Electrical Problem - Nissan Sentra 94

[MarkStert]

Hi, Yesterday, my nissan sentra 1994 (245000km) started to be weird.The only way I could get power on the wheels was to slightly pressthe gas pedal. If I pressed more than that, the motor wanted to dieand the car was able to run at idle speed. It was not possible to gomore that 5mph.

By turning the headlight off, I gained lots of power so it was possible toshift speeds. But 5 mins later, the motor started to do the same butheadlight off. I got stuck. It was impossible to start the car. The staterdid not wanted to do anything. So I thought my battery was dead froma bad alternator.

Somebody came to boost my car and started instantly. The cables wason my car for like 10 seconds. I drove my car with lights turned off tomy house and didn't have any problem.

This morning, the car started by itself easily. I measured 12.5V on thebattery and 14.0v car running. So everything looks good now. Anybodyhave any clue what's wrong with my car?

I had to replace my meter fuse recently.

Regards,
