Darn - didn't see the fourth battery get removed or re-installed. That's the tricky one. Also - at the end of the video - you say you put it into TOW then turn it on and test the brakes and then the video abruptly ends when you shift it into gear or something. But - I think I can hang with this and go get me some new batteries. Thanks!
At the beginning of the video, you state that the negative connection gets removed first, and it is the last to be connected. However, at the end of the video, you show the negative connected and the positive connection and then you add back the series cables. Please clarify the sequence.
I'm going to be honest with you cuz batteries are junk I've had my batteries for two years and they cannot handle a load they instantly drain and nothing I do will keep them up or they'll show their that their 13.5 until you put a load on them and it's going down tonight
