Switches don't need to be grounded
It can depend on the make of the vehicle. On a Chrysler product, the switch provides ground.
no lol
you make a stykz figure dissaper then make a red line on the ground
Switch grass makes a good ground cover. It is also very ornamental. Plus it can be used to make ethanol.
No, it makes no difference. The selection of red and black "hot" wires on your 220 line is arbitrary.
check the switch! then check the harness to the bulb/switch make sure you have a power and a ground
It can be done but it requires knowledge about how a 3way is wired to convert it to a regular switch. It would involve testing live wires to determine where power starts at. You can't just replace one switch.
If it works -- go for it
Use the symbols for a battery, switch and bell and connect them together with a line starting at one side of the battery. From the battery series connect the switch and bell and then a line back to the battery.
One can easily be installed. Locate the wire that runs to the water temp sensor. Splice this wire to a switch and then off to a ground. When you flip the switch it will ground the wire and make the fan come on. Do not get confused with the oil temp sensor. It controls the HOT oil light, not the fan.
It could be the ground wire, the brake light switch, a damaged wire or connector or the turn signal switch.
