The Hot wire of an automobile starter gets hot only after a prolonged attempt to start the engine, this is because the wire gauge or thickness is kept to the minimum acceptable size for normal use, starters are high amperage motors and when ran excessively and when the hot wire is sized to barely make, it it will get hot. There is also the case of a started drawing more amperage then it should because it is leaning and it is time to change it. The other sign is the engine will crank slower then usual and it sounds like you have a weak battery. Wires are gauged to carry a certain amount of amperage at a given voltage. It is my opinion that to keep the price competitive on most automobiles, manufacturers will skimp on materials when parts are made even expensive cars. Fortunately this wire getting hot is not such a big issue for most cars.

What else can I help you with?
When cranking the motor why does the hot wire on the coil go out?
When cranking, the ballast resistor is bypassed to give a hotter spark. If during cranking you do not have power at the coil, but when the key is turned to run you do; there is a problem with the bypass circuit (sometimes it comes from the starter motor solenoid wire)
What wire is the hot wire and ground wire in a 1990 cutlass supreme?
the hot wire goes to the starter and the ground wire bolts to the engine block.
Why does F150 starter burn out?
biggest problem with ford starters burning out is caused by a bad battery and prolonged engine turning over if hard to start. if starter has been replaced, your battery may not have correct cranking amps. bare in mind that a hot engine actually takes more cranking amps than a cold engine to start.
Why is wire from starter to firewall is getting hot and engine wont turn and the neutral safety switch is new starter is newand battery is new its on a 79 Chevy truck with 350 5.7?
A wire that is getting hot could be shorted to ground.
Car starter does not work when engine is warm?
Solenoid is getting hot from heat transfer. Wire in a remote solenoid.
Where is the starter motor located?
it depends on the car ..it either on the right or the left side of your engine trace your hot wire from the battery
How can you find out if your engine is ruined from your car overheating Why is it not cranking since your engine ran hot?
If it won't turn at all you may have caused a problem. Check to see if you can turn the engine by hand. Does the starter click and the engine start to move? I guess I don't understand what you mean when you say it is not cranking. If you want to pursue this problem any further, contact me at: a_d_kirkwood@excite.com
How do you hot wire a 1989 Ford F-150?
Why would you hotwire. Why not fix the problem?AnswerRun a wire from the negative battery terminal to the negative on the coil.Use a screwdriver on the starter selonoid to turn over the starter and start the engine.
Your daughters 1992 Geo Prizm will not crank sometimes when it is hot what could this be?
Could be a weak starter - requires more cranking power when hot
How can you tell if a starter is bad on a motorcycle?
Testing a StarterStarters, like all electrical devices need two conductors, a Positive/hot wire from the starter switch, and a ground wire to the chassis or back to the battery. Sometimes, the ground may be internal to the starter and thus there is only a single terminal or wire connector for a Positive wire from the starter switch.NOTE: The first step is to make sure that the transmission is in NEUTRAL!!!!! Also, leave the ignition switch off.On most motorcycles there is usually a wiring harness connector at the starter. I disconnect that harness [or if there is only a single wire to a terminal on the starter then disconnect it], and test the starter by connecting a wire from the ground wire [usually black] in the starter connector to the frame of the cycle, or to the battery negative terminal. This step is not necessary IF the starter is grounded internally.I then connect another wire to the hot wire [or terminal] on the starter or connector [Or the terminal on the starter if it is internally grounded.I then just very monetarily touch the other end of that wire to the Positive terminal of the battery.IF the starter cranks the engine, it is probably good. Sometimes, IF the brushes in the starter are worn out [or "glommed-up" with Carbon dust or other debris] the starter may try to crank the engine, but unsuccessfully.If the starter does not do anything, or tries but can't crank the engine, then it may be worn out and needs an overhaul or replacement.

Why does starter wire get hot when not cranking?
The starter probably has a short in one of the windings. So the power from the battery is flowing through the cable, through the starter and straight to ground. This is overloading the starter cable as it is not designed for that sort of load and is cooking itself. I suggest pulling the starter off and bringing it to an auto parts store to have it tested, or having the car towed to a repair garage for them to inspect and likely replace the starter.
