wiring help

[elwood]

hey guys, im installing this harness in a 34 roadster, problem is the amp gauge is the pass through type, so i plan on cold crimping the ends together, but not sure which way to pass the wires through.
on my 50 f1 it has a pass through type, and when i ran the wire the wrong way, the amp gauge worked backwards..
any advice appreciated ...

Take any substantial load, like a headlight bulb or heater motor, or an ignition coil. Put a lead to ground on ground side of the load (actually, either side will work). Fasten another long lead to the non-ground side of the car battery (the negative side if you are staying with the 6v positive ground of the original '34, or the positive side if you have converted to 12v negative ground). Run that lead through the ammeter loop.

Touch that lead to the other side of the load. If the ammeter needle jumps negative, you have identified the load side and battery side of the loop on the ammeter. If the ammeter jumps positive, the correct load and battery side of the loop are opposite of the test rig. Mark the back of the gauge to indicate load and battery side of the loop.

The wire from the harness will pass through the bottom of the gauge and out the top and then to the fuse block. Cut the eyelet end off the wire and remove the rubber sleeve insulator to pass it through the gauge and just crimp one new end back in place. Easy to solder after crimping. Don't forget to reinstall the rubber insulator before crimping the new eyelet in place. The wire should be yellow in color and very long, I do not see it in the harness you picture. The 33 ammeter has terminals and not the loop and the wiring is different. Not the same as your instruction imply.
