Dodgy battery or Dodgy Electrics?

My 1994 Renault Clio behaved oddly this evening, whilst driving home. Sat in traffic for about 10 minutes my battery light came on. So I pulled over in the petrol station [thinking back to my FTO experience, and that if im broken down Im going to do it where I can at least eat something], and turned the engine off for a minute - and it started fine - but the battery light was still on.

 

So off I go, thinking Im nearly home please please please don't die

 

I drove about three miles along the road, constant traffic at about 25mph - the battery light still on.

 

As soon as I could I planted my foot dropped it into second, and tootled along the road as quickly as the poor little engine allowed and the stupid light went off. That was it, it disappeared?

 

I should note that twice now I have needed a jump start as I left the lights on once and the radio on another time. :D

 

What do you think? Worth taking it to ATS for a battery check?

switch ignition on if you have a battery light then its the alternator. if there is no battery light with ignition on and engine not running, then i;ll check earth point first. but its still more than likely a blown diode in the alternator.

Okay tried this turned the ignition on [engine off], the battery light is on [so are the other lights], but turn the engine on and the light goes out like you would expect. :)

 

If you have a multimeter, check the voltage between the battery terminals with the engine running.

 

Im going to run it down to ATS tomorrow. See what they say

 

What is it with me and bleeding alternators. :shrug:

I would say it sounds like the brushes on the Alternator are ready for replacing, was it a dim light when you where in traffic or full on?

 

it was flickering depending on how fast I was going. :D

 

I can get a refurbed alternater for £60 so thats not as bad I first thought. :)

 

Anyone know how hard these are to change?

 

What sort of time scales before it does an FTO on me, any ideas? :)

 

Thanks guys.................people should not let me near their cars ...... I must have some bizarre power where I can absorb the power from Alternators. :D
