Hi LC fans ,

got a series 100 automatic from 2002 with quiet some extras like winch , lights , compressor for suspension , etc .
all works fine , runs great but a lot of dash lights stay on when the beast runs .
some fans experienced this before ?

regards Erik
these stay on , and also can't find anything with my Auto diagnostic .
can do quiet some things with cars but electric is not my thing .
so hope to get some advices from you guys over here .

and to forget
:text-merryxmas: for everybody .

Merry xmas to you too!

First of all, when the engine is running whats the voltage at the battery?

If the engine is running it sounds like rhe alternator isnt charging the battery. Is the belt on ok? If you rev it up a bit any change in the voltage?
All the lights on older Toyotas usually means some alternator/charging/voltage problems. On newer ones it can mean the is a fault code somewhere - ecu, abs etc. and needs scanning.
Hi guys ,

Tested the voltage charging on left battery gives 14.44 volt and right battery 14.48 volts .
got two new 95 ah 830 installed also .

is it still possible that there is a bad earth connection ?
Check that plug on the back of the alternator. Wiggle it while someone watches the dash.. give it a good clean inside with contact cleaner.
Hi guys ,

Sorry but was busy with other things .

Checked really all I think:confusion-confused:!!!
Also plug at the back of alternator , took out the fuses connect the earth cables again .
Should it be possible the dash print is broken or so .
Most common:
  • Alternator plug
  • Changed/leaking windshield - water on ECU or junction block under dash.
  • Ground strap for engine (at engine mount and rear of top). Same for batteries.
Ok thanks ,

Another things to check ,
happy with all of you on this forum .
