I'm a novice, for sure, but I've just finished replacing the passenger side head gasket because I broke the glow plug nearest the firewall. Everything was going relatively smoothly until I tried to hook the batteries back up. I took pictures of the bus bar before I disassembled it, and everything is back where it came from (on the bus bar). One question is: on the intake manifold stud near the rear of the rocker arm cover (passenger side) should there be 2 wires and the ground strap? Anyway, When I try to hook the rear battery up (front battery is not hooked up), the cable, bus bar, and gp relay all star smoking and there are sparks from the battery terminals. I must admit that I have tried to hook the batteries up incorrectly before, and what is happening now is similar to that experience. Any suggestions? for what it's worth, I haven't installed all the intake manifold bots and studs, but it's in place with a few bolts in, and the stud that holds the three wires mentioned earlier. Help appreciated.
