Broke down on the m25 whilst it pissed it down this morn. found out lead 2 was arcing massively at the cap. 1x new lead later, car starts juddering a bit, had a look under thwe bonnet and there are now a small blueish spark at the plug end of lead 3 and the battery led on the dash is flickering real dimmley when the car idles. Any ideas?
-
You need a full set of new leads and check the alternator belt is tensioned correctly.

Also a new cap and rotor arm.

Can anyone offer insight into whats creating the constant blue spark (at the very bottom of the lead / where the rubber end meets the head)
-
It'll be the rubber perished on the lead and the lead arcing out onto the block.

That is pathetic, they are only about 10 months / 8,000 miles old!

I've had this happen with a brand new set of cheap leads from GSF and have found the cheaper leads to be generally rubbish on 8v's. I now only buy pukka OEM quality leads and they last much better.

I think these may have come from GSF (look abit like oem with the metal jacket round the rubber at the plug end, but cheapy rubber at the cap end).
Ordered a set (beru) from vwspares this morn on recommendation of this forum. Worth a punt at £20 for 4.
Do you remember how much you paid for the OEM?
-
The beru ones are OEM quality and they're the ones I run on my track car (and on the Rado when I had it).

The battery light flickering @ idle could be the voltage regulator in the alternator, mine does this and I should sort it out really...

Light goes off when engine revs >2000rpm. Gave it a whiz round the block and it stopped, will have to see if it does it tomorrow. Does yours do this?
Was thinking it could be a dodgy connection from the alternator to the battery.

undo the 2 screws on the back of the alt that hold the bush pack on. check the 2 bushes have meat on and are about the same length, then clean up all the electrical mating surfaces. if you look in the hole you'll note there are 2 prongs, these contact a metal part of the bush pack. had a similar issue on a mates 16v, turned out this mating face was covered in rust! cleaned it all up and bit of grease, fixed!
