A couple of days ago I finally picked up my 1971 240z at the port. Upon arrival the battery was dead. This was no surprise to me, since I knew the battery wasn't too good.
The trouble started when I got the car home. When charging the batteries, I accidentally connected the battery charger wrong way around. Fore some reason the cables going from the negative side was red, and the positive cable was black. I therefor automatically hooked it up the wrong way around.
After a couple of minutes the battery chargers thermal fuse shut it off, and I came to realize my mistake. I connected it the right way and left it to charge. Trouble is when I now try turning the key, nothing happens. I have no electricity what so ever. No lights no nothing.
I bought a new battery, since the old one was bad, and to eliminate that as a problem.
And I have done some searching around. My first guess as a bad fusible link. I found it has been removed and a cable has been spliced in, hopefully a fusible one. My multimeter tells me there is continuity all the way from the cabel shoe to the fuse block. But as the rubber on the cable is melted, and since I am not sure it's even a fusible link, I will replace it with a new cable and a maxi fuse trouble is, I'm not sure this solves the problem.
My other guess is the amp gauge. (I read somewhere the amp gauge was not to fond of reversing the electrics)But I was wondering if any of you guys have any suggestions on what could be wrong.
