what do you mean by pull the cable? pull it off? or just nudge it?

 

how bout I just come over and help you screw it up a little bit more

 

On most cars that is a normal occurance since what you are doing is removing the ground.

 

but it shouldnt my shop teacher says if i do that then im running off of the bat and not the alt. and if i gas it the current reading doesnt move it stays at 12

 

If I understand that correctly, how could it be running off the batt if you just pulled the cable off? What are you trying to do, anyhow?

 

you pull the positive off not the ground...

 

ok the pos not the neg ok. well lets see if it still runs.

 

that still doesnt solve the problem i have with it not fluctuating when i gas it.

 

pulled the positive off and guess what it died

 

what do you mean not fluctuating? like not accelerating

 

how bout if you leave it running with the cables on does it eventually die or stay running? you have the other connector that goes into the side of the alt connected still and the cable that goes to the post on the back of the alt?

 

when i accelerate the or give the mtr gas. the voltage reading stays the same. and yes the engine stays running if i dont disconnect the cables.

 

how many volts is it reading and how long will it stay running?

 

12 and until the bat dies

 

its all good my uncle and my dad fixed it for me
