Topic: 41 Coupe amp gauge wiring


lowgear    -- 09-16-2017 @ 5:17 PM
  So I am wiring this car from scratch, keeping it original 6V.P.G. I bought new Stewart Warner Amp. gauge. I also got new 10 block mini fuse panel that is fed from solenoid. So is the proper way to wire ? ( Batt. wire from regulator to one side of gauge, the other side to new panel) ?? Thanks

  The wiring you suggest would measure the current from the generator. The factory approach is to measure the current to and from the battery since most of the interest is if the battery is draining or being charged. To measure the current to and from the battery (except that going to the starter), the amp gauge is connected in series from the (starter) solenoid and then to the other circuits which could include your fuse panel (if you want all your circuits protected by the fuse panel). Note that in this case, the current to/from the battery could be zero as the generator is supplying all the current needed. Your approach would only show generator output. Of course if you use the Ford amp gauge as the factory wired it and your gauge, you could see both generator and battery currents.

  I would investigate buying a wiring harness for your car. Building your own is difficult and more costly because you have to buy all of the different gauge wire used in the car and the special connectors and then organize the harness so it doesn't look like a rats nest. A good wiring harness has all of the terminals soldered to the wire. A crimped connection can corrode and create resistance after a few years.
