Mostly positive side switched but it has a couple ground side switches also such as the courtesy lights.
Headlights in the US are generally positive switched, because the best source of return current is vehicle ground, and US cars are generally a positive voltage system. However, if Daytime Running Lights (DRL) are employed, often the high beams are wired in series, so as to illuminate at about one quarter power, so the concept of which end is switched becomes vague. Usually, one is positive switched, and the other is positive switched between switched positive and the negative side of the first.
it keeps it balanced
no matter what vehical it is, the proper way to disconnect a battery is to disconnect the ground side first ,then the positive side to reconnect it is exactly opposite you connect positive side irst then connect ground side ground side in case your not sure is the negative side of battery
The side of the plug with the ground wire is or should be the negative and the side with just the center screws is the positive.
the positive side, the negative side is usually just a ground
Yes. It's on the positive side of the coil.
Yes, they can be switched to whichever way is most convenient. The goal is to maintain positive pressure through the crankcase.
Check switch iin glove compartment left side facing. you may have inadvertaly switched it off.
Dim lights are almost always a bad ground connection on the dim light, just loosen and retighten the ground wire to restore the connection.
Your coil has a positive and negative side and if there is no power to the positive side you will not have any spark: However, if you have no ground to the negative side you will have the same problem. Check for power and ground with a volt meter.To check for power, connect red lead from volt meter to positive side of coil and black lead to negative side of battery, you should read 12 volts with key on. To check ground, connect black lead from volt meter to negative side of coil and red lead to positive side of battery, you should read 12 volts with key on.
Its passenger side under the lights looking up from the ground
2001 s500 battery is located in the trunk, under the trunk floor mate on the right side. It should have a black cover over the battery. just remove the cover and discount positive and ground wire.
