Hi all,

i fitted a brand new battery this morning, turned her over and all was fine.

not 30 minutes later i tried to start it again and it was flat.....clutch started it and drove off. about 10 minutes down the road the car started to choke....the revs began to bounce and within 30 seconds the car cut out.....i pulled over and tried to crank it.....flat.

i pulled out a charged battery and jumped started it.....disconnected the jumper.....and fine for 20 seconds......then revs started to bounce again....then cut out again....

i swapped the batteries....and the she started fine and ran ok......i then disconnected the battery as i didnt want it to drain again......i was then able to drive the car for 10 minutes home....

i noticed on the way home that the battery light in the dash was on.....firstly what does that light mean? and what do you think i am faced with?

im thinking alternator is cactus....but why?? nothing has changed since i drove it last....

also i just changed front bar....could the fog lights, even tho they are visibly off, somehow be on and sucking power? nothing else has changed....

list of things i need answered...

1. what does the battery light in dash mean?

2. could it be my alternator?

3. how hard is it to change an alternator?

4. fog lights?

thanks guys!!

Problem resolved. The wire from the alternator to the dash failed. Can't believe that's all it was. Cars working like a dream. Thanks everyone!
