im trying to use this multimeter to find out if the sensor or wires are bad on my coolant temp gauge. what do i set it to, what is a good reading, and where should i place the test leads. thanks
Just set it to auto and put the leads before and after where u want to measure Sent from my iPhone using Grasscity Forum mobile app while high as fuck
Send me a pic of your multimeter bro! Sent from my iPhone using Grasscity Forum mobile app while high as fuck
You want ACV, cars barely use DC. And put the red lead on the power side of the gauge and the black on the ground side, and read the volts, as for whats a god reading, you would have to look your specific car up.
direct current is only in the alternator if I'm not mistaken? Then it is converted to Ac throughout the rest of the car, what else is DC? Sent from my SGH-T999 using Grasscity Forum mobile app
Lots and lots. Stereos, power antennas, amplifiers (which convert dc to ac for speakers), alarms, remote starts, cig lighters, etc... Srry i'm soooooooooo high fresh off some beautiful blueberry nug testers and I'm just listing things I work with. For instance, you'd need a AC/DC converter to run a car radio off of house power (AC).
Alternators charge the batt in your car. They use diodes to convert to DC which the batt needs. Diodes basically only let electricity go one way (DC). With a solid 12v charge the battery runs everything else pretty much on direct current. Hope that helps
OK You are using an Innova? What kind of sensor? Is it an O2 sensor, whiich is a powered active sensor, or a 2-or 3- wire sensor? What kind of car? If you want specific help, be more specific. Cars have voltage, amperage and resistive based sensors. If you had a Fluke MM like mentioned before they have an auto setting.
