"Bubba" has been an A/Q customer for years, in circle-track race cars for both asphalt and dirt tracks. I began working on his cars when he would race the dirt track at Lakeside Speedway on Friday nights and then take the long drive out to Dodge City, Kansas for the asphalt track at Dodge City Raceway Park on Saturday nights.
These Modified class cars are the feature class at Lakeside -- methanol-burning monsters that thrill the crowds with their sideways-through-the-corner, wheel-to-wheel action. With stiff competition only inches away, this is no place for your electrical system to give you trouble. With two dirt-track modifieds, he keeps us busy. Here's the typical equipment on one of his cars:
- MSD Ignition system
- Independent ignition power and starter operation switches
- Remote-mounted starter solenoid
- Single-wire alternator
- Electronic memory tachometer
- Warning lights for low oil pressure, high water temperature and low fuel pressure
- Gauge illumination (with the operation of ignition power switch)
- Remote starter "bump" switch, mounted on the engine-side of the firewall (allows the engine to be cranked without reaching into the driver's compartment)
- Track-required master power disconnect
The work was accomplished at Bubba's shop, using a pre-built instrument panel and harness constructed on-site. The system design is typical of the A/Q-equipped circle-track cars over the years, the most important feature is routing the wires to insure they are away from any heat sources and also placed to provide maximum protection from track debris.
Here are some pictures of the car and the wiring installation:

We are proud to have wired Bubba's cars for several years now, and look forward to working for him in the future.
