voltage meter go up n down

[z_boi 0]

Hi guys, I dont know what my problem is but i was hoping you guys can tell me. my voltage meter isnt very steady and goes up and down alot. There were a few times where my car didnt even crank. when i turn the key to the on position, the voltage meter went all the way down. but then i checked my battery clamps and they were kinda lose then i tightened them and i haven had the starting problem yet.

Im not sure if that was it, but my meter is still jumping around. Could it the VR or the resenator?

Resonation is a sound thing, I think you mean regulator. The voltage should raise when you raise the RPMs past a certain point, probably around 1000-1500 or so is good enough to test.

Is your battery dying on you after driving with lights on or ? What are the symptoms you have that you are troubleshooting the alternator in other words.

the car runs fine. although i am finding that theres a lot needed to be fixed. and the rpms do not affect the voltage.
