Hello all, this is my first post so sorry if its formatted I correctly. Long time lurker, I've been browsing forums, etc. To figure out this constant drain on my batteries voltage while the car is running. But to no avail. I'm mechanically inclined so I've replaced alternator etc. And done some voltage and load tests I've seen on forums but I'm requesting someone to come and assist me in troubleshooting this problem. Any help is much appreciated.
