MFA--(lost)

i need help please..

just bought a G.T.I,not been used for 12 months.went to collect and the battery was all but dead but the digital readings on the dash were working,temp,clock etc changed the battery vroom vroom no problem, except digital readings all in a muddle  :? –nothing readable and no change when the end of the wiper stalk is pressed or on trip 2.

Any help would be fantastic,thanks in advance,Lee

Charge the battery up or buy a new one (the GSF battery is good quality and cost about 30 quid) and the MFA display will work ok, also check the alternator.

cheers lhasa,but its a new battery!!.alternator seems ok but how do i check for sure?

disconnect the battery and connect it again,putting the earth lead on first :wink:  

neil.

Have you taken the fuse out and then put it back in again....sometimes gives it a reset and works then.

riley, thanx.
did that no different…..

tom,which fuse is it as i do not understand any of the wiring diagrams.doh :dontknow:

just to update the digi thing is staying on with no keys in ignition,it just flashes everything that could be shown at once i.e 8888^><,hope you know what i mean.
what are the two little buttons for either side of reader?

  thanks for helping guys
         regards  Lee

The little buttons are for setting the clock.

try again m8,it will get it right unless the digi display is past it.

its just luck of the draw connecting the battery up,weather the display works correctly or not.

best to have a m8 connecting up while you watch.

leave it disconnected for a bit before trying again.

pulling out the fuse just has the same effect.

It could be damp inside due to lack of use. When I have not used my Mk1 for the winter and start to use it again and got o reconnect the battery, all the warning lights came on!  With a bit of use it cleared itself.

Also check to make sure you have an earth lead that connects to the right hand side of the head. It is on one of the nuts that secure the rocker cover on. That earth is for the MFA display, if it's not there or a bad connection, theres your problem.

right,ive cleaned everthing-earth wire to rocker cover,battery connections etc etc.at the last count we re-connected the battery - then + 87 times.each time gettig various different readings non of which made any sense at all.
 so,we then changed the clocks which were checked b 4 removal and they dont work either,so i guess ive got a problem somewhere but where  :dontknow: .

is the battery right? it is brand new and has 45 a/h on it,should it be 54 or 63 a/h?been thru haynes it doesnt specify exactly so will check with V.A.G tomorrow.

with all the cleaning my engine + bay are looking pretty dazzling,so not a total let down.

cheers again for all yer help, Lee   :wink:

36 Amp hours is standard (at least for the 1.6). 45 Amp hours is fine. But it makes no difference to getting your MFA to work.

Cheers

are there any other symptoms m8?

do the lights or anything affect the dials or lighting?
any water temp or oil lights flashing?

sounds like a wiring problem now,if youve tried other clocks…

neil.

IT'S A MIRACLE!!!

 Guys,just got home and thought i'd take her out for an airing……..but whats this?

the time is up on the M.F.A  :?

everything else is working too,every switch lights up,all mfa functions work.perhaps we didnt give it enough time to settle when doing the battery leads,which were extremely lagged in grease as was the earth to the rocker cover now they just have a smearing of petroleum jelly on them as do all the other connections under the bonnet.

I'm now very happy, i think the old girl just wanted some attention paid to her after being left for over a year(the wife says she knows the feeling) what does she mean???? :wink:


 Thanks to everybody for their input,(it's all helpful when you don't know what yer doin')
                  Regards   Lee  :y:

good to hear m8  

wish mine would fix them selves!
