Swordlordboy1234 Posted January 13, 2014 Report Share Posted January 13, 2014 I would take that ground out and do a single proper ground to said strut tower. Requires removing one of the outside bolts and boring out the terminal... Sanding and retightening. Good luck sir.

SnowDrifter Posted January 13, 2014 Report Share Posted January 13, 2014 Here's the issue with self tapping screws on thin sheet metal It pulls up the metal it's attached to, lifting up the terminal so you only get contact around the inner ring of your terminal. See below Black = sheet metal Gray = self tapping screw Red = ring terminal See what happens? Poor contact area, source of resistance and voltage drop. Ideally, you want to ground to something fairly thick, such as a strut tower or frame. But if you need to ground to sheet metal, you should put washers on top of the ring terminal, and on the opposide side of the sheet metal, that way the terminal and metal are sandwitched between the washers, ensuring(insuring? don't kill me grammar Nazis ) that there is no metal deformation and as much contact area as possible Quote ~~~~~~~~SAY NO TO PHOTOBUCKET~~~~~~~~ Snow's DD-1 tracks here: https://www.stevemeadedesigns.com/board/topic/167433-snows-dd-1-tracks/ My take on OFC vs CCA: https://www.stevemeadedesigns.com/board/topic/110381-things-that-piss-you-off-in-the-car-audio-world/?do=findComment&comment=2461444 Link to comment Share on other sites More sharing options...

Well now i got a good game plan for tomorrow. Before i pull out my meter and start shooting im gonna start off my changing my ground. If its still inop then i'll take the readings and see if i notice anything out of the ordinary. Quote Link to comment Share on other sites More sharing options...
Swordlordboy1234 Posted January 13, 2014 Report Share Posted January 13, 2014 OP... Do you see why I said what I said about snow in my earlier post.

trevarislong Posted January 13, 2014 Author Report Share Posted January 13, 2014 So I haven't touched my car yet but I've been thinking.since my batteries are wired in series that would make my system a 24 volt system. My alt would see the front battery fully charged what if I added a voltage regulator so when either battery loses voltage it'll direct the charge to the respective battery. What do you guys think?

SnowDrifter Posted January 13, 2014 Report Share Posted January 13, 2014 Woahwoahwoahwoahwoah Unhook your back battery NOW. Do it IMMEDIATELY Wire in parallel, not series.
