My 2002 stock battery finally died. I stopped at Auto Zone on my way home that morning from work and they guy gave me a battery that was smaller than the one I had. It also had smaller terminals. I could not get the connections tight enough on the negative, so I went back in and asked if he gave me the right battery. He said yes and came out to help me install the battery because I must have been an idiot. He was also unable to get the connections tight enough, or the bracket down onto the battery and tight. He finally got the negative tight after pounding on it. When I started the truck it idled a lot lower than it normally did, and almost stalled. I started it again and it seemed a little better. He told me there was a module that caused the low ideling and said it would get better. When I got home I noticed he had cracked the negative terminal. I finally got the right battery and returned the old one. I called the toyota dealer and was told I can not buy a replacement negative terminal, I had to buy the whole harness. Do I have to use a copper harness? Or can I buy a lead one from the parts store. I notice the truck seems to be idling at a lower RPM than before I changed the battery. Could a bad terminal cause this? What RPM should the truck be idling at? I have a v8. Thanks for you help. Happy Easter.
