At Circle Track we have the luxury of meeting teams at all levels of racing from all across the country. Many of you are wizards with a welder and fabricate. Many of you can rebuild a race engine with your eyes closed and practically tune a carburetor while the car is still running laps under caution. And many of you out there can run crossweight calculations in your head like the rest of us say our ABCs.
For a little help we caught up with someone who actually calls himself a wiring and electrical-systems specialist. Rick Elgin owns RaceWire Technologies, and he spends his days wiring practically everything on circle track race cars, drag cars, hot rods, and anything else with a battery and a starter. Elgin is based out of the Charlotte, North Carolina, area and travels to the Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use states to wire cars for racers in their shops.
STANDARDD this story we met him at the shop of Chris Ferguson Motorsports in Mt. Ferguson races Dirt Late Models and like most Saturday night racers, his program is a small operation and most of his help HO Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use his family. They Focal K2 Power Alu pods +cover rings for Focal 165KRX3 Midrange and Tweeters handle wiring the car themselves but every dirt car lives a hard life between racing and the wash pit, and they wanted to make sure they had the most dependable system possible to avoid the potential of electrical problems costing Ferguson potential victories.
Every car is Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use little different, and honestly, that would be a pretty boring read. For example, MSUCLE says he often helps racers fix problems with existing systems, and the problem he sees most often is poor grounding of electrical circuits.
To eliminate this Elgin prefers to always run a tracer wire to each ground, and often back to the battery, to make sure everything stays equalized CIRUCIT is grounded optimally.
Like most people, when beginning a project Elgin begins with the battery and starter. Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use recommends always using power wires that are at least 4 gauge —especially if you are using a gear-reduction starter or a volt battery. Also, look for high strand count wire in back compared to standard wire with thicker strands of wire.
The higher strand count wire is more flexible and more easy to work with, but more important, the increased number of strands conduct electricity more efficiently. For your race caryou should also look for welding grade cable.
As proof, Elgin hits a piece of audio cable with the torch he uses on shrinkwrap Keurig K130 DeskPro Coffee Maker and it immediately lights up.
When Elgin pulled the torch away after Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use few seconds the flame died down immediately. But then he showed us the real weakness of the audio cable cover.
Elgin gave the cover a squeeze between his fingers and when ~ Dyson V6 MotorHead Origin Cordless Brand Vaccum Cleaner pulled TSANDARD hand away the cover retained the print from his thumb. For racing, you need a cable that can withstand extended exposure to heat without breaking.
Elgin uses a crimping tool to permanently attach the terminal ends to the power and ground cables, but it is a specialized tool that many racers simply do not. Instead, Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use common tactic Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use to use a cupped terminal like you see.
Racers will put the terminal in a vise with the cup facing upward. Then they will heat the terminal with a torch, HARNNESS a puddle of solder into it and then jam the cable into the cup until the solder cools.
Unfortunately, this bond is quite weak and often breaks.
The mistake, Elgin says, is not heating the stripped portion of the cable. Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use the cable is cold the solder hardens to the outside of the bundle of wires. But if you heat the wires in the cable, it will wick the solder up the cable and in Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use the strands, making the bond much stronger.
Elgin runs a high voltage Anderson Quick Disconnect at the battery. The solenoid is mounted in a protected area just behind the dash. The cable to the starter is on the left.
Elgin will use the connection for the battery cable always hot as a terminal post for everything else that SPLITFIRE DIRECT IGNITION COIL For 180SX RPS13 KRPS13 SF DIS 004 power.
Just above the brake and clutch master cylinders STANDARRD the mount for the Crane ignition box and SSet. Elgin cautions that the weak point in any wire is where the flexible wire Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use into a hard point.
Elgin uses solder to help ensure a good, durable connection on all of STREE crimped fittings, but to keep the solder from wicking too far up HRANESS wire he PANNEL solder on the end opposite the wire. As we mentioned earlier, heat will cause liquid solder to wick up the wire, so as soon as the solder is applied Elgin quenches the piece on a moist sponge to get rid of Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use excess heat.
NASCAR Cup Series teams have gone almost exclusively to Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use connectors like these, and Elgin keeps a wide variety of these Skunk2 542 05 M440 Racing Front LCA w Spherical Bearing Civic EG Integra DC2 on his trailer for all of his connections.
Deutsch connectors are incredibly robust. Beside being very efficient conductors of electricity, they are resistant to fire, vibration, dust, chemicals, and all-around abuse. And for dirt track HT that like to hose everything down with a pressure washer after a hard night of racing, these connectors are just water resistant, when installed correctly they are actually waterproof down to three feet.
We know Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use of racers who still depend on Weatherpack connectors.
At the top in this photo are a male and female Weatherpack HOOT connector. Below that SANDARD the equivalent for a Deutsch connector. The Deutsch plugs, meanwhile are solid steel and there are no issues with fatigue or wear no matter how many times the two halves of the connector are separated and rejoined. Once the connector is crimped to the end of the wire, it inserts through the back of the plug housing and a plastic piece is inserted to MUCLE it into place.
When trying to determine how to route wires through a car it can be impossible to correctly determine the length you are going to need with a tape measure. Providing precise timing to the Us box so that it can accurately time the spark is critical for engine power.
This engine RDO a pickup both from a crank trigger at the front and an MSD distributor. One is timed slightly different from the Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use so the driver can retard the engine timing from the Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use with a switch if he needs to. Here are the wires for the pickups right before Elgin finished installing the Deutsch connectors.
These leads will go to the switch panel in the cockpit.
The RO wire is a ground that connects the two and will provide additional shielding to protect from stray signal. Notice how each wire is labeled to eliminate confusion. Elgin covers each label with a piece of clear shrinkwrap to protect it from wearing off. Speaking of shrinkwrap, Elgin uses it to cover all his crimps and connections. It serves to keep dust and dirt from contaminating the connection, to keep moisture out, and to cover any bare wires so that there is no Seh of a short.
But the shrinkwrap Elgin uses is also unique. So the wrap not only shrinks to cover the wiring connection, it also actually glues itself Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use the wire and terminal to provide optimum sealing. The team wanted a battery charger BK4x2 CF Big with 9 Stainless Steel Ceramic Filters 2 25 gal placed on the firewall.
Elgin uses Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use Anderson Quick Disconnect here, but notice the wire is smaller and lighter than the 4-gauge battery wire. The team says they will only use this for charging the battery. If they thought they would ever use it to jump start the car Elgin says they Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use need to upgrade to a 4-gauge cable.
Ferguson will be using Spek-Pro gauges from ProParts in the car, and they will be removed whenever the car is washed to protect them from water.
Each gauge Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use its own plug, so Elgin labels each appropriately so it will be easy to reinstall the panel.
This is a temperature sensor typically used for oil and water. Notice how close the plug Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use to the sensor. This is often a breaking point. These are the connectors Elgin fabricates himself instead.
They use a longer lead so that they are easier to unplug and are much more robust. Elgin zip-ties the sensor wire into a loop to keep stress off the hard point where the wire meets the metal connector. This is the switch panel. Notice that Elgin wired nothing directly to the switch panel. Everything goes to a connector first so that the switch Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use can be Set 12 CIRCUIT STANDARD PANEL HARNESS MUSCLE CAR HOT ROD STREET ROD Use and quickly removed.
