engine side, or the side away...

Angle one of battery side of terminal

Well damn I was really hoping that would solve or help it. Hmm... back to the drawing board!

My problem was that little 7.5a Alt-S Fuse. The fuse was fine and my connections looked fine. But after DeOxIt the fuse holder clips and reinserting the same fuse, my alternator has been putting out a rock steady 14v.

I never touched the other fuses, the wires or the bolts.

I’m not sure if it’s as good but I used crc battery cleaner on that fuse and battery terminals. Even new grease on that fuse still the same thing...

 

[jay3253]

Degreased, cleaned, check continuity on fuse and terminal block, regreased reinstalled still not charging correctly.

I’ve gotten where it can stay at 13.5 sometimes above. Just depends on what I’m running. But when it first starts for the day it’s doing like 14ish for about 10 minutes then back down.

I'm in the same boat. But once it warms up I only get 11.2v or so until it dies. Then need to charge the battery overnight.

We can't be the only 2 can we?

Do you all have Toyota OEM or Toyota Refurbished Alternators? Not an alternator sold at a Parts House or eBay.

The only time that I have ever seen a heat problem was with an overdriven alternator that was sold as a high output alternator or an alternator that was bad.

 

[jay3253]

All my alternators have been OEM new or referbished.

 

[jrmudder92]

Both mine were refurbished. They have discontinued new ones. Right now I’m having better luck with a new one that I bought off eBay. Then a reman one from Toyota.
