How to Install the Auto Volt Gauge Wire
A volt gauge for an automobile measures the voltage in your vehicless electrical system. It typically functions only while the ignition is on, and an auto volt gauge may include a warning light for when the voltage is outside the normal operating range. You must mount an auto volt gauge where you can see it while driving, usually under the dashboard. The kit for an auto volt gauge contains mounting hardware specific to that volt gauge.
Instructions
- 1
Find a fuse in your vehicles fuse box that does not receive any current unless your vehicles ignition is on. Common choices include the fuse for your stereo system or your power windows. Pull this fuse from its socket.
2Attach the mount for the volt gauge in a convenient location, according to the instructions. This will typically require you to drill holes in the dashboard with a drill, and fasten the volt gauge mount with screws.
3Cut two lengths of 14-gauge electrical wire that are several feet long. Strip inch of the insulation from one end of each wire. Connect the bare end of one of these wires to the positive terminal of the voltage gauge with electrical tape. Connect the bare end of the other wire to the negative terminal of the voltage gauge with electrical wire. Attach the volt gauge to its mount according to the instructions.
4Route the free end of the negative wire to a grounded screw on the dashboard. Cut off the excess wire and strip the insulation from the last half inch of the wire. Loosen the grounded screw, wrap the wire around it and tighten the screw.
5Route the free end of the positive wire to the fuse box. Cut off the excess wire and strip inch of the insulation from the end of the wire. Push the bare end of the positive wire into the empty fuse socket and replace the fuse. Secure the end of the positive wire with electrical tape.
