Hands-on Electrical Basics For the
1955, 1956, 1957 Tri Five Classic Chevrolet
I have compiled some how-tos and wiring tips to help you along.
- Strip one inch of insulation off each the end of the wires to be spliced (connected).
- Twist the ends of the now exposed stranded wire to make it more manageable and solid.
- Add a length of heat shrink tubing over and past one of the stripped ends.
- Wrap the two wire ends together.
- Put cleaning rosin on the twisted connection, apply heat to melt the rosin for it to clean the wire for the best solder adhesion. Use rosin-core solder for electrical soldering
- Apply heat near the center of the splice.
- When the wire is hot enough to melt the solder introduce the solder to the heated wire and the solder will melt and fuse the wires together.
- Allow to cool. Insure that the wire is not overheated for it may become brittle and the insulation may melt.
- Slide the shrink tubing over the splice and apply heat. A cigarette lighter may be used, although care must be taken not to burn the shrink wrap tubing. A heat gun is the best tool to use to heat the shrink wrap into a tight coating of the splice and soldered wires. A hair dryer will not make enough heat to properly apply the shrink wrap.
- Strip the wire back just enough for the bare end to reach through the inner sleeve.
- Place the connector over the stripped end.
- Using the correct crimp size oval of a crimping pliers, crimp the connector.
- Tug on the connector to test to see if it will stay on.
Tri-Five Chevrolet and Vintage Automotive Electrical Circuits:
TRI5 wiring circuits use a negative ground. The best way in the simplest terms is to describe a complete electrical circuit is that power comes from the positive side of the battery down the wire to a light bulb. The electrical current illuminates the bulb. To light the bulb the current must be in
a loop from the battery to the bulb (load) and back to the battery. The AC wire used in your home has two wires for a circuit. The power flows to the bulb and returns to the power source by another wire. A car circuit has power to the bulb and to complete the loop the bulb’s socket is grounded to bare metal. That metal to metal connection mostly by the frame of the car returns the electrical flow to the battery. This explanation is not totally correct but gives the unknowing person a basic understanding of electricity.
