Terminals Needed: This D-series battery does not come with battery terminals, so you will need to purchase the proper terminal adapters for your application before installation can take place: Car Stereo Installation: You will need terminal adapters that fit the inner diameter of your power ring terminals. Recommended terminal adapters include: Two 5/16" brass …
Abstract. Many self-contained critical electronic systems and subsystems, especially in automotive applications, use a 12 V or 48 V storage battery for the primary power source. To prevent extensive damage during operational life, these systems require the design-in of systems that—at a certain voltage level—provide protection from voltage polarity reversal.
Reverse polarity happens when the installer connects the hot wire on the neutral side and the neutral wire on the hot side. In other words, reverse polarity occurs when a receptacle''s wiring is backward. …
You can do this using a digital multimeter, which can measure the voltage of the car battery. To check for reverse polarity, set the multimeter to read DC volts and place the probes on the positive and negative terminals of the battery. If the reading is negative, the battery has reverse polarity. Diagnosing Reverse Polarity on a Car Battery
Reverse polarity happens when the installer connects the hot wire on the neutral side and the neutral wire on the hot side. In other words, reverse polarity occurs when a receptacle''s wiring is backward. This article will explain the hazards of reversed polarity and provide information on testing and fixing the problem.

I completely discharged the battery and tried a charger on it but it still sparks hard when I try to put the leads on correctly. ... Using a 24 volt charger is a good idea, but put a light bulb in series to act as a crude constant current source. Charge at less ...
After a bit of poking with my voltmeter and a shower of sparks when my ground terminal turned out to be hot, I realized that the polarity on my battery terminals was reversed. After a bit of reading, it seems like that since the battery was fully discharged it is susceptible being charged into a state of reversed polarity if the charger leads ...
After reading up on an article on this matter, it seems that the only way to fix this issue is to completely discharge the battery. Now since lead-acids do not want to discharge completely (80% is the rated limit before damage is done to the battery), there is no "safe" way to get rid of the reverse polarity effect on the batteryOne thing you could …
Specifically, when cells are in series, the one(s) with the least current capacity (due to imbalances during manufacture, or uneven deterioration) will be reverse …
It will tell you the battery voltage with the bike switched on. It will tell you the battery voltage when cranking. Also, are you certain the battery (+) and (-) terminals are in the same location on both the old and new batteries? I doubt the polarity has reversed, my bet is the new battery is just flat out dead. But a meter will tell you what ...

From what I read, the fuse is supposed to blow if the polarity is reversed, and Spektrum does not put a diode in series to protect for reverse polarity. I am somewhat apprehensive that the fuse didn''t blow. The fuse is the proper amperage and voltage, so I didn''t have too big of a fuse.
If there is a reversed biasing then-current reduces to zero. Here in this case if the polarity is reversed then the p-n junction becomes reversed biased, so there is zero current in the circuit. Hence option 4 is correct. Current through the intrinsic semiconductor and extrinsic semiconductor is independent of polarity. So options 1, 2 and 3 ...
