Will a short to ground drain a battery?
A bad ground would not cause this. This is called a parastic loss. That is when there is too much current being drained from the battery with the key in the off position. When this happens, it may keep the charging circuit on after the vehicle engine is shut off, which will cause the battery to drain.
What is short to battery and short to ground?
Short to ground – A short to ground refers to a current flowing from the circuit to the car body. Short to power – In the wire harness, with many circuits in close proximity, there is the possibility of a short to power fault.
Can a short to ground cause a parasitic draw?
A bad ground would not cause this. This is called a parastic loss. That is when there is too much current being drained from the battery with the key in the off position.
What happens when you short the positive terminal?
Subsequent shorting of the positive terminal to ground will then produce no current flow because the current has no return path to the negative post. And, of course, always reconnect the ground last.
Why is there no current on the negative terminal?
If you remove the negative clamp and inadvertently complete a circuit to ground, there will be no current flow because the ground clamp is already grounded. Subsequent shorting of the positive terminal to ground will then produce no current flow because the current has no return path to the negative post.
What are the terminals on a flasher relay?
Flasher relays have a power source terminal, sometimes labeled “B” for battery, a load terminal labeled “L” and a panel, or dash-indicator terminal, labeled “P.”.
Is it bad to connect a battery to a negative post?
(Connecting electrical devices or hardware directly to a battery negative post is a bad idea (no matter who tells you to do it) unless the negative connection is 100% ground isolated at the electrical device.)
Why do flashers need to be connected to ground?
This wire needs to be connected directly to ground. In the simplest case, that would be a piece of sheet-metal of the vehicle. The reason your flasher may have this is because none of the terminals of the flasher socket in the original vehicle design was grounded.
What do you need to know about LED flashers?
What is an LED Flasher? An LED (-compatible) Flasher is a turn-signal or hazard flasher relay that works properly with LED turn-signal bulbs. Generally, a stock automotive Turn Signal (or Hazard) Flasher Relay does not work with LED Bulbs unless it was designed for that.
What should I do if my Flasher is not wired?
Your electronic flasher, however, requires that the socket is wired correctly. If it’s not, you have two options to fix this: #1 is to try and rewire the socket. That’s easy if the socket is “stand-alone” and you can get to the back of it. Just swap the X and L terminals in the socket.
Why is my car Flasher not working properly?
Because you’re noticing that the turn-signal or hazard lights aren’t flashing properly. Stock flashers (i.e. the one that came with the car) may be of the thermal or electronic-with-lamp-out type. Thermal flashers require that your bulbs consume a minimum amount of load, usually 15 Watts or more, to function properly.
