Battery issues...
maybe a 8g and I got the error of service battery, probably due to a lose negative wire.
Anyway I'm going to go back and reinstall stuff but has anyone
1- upgraded the wire from the fuse box to the positive battery wire? Looks a bit small
2- upgraded the battery ground wire cause it looks tiny compared to the others.
3- used a fuse between the negative or positive wire connections between the battery? Such as making the negative wire a bit longer using the fuse box cause it's such a pita to connect to the battery
4- remounted the ground wire to the chassis anywhere else?
This is for a 2007 Monte Carlo ss. Opinions please?
