HI,
I have a 2002 blazer with the 4.3 it stalled today and there was no power to the engine?
Tow it home and it started up with a jump! If i hit the brakes the dash lights faker and it whats to stall out?
Could someone please help me finger this out!
Thank you for you time.

 

What do you mean no power to the engine?

If you started it with a jump then I presume that your battery was dead? What is the voltage at rest and when the truck is running?

What happens to the dash lights when you hit the brakes? Does the same thing happen when you turn on the headlights?

Have the battery or alternator been replaced?

Battery is new! Drove it 15 miles was charging battery all the way when it stall out no power to restart ?
Battery at the stall out was still charged up, but could not get the starter or lights to work no power with the key on!
Unhook the battery before tow, after towed home had to jump battery! If i hit the brakes the dash lights faker and it whats to stall out?
Thank you for you time.

 

Sounds like the alternator is not working; is the belt on the alternator? Do you have a voltmeter? Need to put voltmeter across battery terminals when engine is running to measure alternator output voltage; voltage should be 13.6 to 14.3 Vdc or so, if less, then engine is running off of battery, which drains the battery in a short time.
If it is the alternator, good news is that they are easy to change-out.

alternator output voltage is 14.3, headlight also faker when on!
Thank you for you time.

 

Please provide the voltages that I asked for.

Why did you need a new battery?

Battery is one year old!
Alternator output voltage is at 14.3!
