Car starts then turns off

[fuzionz]

New ignition switch on my mate just fitted it.

after 10mins the gauges start to dim out and goes back to normal.

i turned the car off.

turned the car to II and it looked like it had a flat battery, because gauges were very dim.

then I turned car off

Turned car on again then it gauges were normal. but car still turned off

Sounds like an electrical problem some where, anyone got any ideas???

So the problem with the ignition is gone now? But the cluster lights start to dim after 10 mins? Is that when the fans start to kick in? Check your ground wires? Do you have a voltage meter?
If so, sus out the voltage it is when the lights go dim.
