who knows what i'd do with a modern cars' electrics!

 

I realise it's a fiesta thing, but i figured the charging setup is probably common across the board

 

any help with this would be hugely appreciated

Check the earth straps to the engine from the bulkhead/inner wing and also the one from the battery -ve terminal to the body. Actually take them off and clean the area around the bolt/screwhole with sandpaper and also clean up the connectors as well.

yeh cheers mate i've been on a bit of a earth cleaning rampage but no luck so far

what age fiesta is it? what dash is fitted? petrol or diesel?

check out the regulator of the alternator

[bortaf]

Change the alt, it's the diode pack, all alts will step up to 14V over about 2500 revs but the diode pack should be controling it ~(and the dash light) at all revs over 1000 ish (tis why you sometime have to give a freshly started engine a wee rev to get the light out).

sorted it - all running well wanna know?????????

 

 

 

i measured the volts to the bulb from alternator signal wire - fine. volts to the other side (so the main system) 6V! traced the wire back to it's fuse. measured good volts one side of the fuse - 6V the other! looked at the fuse and it just needed a rub as it had 'furred' up (i guess due to the electron flow over time.

 

So i've checked all the earths, battery, alternator removed & brushes checked, dash removed, opened wiring loom behind the dash, and nearly bought an alternator

 

so, new matra for me - "check the fuses first!"

 

 

cheers all those that gave help!
