In this case, wire it between the Mastercell input and the connector on the switch, with the line on the diode towards the switch.

Since diodes are directional (they let voltage flow in only one direction), you have to install it in the right orientation. Installation is easy- just insert the diode in the circuit between the switch and the Mastercell.

The simple solution is to use a diode in series with the Mastercell wire for the start button/switch.Īlmost any diode will do, but a popular and cheap one is the 1N4001, available at Amazon , Digikey and everywhere else. Luckily, you don't have to give up your switch choice to use it safely with the Infinitybox system. Many others probably have the same problem. All have internal lighting circuits that have been known to, in some circumstances, leak voltage to the switched circuit. Some switches where this has been known to be a problem include the popular Honda S2000 switch, the Nissan GT-R-style switch, and the VW Touareg/Phaeton switch. Really, any switch with any kind of light (an LED surround, or lit-up status lights, etc) is a potential candidate for causing this problem. Even small transients can fool the Mastercell. So, for engine start situations, it's especially important not to allow any stray voltage to the Mastercell input. Like another car at a car show, which would make your new car a star on the Internet fail video circuit. If you left the car in gear, and didn't have a clutch safety switch installed, your car could start, and drive itself into the nearest solid object. The result? Your engine might start, even with no one in the car. Such leaks are bad, not only because there is the possibility of damage to the Mastercell, but more importantly, because they can confuse the Mastercell into thinking that the switch status has changed.
But some of the fancier switches from the OEMs have been known to leak voltage from the lighting circuit of the switch to the actual switching circuit. In the simple case of an unlit switch, this is pretty easy. It's vital that the switch you choose doesn't alow any stray voltage to the Mastercell. It's that erratic switch action that concerns us here. Any externall-sourced voltage on the circuit to the Mastercell can damage it, or more subtly, cause erratic action of the switch. In other words, the switch for all inputs must close the circuit, using the wire from the Mastercell, to ground.
First, a little background- as documented in the Infinitybox manual, all inputs to the Mastercell must be ground-switched. This is a great feature, but there is a potential problem. There are literally thousands of switches that could be used, allowing each builder to select one that meets the design aesthetic of their car. One of the advanced features of the Infinitybox system is the ability to have a simple connection to almost any switch that can be used to start the car.
