80 Series Warning Lights all Stay on.

Possibly try giving your altenator a good clean out. Maybe even pull it out and strip it down and give it a birthday. It could be the connections to the alt also.
Hope this helps

Cheers

Richard, The alternator (er) theory may be correct as when my alternator went on the 60 series, the dash lit up like a Christmas tree, every warning light came on.

remove the plug near the altenator give it a good clean with a dewatering spray then spray with a light oil [ say a silicone based one] and refit should be ok safe driveing mal b

I have had similar problems with my 100s
It is a known problem

Dash Warning Lights

A common problem is that the dash warning lights come on suddenly. They may go off after a while, flicker every now and then or go off when the motor is revved. The problem often occurs after wading through a deep muddy bog.
The culprit is the alternator. Grit may become embedded under the alternator brushes and it stops charging. This brings all the dash lights on (that's one way to get your attention!). Or, the alternator is on its last legs and will need new brushes or a complete rebuild.

I said I was going to get back to the group regarding all the warning lights in the dashboard of my 91 model standard 80 coming on. The final outcome is that the alternator is ok but there is also a square type plug that fits into the rear of the alternator. This plug on closer inspection had moisture and dirt inside it. I cleaned it and gave it a spray with some WD40. Also the lead from the battery that connects to the alternator with an "eyelet" connector via a 12mm nut was found to be rusty/corrosive nut. A clean with a piece of sand paper and hopefully I have fixed the problem .

Richard,
mines going in to be fixed today, same thing, all dash lights on.
Mine is the alt overcharging, will let you know what the damage is & if it was brushes or a re build,

As above, clean the connections on the back of the alternator, and clean out the plug as well. It may take a few attempts but it will work. Grab some carby cleaner from an auto shop and use this to clean it. Tighten the connections in the plug with a small screwdriverer.
This has happened twice to me, on both an 80 and my current 100. Once you have cleaned it all, put lots of lanolin on it.

Good luck with it.

The same thing will happen when the brushes in the alternator wear out.
The worst thing is that you will not get any warning.
It happened to my Hilux on Easter Sunday in Renmark.
I was able to drive all the way to Port Augusta and had it fixed there.

Just letting you all know, I took it to an auto electrician and yes the Alternator was sad. The bit that looks like a heap of wires with multiply connections coming off it, was full of dirt and mud. The bloke reckons it has been like that for ages and is probably the original one so has done 300 000km. Anyway he reconditioned it and fixed up the solinoid for my Dual Battery set up new wiring etc and a new Deep Cycle battery too. Now all is good.

Some advice he gave was when you go through mud/dirty water, he recommended to thoroughly wash the Alternator with the hose when you get home. I didn't think you could get that much water into them but you can with no worries apparently.
