A/t Light Flashing & Power Cut? Please Help

[Techo]

Hi Fellow wagoneers,

Whilst travelling from Toowoomba to Cootamundra yesterday( about 1000Km),my S2 would occasionally stutter, & on the bigger ones the A/T light would flash. It's never happened before & only seemed to happen in the heat of the day. It happened weather it was in tiptronic mode, steering wheel mode or in D, & only happened when it was cruzing, if it was on boost or not. Also my CD player would cut out at the same time.

Has this happened to anyone else or can anyone recommend a good Stagea/Skyline auto electrician/auto gearbox place in Canberra?

I want to get it fixed before i go back up & I'd love to meet & greet some of you southerners.

Thanx in advance,

Jeff

alternator or battery maybe? did u have air con on as well? sounds like the battery isnt holding charge or the alternator isnt charging the battery properly.

worth a try

cheers

I agree with Brad - I had these issues in my Corolla many years ago, stereo struggling to keep up, engine cutting out, headlights fading (I was driving at dusk), and stalling between gear changes and when slowing down for the lights (it would barely idle), etc.

I'd bet it's the alternator...

Sorry to dig up this old post, but this exact same thing happened to me today! It was a very warm day in sydney and happened 2-3 times on the motorway when i had the radio & AC on. A/T light would flash and sound on radio would cut in and out..

So is this def an alternator problem? If so; Does it need to be replaced or just repaired?

cheers

yeah i had similar thing tonight, s2 rwd doing a couple of donuts and mild launches in the wet,no real stress on it, cold night, A/T light comes on? is it a gearbox problem or just a warning light like the SLIP light with the traction control?

I agree with the other guys about the battery or alternator. Check your charge rate an do a load test on the battery. Also see if your battery terminals are tight.

I had this problem just before christmas... It was an easy fix though... with mine you would be just driving along and the power would cut, i.e stereo, A/T light, (sometimes engine) whenever you put a load on the system, eg. flashing your lights etc. The problem was in the positive battery terminal and the regulator/ resistor between the battery and the fuse box. It had shorted out and wasn't getting consistant power. Had a replacement made up and haven't had a problem ever since.... 2 weeks spent not driving the car because your worried its going to cut out you... $18.00 for them to replace it and its all sorted. Hope this helps you

If it is your alternator I have a VL one in my car now and it works fine, so there are cheap replacements out there, you don't need RB25DET specific parts.

Hey all had this exact issue happen just over the last two days. Series 2 stagea.

 

A/T light flashed and the car would drop power to stereo, clock and engine briefly like less than a second ... did this about 10 times on a long drive 

i pulled over turned car off and went to restart -  no power.

 

Took the leads off the battery and reconnected - started and drove off. 

Is this an issue with connectivity of the leads/terminals? They seemed clamped on pretty well. 

Battery may be old? Shouldn't be alternator should it? If it were alternator wouldn't it just eventually run down the battery and it start?

 

Will look over the following:

cracked leads

clean & refit terminals 

test voltage in battery and alternator 

if all else fails I'll look at the resistor mentioned above -

Get a multimeter and test. Probably a battery shop will test for you for free.
