voltage drop when starting
 
83 c30 454

when i try to start the voltage drops all the way down , so i replaced the starter and it is still happening, i need some advice on what is happening and how to fix it

by voltage drop do you mean you actually kill the battery when cranking the engine?.........If thats the case it sounds like you need to check your Alternator and have the battery replaced...............other wise I would check all wiring to the starter and make sure they are all clean and tight (I would do this anyway)

yeah as soon as i turn the key the voltage drops to the red, let go and goes back to normal
