If an engine starter is wired incorrectly, it can cause a number of problems in the starter circuit. The most common problem is that the engine will not start. The current will not flow through the starter correctly and the engine will not start. This is because the starter needs a certain amount of current to flow through it in order to work properly. If the current is not flowing through the starter correctly, then the engine will not start. In some cases, a short circuit can occur and the starter can overheat and gets damaged.
