3 WARNING LIGHTS ON

5">

All three is probably an alternator/ no charge problem. The dash does it's "check bulbs on turnon" thing if charging stops. Suspect a loose connection or sticky/worn brushes.

Have a similar problem as you described but I also have the lights-on
warning signal on permanently with the ignition and lights off - the only
remedy is to leave the door open slightly (I suspect there is a short
somewhere but cant find it) It broke down on the way from cornwall last
week, booster charge got me back to dorset but the problem then developed
into three warning lights on also. Another problem that happened was the
the fast idle wouldnt cut out on choke (I have an auto) this is
electrically activated which makes me suspect a short rather than the
alternator. Broke down this morning from dorset to london (the car not me)
with a complete electrical failure. The recovery guy gave another boost
and checked the alternator which he said was delivering a charge, this is a
reason why I suspect a short, the car ran ok for about 15mins then the 3
lights appeared again. Recovery all the way from Ringwood to London. -
Brilliant fuel economy!!
Checked the earth to engine terminals ok but couldnt locate the body to
earth terminal I think its a short under the dash somewhere or possibly the
ignition switch. Hope you get some clues from these symptoms. If you find
out what the problem is could you let me know. Thanks. - (#839) David Miller, 20 Aug 01

I have had the exact same problem which has now been cured, it is caused by the regulator in the alternator. The spacecruiser is now back to her reliable old self. - (#841) colin back, 20 Aug 01

does any one know what causes OIL-WATER-BAT light to go on at the same time. sometimes does not come on for 10 mins. Toyota space cruiser 2.0 GL.
Seems to running OK ? - (#842) colin back, 20 Aug 01

hello Steve not sure if the 1st message got through.The three lights are caused by the regulators being u/s in the alternator.It is a relatively inexpensive job. - (#843) colin back, 20 Aug 01

thanks colin
sorry for the delay in reading these helpful replies about the lights. I have been given a price from toyota of 180 quid to replace the alternater. What do you mean by inexpensive, is it a regulator kit ?

Thanks for the info
Did you replace the alternator or can you just replace the regulator alone?
I have cleaned up these terminals on the alternator and worked it for a short while.
This is obviously the problem I'll take it off completely and have a proper look at the connectors - (#862) Ed Ben, 22 Aug 01

Yes you can just by the regulator,however I purchased a reconditioned alternator for £50.
Glad to help. - (#886) colin back, 24 Aug 01

Hello Steve the regulator was £15 Regards Colin - (#1113) colin back, 21 Sep 01


I have had problems with the three lights, battery, oil and water being alight on the dash board.To cut a long story short, the alternator/ regulator wasn't switching off the current and my battery boiled dry. We changed the alternator and the battery and now the main lights, indicators and brake lights dont work. I have an engine repair manual but it doesn't show the electrical wiring diagrams. Has anyone got a copy they can fax me or can anyone give us a detailed guide as to what to do. We have had all the dash out. The fuses are all working. It's a mystery! - (#888) kim.boswell, 25 Aug 01

Check the fuseable links- either beside the battery or under the drivers seat - (#889) David Miller, 25 Aug 01

I had this problem on my 1990 SpaceCruiser. I figured it must be a wiring problem. On the live battery terminal, there are 2 (I think) connections other than the main one. One of these was loose. I reconnected these wires and the problem disappeared.
