Hi All
this is probably the same problem
that Madenpold is haveing as it is a
different engine i will start a new post
mine is the 2.9 24valve cosworth which as
a different alternator i believe
And yes i have the battery cover fitted
now my prob started last year with the
dancing needles so in Nov i changed the battery
when i was at the Midands meet beginning of
jan my onboard reading was only 11.4 even with engine
on,
so poss a faulty alternator, located
one out of a scrappy,took it to a local rotating auto electric cmpny who said it works ok,charges £4.00 to test
so this evening fitted it,now when ever the revs go above 1000 the battery light comes on and its still
only showing 11.4 on the onboard comp.
what else can i now change

Ren,
could it be a slipping belt? If the speed increases too much, the belt could be slipping and not turning the alternator
Just a thought, I've had this on a few previous cars so might be worth checking the belt tensioners

The belt are auto tensioned on the scorpio on all models but I would suspect the alternator... if the light comes on with revs suggests a dogey diode in the rectifier but I may be wrong... thats where I would be looking first....Also check the connections to the alternator and the battery earth....

hi ren if your new to you alt checked out ok then i would start going to each earth point and clean them (battery,engine strap and alternator conections so on )
as it sounds like resistance due to corrosion in the charging circut

Thanks
On checking the connections on the
Alternator haveing them taken off
and put back on it seems this may
have been the problem,instrument
panel now correct,battery light on when
key turned, off when engine started,
13.5 showing onboard comp,this to be
expected as battery not fully charged
at time, only useing it for checking each
time after doing something.
Thanks again
Ren
