Hey guys...
This may sound like a VERY silly question... But, when it comes to our era amp gauges, this case a 67 Plymouth, is there a proper "left" and "right" post when attaching the red and black wires? I would think the gauge just senses the current regardless of the way it is traveling through it... I could be wrong...
I went to hook up the battery after reinstalling the instrument cluster and dang, the fusible link went up and smoke. Smoke even came out of the ground point on the radiator core support where the negative battery cable body ground attaches... Never saw that one before... I quickly removed the positive cable from the battery and checked the wiring under the dash at the bulkhead connector and outside on the firewall. The only wire that seems to have been affected is the fusible link... Whew....
Sounds like you screwed the pooch, while the gauge is designed to work in series, there is correct manner in which the current flows thru the gauge, should be marked with "red", or "S" on the primary terminal of the gauge to receive the red wire, black/dark blue on the other terminal
FYI, replace those "paper" mounting insulators on the posts with some nylon washers...make sure your isolating the studs properly in the dash cluster
