Alternator and Volt drops

[Habnixzuverliern]

Hi,

 

I need help, i guess i know the answer but just to be sure.

I have the problem, that if headlights on and i turn the wheel, my volt drops and sometimes it drops so low that the steering assist goes off. I also checked the voltage in idle and its around 12,x to 14,5 and its going up and down, all the time. Also the light is dimming, when i turn on the turning signal or hit the breaks.

 

I think it is the alternator but not 100% sure.

 

Happy to get some ideas.

 

Thanks

 

Pierre

Check, clean, change grounds. What year truck and how old is the battery?

Same as snowcamo said.  

 

Turns out mine was the alternator going out and so I replaced the 150amp with a new 170amp.  Been fine ever since.

Battery ground wire is changed, already.

I have a check lamp, which I used on the fuse box and the check lamp is also flickering, if I do the same on the battery terminals/cable no flickering.

Im gonna save you the future headache and cost now by saying this. Get a voltmeter and stop using that light. If your in the DFW I'd meetup with you some parts of the electrical parts dont like being grounded at all.

Yes, I have a Voltmeter but didn’t had it to hand. So I used what I have in the car. I also want to check the voltage without belt and see if there is also a problem, but didn’t had a chance so far.
