1940 ammeter wiring question.

[FROG_PONDS]

I am restoring a 40 ford pickup that I got all apart. Let me start at the ''wiring'' beginning. Looking at the rear of the gauge cluster I see four gauges. The two on the left and the two gauges on the right have a brass bar between the two outside posts on both sets of gauges. I decided to install a''Rebel Wire''wiring harness with 8 circuits. The wiring diagram indicated a 10 gauge wire be run from the battery side of the solenoid thru a fuseable link to one post on the ammeter and from the other post on the ammeter to a junction box. Now it indicated to run a 10 gauge wire from the junction box over to the ''B'' post on the regulator. It also indicated to run a 10 gauge wire from the junction box to the fuse box. Before I ran the wires I removed the brass bar from the one post on the ammeter. Now my first startup I burnt up the fuseable link. After looking for a long time I found my dead short. I found out the ammeter was infact grounded at the post that had the brass bar. I then added a fiber washer to the post that was grounded, reconnected the wire and now I have no power to the fuse box. My questionis can I run both wires to one side of the ammeter and ground the other post? Rich
