dash lights stay on

[erik spain]

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

for everybody .

Merry xmas to you too!

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

 

[erik spain]

Hi Karl ,

when runs it tells me 12 v

 

[erik spain]

on both batteries the same

 

[karl2000]

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.

ok thanks so far far ,

i will test tomorrow with multimeter for exact voltage charging and come back over here .

I thought that suggested a poor earth or the plug in the back of the alternator loose or full of muck?? Worth checking?

 

[erik spain]

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 ?

 

[karl2000]

Yes

Ok , thanks Karl ,

Some place that you recommend to check first .

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.

 

[erik spain]

thanks , will try tomorrow .
let you know .

Hi guys ,

Sorry but was busy with other things .

Checked really all I think!!!
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.
