User questions & answers

Question:	What is the fitting size on the back of the oil pressure gauge? compression fitting? 1/8" npt? I want to use a braided line rather than nylon
Answer:	From the Autometer site: https://www.autometer.com/2-3-gauge-console-oil-water-volt-mech-black-2293.html SHIPPED WITH Adapter/Fitting - 1/8" NPT Male to 1/8" compression fitting, 1/8" NPT Female to 1/8" compression fitting, 1/8" NPT to 1/4" NPT bushing, 3/8" NPT and 1/2" NPT adapter fittings. Tubing - 10 ft. nylon tubing - 6 ft. Capillary Tube Bulb & Socket - 2357 Mounting Hardware - Bracket Included
Question:	Are all of the things i need to install this kit included already
Answer:	I installed the gauge set on a 1957 Case tractor. Everything was included to connect the temperature and oil pressure gauges to the engine. I had to fabricate a small metal bracket to mount the gauge cluster and add a couple pieces of wire to connect the volt meter and gauge lights into the appropriate circuits. Everything is working great. Hope this helps, good luck!
Question:	What size steel braided hose could I use instead of the crappy nylon tube for the oil pressure
Answer:	The size of the line is 1/8TH. I have used the plastic line for 30 years without failure. Put some loom over it for protection.
Question:	are they electric or mechanical
Answer:	Mechanical water and oil, electric volt.

User questions & answers

Question:	Would you choose this model or another for automotive diagnosing
Answer:	To answer your question I'm a master Automotive technician most of the people in the business use flukes but our use these ones because they are accurate and work just as good as the fluke when it comes to Automotive Diagnostics. There is nothing you can't do with this digital multimeter that you can do with a fluke
Question:	I have been trying to measure the ac/dc amps with this but doesn't work. i wanted to know if i am missing something or its actually faulty
Answer:	Make sure you have the leads in the proper slots or ports for the amperage reading.
Question:	What does "4000 counts" mean
Answer:	Counts and digits are terms used to describe a digital multimeter's resolution. Today it is more common to classify digital multimeters by the total counts than by digits. Counts: A digital multimeter resolution is also specified in counts. Higher counts provide better resolution for certain measurements.
Question:	Do the Battery Test selections test under load
Answer:	battery test 1.5v 30 ohm load 9v-12v 300 ohms load

User questions & answers

Question:	Can you use this for car audio for an amplifier ro see the volts
Answer:	I am afraid that any decent car audio amplifier would require much Much more power than what this little car charger can supply. Based on what my son used to ask for when he was a teenager, a decent car audio will require 50W per channel. Note that this is per channel. He may want to have another 200W to 500W for bass. My son is all grown up now. I use this charger for my GPS and cell phone when driving. For this purpose, no problem at all. I love it.
Question:	why does this not charge my phone over 1 amp
Answer:	Current rating is the amount of current draw available. A device may only require 1 amp to charge and that is all the charger will deliver.
Question:	Is there anything like this that will quick charge a phone here at Amazon
Answer:	Tons of items. External batteries, devices to plug in receptacles.
Question:	will this accept a 5s smart phone
Answer:	Dear Anthony,We believe this charger can work well with your 5S.

Question:	Is this 2 5/8 or
Answer:	2 1/16"

Product description

The voltmeter gauge indicates electical pressure or voltage, It provides easy to understand information on the condition and operation of your vehicle's electrical system.

Under normal conditions the volmeter will indicate between 13 to 15 bolts while the car is being operated at usual road speeds. If the gauge reads higher than 15 volts, it indicates that the charging system's voltage regulator is not operating properly and it can result in damage to the battery and accessories. A continuous reading of less than 13 volts indicates that the charging system is not operating properly and will eventually result in a discharging battery.

If the voltmeter reads too high or too low at normal operating conditions, the battery, the starting system,and the charging system should be throughly tested and serviced as necessary.
