Performance and Features
Remote Starter Switch Operation
The core function of the remote starter switch is to allow a single person to crank an engine from outside the vehicle. This is particularly useful for diagnostics, compression testing, or when working under the hood. The switch is rated for 12-volt operation with a current rating specified at 29.99 amps. It features a normally open contact type and a one-way circuit. A notable safety and operational feature is the integrated red power indicator light, which illuminates when the switch is connected to a live circuit, providing a visual warning to the user.
Spark Plug Testing Capability
The two inline spark testers are designed for quick diagnosis of ignition system faults. According to the manufacturer, the inline connection design allows for diagnosis within 30 seconds by displaying a clear visual spark indicator. The tester’s light is intended to show the color and quality of the spark, helping to identify problems within the ignition system or potential fuel issues. This provides a straightforward method to check whether spark is reaching the plug without needing to remove the plug and ground it manually, a common basic test.
Versatility and Application
The kit is marketed as a universal fit for all 12V gasoline engines. This broad compatibility covers everyday vehicles like cars and trucks, as well as smaller engines found in motorcycles, lawn mowers, and other equipment. The combination of tools in one kit is intended to solve the “entire process from ignition testing to remote start testing,” as stated by the manufacturer. The promise is a more efficient maintenance process, as the remote start function eliminates the need to be in the driver’s seat while cranking, and the spark testers offer a rapid diagnostic check.
Setup, Support and Ownership
Setup for the VCC 2-in-1 kit involves straightforward connections. The remote starter switch uses alligator clips to connect between the battery’s positive terminal and the starter solenoid’s trigger terminal, a standard procedure for these tools. The spark testers simply connect in-line between the spark plug and its boot. No complex configuration or software is required, aligning with its purpose as a physical diagnostic tool.
