2003 350z
issue: at times when i start my car, i turn the key and all power is lost. i have to go pop my hood and wiggle the positive terminal and then power is restored. My negative terminal is tight, my positive one is a bit loose but i bought a brand new positive terminal connector and it still is loose. The battery is correct size for 350z.

if i tighten the positive terminal all the way it still won't be snug like the negitive terminal.

 

check again...

 

when i read ur comment i went to go check again. but i cannot tighten down any more its still loose. should i check one more time?

 

How old is the battery? Is the positive terminal worn down to a smaller diameter?

 

Go to pep boys and get the correct terminal/cable. Worse case, shim the terminal with lead shims.

If you can move the terminal, it's the wrong one.

 

im going to go out on a limp and say, your connector broke or you have the wrong size connector. you can run to autozone and get oem connector for like 5 bucks.

battery is 3 years old. i think what you said about the smaller diameter is correct. but shouldn't a battery that fits the Z fit without any issue

good deal i think im gunna get that

 

yessir. but i think the diameter of the terminal is too small. im gunna grab a shim
