Yes, reversing the connections on a car battery can damage the battery. This is because when you reverse the connections, the + and – terminals are reversed, which causes a chemical reaction that can damage the battery. What are the Consequences of Reversing the Connections on a Car Battery?
If you reverse the connections on a car battery, it will not charge. This is because the polarity of the battery is reversed, and the charging system in the car is designed to work with the correct polarity. If you reverse the connections, the charging system will actually work against the battery, causing it to discharge instead of charge.
If you put a battery backward, the electrical current will flow from the negative terminal to the positive terminal, but it will not be able to power the device because it cannot flow through the circuit. What Happens If You Connect Positive to Negative on a Car Battery?
To reverse the action as prior, fully discharge the (reversed charged) battery and connect it to the right terminals (i.e. negative to the negative and positive to the positive terminals of charger and battery respectively). Again, wear the rubber gloves and glasses and other safety measures for proper protection while playing with batteries.
Battery reverse polarity is the case when the source (for charging) or load cables are connected incorrectly i.e. source or load Negative to the Positive of battery and source or load Positive to the Negative terminal of the battery.
If the battery polarity is reversed on a vehicle fitted with an alternator, the effect will be that the alternator will not charge the battery. This is because the alternator needs to have its positive terminal connected to the battery’s positive terminal in order for it to work.
electrical
Alternators are meant to maintain battery charge and not to charge a totally dead battery as it would draw a very high current that may damage the alternator and, yes, melt the fuse. I replaced the fuse box, sanded well all the contacts, …
reversed battery polarity | Boat Repair Forum
The motor doesn''t need a battery to run once the engine is started. It does need to charge the battery to keep from damaging the charging circuit/stator. The ignition system is on its own pretty much once the motor is running. I''m not sure the two are related. Maybe someone else will chip in here with other ideas.

Will a fan motor run in reverse if the receptacle''s polarity is ...
Just for amusement, I''ll mention that three-phase motors are a different deal. Three-phase power is sequenced, first phase 1 peaks, then phase 2, then phase 3, which defines motor rotation. They are reversed by switching any two wires (1-3-2). Also, many DC motors also don''t reverse if you reverse polarity.

Would a burnt out blower motor cause a battery draw?
I''d still check the motor by itself first. If you disconnect the motor and can access the terminals of the resistor, you should be able to check the resistor as well if you like.
