I was parked on a lake having a romantic time w my cousin - smoking a cigar, when my 12 full size starting sending off alarms. Dash lit up like a Christmas tree. I like quickly shut her down. She wouldn’t restart. clicking like a bad battery. After exploring the positive cable was lose. I had tools but the nut wasn’t compressing the terminal. I used some mechanic wire to snug her on there. Still wouldn’t start. Passer by gave me a jump. She started right up. Off he goes. Car stalls out again. Seems to be an alternator but I just don’t know. I had her towed home. Put a new battery in here and drove her for two days (220 miles). Tonight on way home charging system fault came on dash. I gambled and decided not to pull over. I made it 16 miles to my house without trouble.

Upon looking under the hood, Cables seem to be secure. I was intending to purchase new cables or terminal ends and install this weekend. Using the Nav screen and diagnostic tool - battery is sitting just below 12v when at idle. Seems low.

How is do I go about diagnosing this ?

Cables ? A fuse. ? Someone said there is a charge controller ? Is it an alternator perhaps ? Any clue if there are any shop instructions on how to replace the generator on this ? Just did my LR3. Wasn’t the best. Wasn’t the worst.

Thanks again

 

I would leave what you do with your cousin out of the story... LOL

As for your charging issue, start with a fully charged battery so the vehicle will start on its own. Then, use a mutimeter to measure voltage directly at the battery. fully charged, you should be 12.5V or more.
Then start the vehicle. Once the engine stabilizes, the voltage should increase to 13.0V or higher. If voltage does not increase, the alternator is not charging.

Alternators do go bad and are easy to replace.

 

Well, I’ve pretty much arrived at the fact that my alternator is shot and woke up this morning with the intention of throwing a new one in. Got the car raised up and what I’m looking at seems daunting. There seems to be virtually no clearance to get this alternator out from the bottom - or any direction for that matter. I see now videos on how to do this for a 2012 full size. Does anyone have the workshop procedure ?

The bolts are not my issue. It’s what bees to be removed that I really need to understand.

Would appreciate it !
