Recently I had to replace the battery in my blazer so I bought a new one got it put on I am now nothing comes on at all! Everything I’ve read so far states that I need to reset it somehow I am a Widow my husband passed away two years ago and I am very unfamiliar with anything related to something like this my dad is stopped with all the new electrical things and if anyone could help me run through how to do a reset on this I would be grateful!!!!! If someone thinks that the problem could be something different I would be accepting of all suggestions at this point because if I spend thousands of dollars that I don’t have to get it looked at but it’s just a computer reset…
I might would be very upset

 

What do you mean nothing comes on? No dash lights, no electrical power of any sort? Who replaced the battery? Did it work at all after that? Is it possible the "new" battery is dead? Also, I know it sounds stupid, but sometimes new batteries come with a plastic cover on the terminals. I have seen somebody install the battery cable without removing the plastic thing first, and it obviously didn't work.

There may be a procedure it needs to go through (probably at a dealer) to "learn" the new battery for optimum charging, but that shouldn't keep it from working.
