Can someone please post a few pics of all the ground locations in the engine bay...I think I'm missing my firewall ground but have no idea where it needs to be...thanks in advance..
Yeah I've looked everywhere, which is why I posted here...im tempted to just randomly stop someone who has a mustang and ask to look under their hood...
No firewall ground, just the ones by the radiator/left headlight, and the main ground from the left motor mount to block.
There is a fuel rail ground that is by the firewall. That just gets capped onto a valve cover stud.
Let me know if you still need pics.
Thanks, I have all those, just figured I was missing the firewall ground because any time I turn on any accessories like the defroster, my battery gauge takes a nice hit to it....I've got a brand new battery and alternator...maybe I need to upgrade to a high output alternator...
defrost does the same to mine.(when it used to work)
grab a volt meter and check what the voltage is at the alt and the battery.
make sure the connections at the posts are tight and clean.
