Glad you didn't get stranded. Have you looked into replacing the alternator brush? I know that is a thing in the 80's, not sure if it is a serviceable part on the 100's.Maybe this thread should be called "What did you fix on your truck this week?". We did a round trip to Charlotte on Saturday in the LX470 with no trouble. Then on Sunday morning after that torrential downpour I noticed the "Discharge warning light" come on.
At first I figured that I had left a light on somehow and drained the battery. But after driving around for awhile it didn't go away. The voltage gauge wasn't plummeting but it didn't look where it should be. A quick stop at O'Reilly confirmed that the alternator wasn't putting out what it should be.
I was impressed with Toyota engineering and/or my newish Interstate battery for getting us 20 miles home without a hitch. On Monday I sourced a new reman Denso alternator from the local dealer (didn't want to wait days for online). Our Upstate Cruisers discount is still in full effect at Ralph Hayes but they did not have one in stock. Toyota of Greenville did and helped me out on price when I asked about UC discount too.
The new alternator went in without a hitch, but when I went to plug in the sensor wires, I realized the plug tab was broken. In fact the whole plug was a brittle mess which made it easy to dissect it and install a new clip. But I had to wait another day while the local dealer ordered one. Part number 90980-11349 if it happens to you. I guess 16 years of heat dried out the old one.
I continue to be impressed by this truck, it gave plenty of warning. (The vehicles of my childhood always just left us stranded!). Perhaps more importantly, I was able to quickly find abundant info on MUD which made the fix quick and easy.

Sometimes you just need it now.Yes I thought about trying that. I believe they can be replaced on the 100 too. But I kinda wanted new bearings and regulator too.
I also thought about taking it to Dean's Alternator (near Trollhole's) to have them rebuild it.
But I was stuck ferrying the family around and just wanted to get the LX back on the road quickly, so I just decided to put a whole unit in.
I picked the Toyota OEM (Denso reman) hoping I'll get another 185K out of it. As opposed to the aftermarket alternators the auto part stores are selling.
