ZT190 2.5V6 Flashing lights!!!!!

[loupus666]

Morning everyone, I experienced something strange last light..........no not that! Whilst driving home through the Essex countryside I noticed that the dash illumination was flashing. Being a cold damp night I had everything switched on ie: heater blower, a/c & heated rear window.......however when I switched the heater fan off the pulsating dash illumination stopped

Any ideas?

[Rich]

Hi, was it clearly flashing, like on and off, or was it more sort of pulsating (like dimming a bit)?

[Alex30013k]

Has it started to day?

:lol:

[loupus666]

More pulsating than flashing......am off out soon I hope!

[loupus666]

started fine!!!!!!!!!!!

[GreyGhost]

started fine!!!!!!!!!!!

Glad to hear that, any recurrence of the pulsating dash lights?

[loupus666]

Will look later when it gets dark

[loupus666]

Wierd! all seems to be ok now.....but if anyone has heard of this problem please let me know because it`s really annoying when trying to concentrate on the bendy bits!

[Simon]

Usually lights going haywire can be a sign of a low battery or signs that the ECU has got wet. This will lead me to ask the obvious: Have you checked your battery and plenums recently?

[rdholmes]

Also the obvious - did it pulsate as you rev'd and braked? I'd guess dicky battery.

[loupus666]

.........plenum clear battery seems good......pulsated all the time not just when braking or accelerating!

Have you tried turning your dashboard lights up or down with the dimmer control? Does it still do it when its brighter or dimmer?

good point ken i had that with my 1st one the switch must have had some dust in

that or turn the bass down a bit:) ;)

[loupus666]

Right, heres the update ......This time I drove along with the window down & the bass (radio) turned off ..... & it`s all the lights pulsating not just the dash illumination.......dimmer control has been twiddlled, revs altered......but now with a bit of peace & quiet I can hear an intermitent clicking (sounds like electrical contacts tripping on & off in the engine bay)....the plot thickens!
Mark

[Chilljohn]

sounds like a dying batt or a diky alternator

when did you have your batt changed last ?

[loupus666]

Only recently bought the car & hav`nt checked the battery ....but there seems to be none of the usual duff battery stuff....like not starting & stuff!!!

[Chilljohn]

the zt/75 are very very funny about thre batts the slighest defect in them and the car plays silly buggers the 1st thing id try is a new batt or if your your usufll with your dash you can see if your alt is kicking out the right voltage by follow ing this

you want option 9

if you get it showing somehtin at 2ng ig no engine thats the batts voltage it will change as you turn lights etc on , then start the car and try it and let us know the reading , it might help
any thing high 10s or below i beleive will cause the car to get a bit grumpy

Whoa!!!!! do all zt`s have on board diagnostics? is this all possible without some external computer?

Mark

yup all done via the dash :) all 75s and zts have this go have a play and have fun number 2 is rather good

[loupus666]

Thanks Chilljohn, I`ll try it tommorow....p/s I havn`t got a trip computer so is this done just via the speedo trip reset?
Mark

[Chilljohn]

yup doesnt involve the trip computer at all and in a sense it gives you one lol

Don`t know if I`m reading it right but on option 9 of OBD, I have (119 engine not running)
& (142 engine running) how does that sound?

[Chilljohn]

that 11.9v and 14.2 id still be tempted to try a new batt

[loupus666]

Heres the update.....batt indicator green when tapped! the clicking I heard before is the fan motor on the higher speed!

[loupus666]

Hello......don`t know if anyones still following this but heres another update,
I`ve just fitted a brand new battery from my local x-part dealer....£58....not bad I thought!!!!!!!!!! all the lights are still pulsating....any more ideas?

[Chilljohn]

id get the alternator tested next see if it is putting out a steady voltage !

[Keith]

I think you have a duff rad fan motor and it is only kicking in at the high speed these draw a lot of current and will cause the effect you are describing if constantly being turned on and off based on cooling demand

You have not included the engine type in you thread title like what I expect everyone to do here when asking for help ;)

Sorry I didn`t quote the engine type in the thread !!!!! but will do next time
Thanks....it`s a zt190 2.5 kv6

[Keith]

Ah in that case have you checked you fan works?
For the V6 engine you need engine running and AC on Auto, or in this cold weather on Lo fan should be going constantly with one proviso read the last two paragraph here as the temp differential seems to increase as it gets colder outside hence why you may need to put yours on Lo
