Battery light/no clocks

[tobyk]

Alright

Was messing about under the bonnet of my mates VTR tonight, it's a Y reg, has Mk2 headlights and a 3 plug ECU.

Basically I had my multimeter leads in wrong and when checking voltage across the battery there was a spark. Checked the car and it started fine so thought nothing of it.

A few hours later, went to start it and it struggles to start without throttle, there is no lights inside at all, no clocks, nothing but the battery light. Only 9v across the battery when it's running. Apparently there was smoke from the ECU area too.

Any ideas? As simple as being definitely the ECU? If so, what's the script here? Can I simply replace it?

Cheers

Would it be worth trying an alternator? Maybe voltage regulator shorted? Just seems odd there was apparently smoke around the ECU area

Multimeter leads wouldn't cause any problems if put on the wrong way, any chance you've touched something from the positive terminal to earth/car body?

Check your voltage regulator on the alternator mate.........

They would, trust me. I don't mean positive on negative and vice versa, I mean I had my multimeter set up for continuity which means it shorted everything in the car.

New ECU sorted it people, cheers anyway. My first thought was the voltage regulator on the alternator, but it wasn't.
