Keep getting 4 lights appear on my 94 na j spec. The battery symbol the one to the right of it the orange exclamation mark and the oil light. There are no other obvious problems like lack of power electrical or mechanical. They do seem to go off under harsh acceleration but then come on again a few minutes later. Any ideas what this could be?

Definitely alternator symptoms, except you say you've changed it out already. The lights I had when mine went were oil level (yellow light) first, (went out wen revs increased). Then catalyst temperature, then ABS warning and last of all the actual alternator / battery light.

Cheers guys, got a feeling it might be the crank pulley. Had the car 18 months and it's always had a strange noise on tickover like a skimming noise. Seems to be coming from this area, goes when revs are raised so gonna change it anyway. Hopefully it will sort it.

Well turns out my spare battery was knackered so I went and bought a volt meter. With everything on it read 11.12. With everything turned off it read 11.48. This was on tickover. I'm assuming I need a new battery?

 

 

Would appear so... Where did you measure from? I had problems with poor connections in the past that appeared to be battery but was actually a poor connection...

Top of battery terminals so won't be poor connections. Raised idle speed and it dropped to 11.0

Recently changed the alternator, was fine for couple of weeks but it was quite oily and ive noticed an oil leak around the distributor which looks like its dripping straight into the 3 pin plug on top of the alternator. Tried to wipe it out but hasnt made any difference.
