In the case of broken wires, electrical current from your battery will not reach the starter. If so, it carries a chassis ground from the body through the starter to the solenoid. The total effect of all this unwanted resistance is a dramatically reduced current flow, which in turn means the starter is limited in current, and therefore either turns very slowly or not at all.
The battery posts get very hot along with the cables and the starter itself. Voltmeter (+) test lead to battery (+) post. That along with the high amount of power it is using to try and start will make it get very hot.

The starter system is not designed to crank for long periods of time, a few seconds is normally what is required and we tend to activate the starter too. Do not allow the cables to touch on the free end not yet hooked into another battery while the cables are connected to the first battery.
Battery terminals and cables will only get hot if there is increased resistance in the cable causing the cable to heat up. The terminals on a lead acid battery can even melt from the heat. Determine the root cause that it won't start and then try again after it cools off.
Keep in mind the vehicles positive battery cable will be hot even after the vehicles battery is removed. Test the positive battery cable by connecting the red lead from the multimeter to the positive battery terminal. When attaching the battery cables, place the positive cable on first and then the ground cable.
Disconnect the red wire from the starter solinoid to the starter and crank key like you are going to start it. Often, a poor connection at one of the battery cables can cause the starter motor not to work. 5 / 5 when selecting the correct size of a battery cable to power your electrical system or project, a few factors need to be considered.you should know what is the maximum amount of current your system will need, how long the cables need to be, and the cost of larger cables versus smaller cables.
