hj61 Carwash = All dash lights lit up like a Christmas Tree! (1 Viewer)

[lisponger]

I recently took my HJ61 to a local DIY car wash and sprayed all the road grime, salt, and mud then proceeded to drive away.

Just minutes after all my dash lights and shifter lights including AT Oil light were illuminated.

Battery light, turbo, overboost light, AT high temp light all are illuminated.

Steps I took:

I disconnected both batteries - No difference.

I trickle charged each one - No difference.

I went through the entire interior and under hood fuse box - Only the "Charge" fuse would make the lights go out when I pulled it. BUT when I inserted it back all the lights were still illuminated.

Obviously I sprayed down some sensor to make all these lights come on...

Any clue where I should look, adjust, or clean next?

Besides that the truck is running absolutely fine.

Water in the fuse block would be an obvious place to start. If the fuse block is wet, blast it with compressed air. Did you wash under the hood?

I'll go check that out.

I sprayed the hood down and the wheel wells. Water def got in somewhere!

You mean the main fuse block correct? The one on the drivers side?(RHD)

A bad B pole alternator connection can cause a defective charge light relay which will give you the christmas tree
symptoms.Same with worn down alternator brushes.

Clean up alternator connections!

I had a 85 4runner with the same problem. It was fine after I replaced the alternator. Your results may vary though.
