To measure battery load, conduct three voltage tests with the multimeter. Start the first test by making sure the vehicle is turned off. Multimeters have two probes: red and black. The red probe is for contact with the positive terminal and the black probe is for contact with the negative ...
Just like you would test power and ground, you can test your remote turn on wire. With the ignition in the OFF position, place the positive lead of the multimeter on the end of the remote turn on wire and place the negative lead of the multimeter to a grounding point. Be sure the po...
The transistor-controlled relay mentioned above enables you to switch very large amounts of current on or off. This enables you to switch large devices such as your washer/dryer, heater, air conditioner, car starter, among other things on or off with your Arduino. ...
For idling voltage, the battery should maintain a steady draw at 14-14.5 volts (under 14 volts implies a weak battery or a failing alternator). You can also use a multimeter to test thealternator. In addition to acquiring a multimeter, a mobile charger, jumper cables, and cleaning gear for...

My multimeter says I had perfect conductivity...without the extra expense. Really, though, If I were making many such connections, through the years, I would certainly invest in the tools to do so. But, I am not. I mean, why buy (or rent) a car for my one day visit to a faraway...
This procedure requires common tools that I'm not going to try to list. Some necessary less-common tools: Plastic pry tool/trim removal tool Multimeter (preferred) or test light Crimping and wire stripping tool Candle lighter or cigarette lighter for shrinking heat shrink t...
Now you will need to connect your multimeter to show you how much battery is drawing Set your multimeter to 10A and connect it in series with charger and battery When you connect it to the battery an it should draw 100-200mA Thats sign of dead battery ...
With the lights up, the total draw on the battery is 15 amps or more. Any resistance between the clamp and the post will cause a measurable voltage drop. It shouldn't be more than a few millivolts. Chase the circuit toward the lamp, one metal-to-metal junction at a time. Probing ...
