ARTILAURA Triple Gauge Set 3in1 (Oil Pressure+ Watertemp + Voltmeter) 2" 52mm AUTO Boat Gauge Kit with Sensor for Marine Black

Easy hook up bright leds good so far!!!!

I cannot beleive Amazon still sells this after reading the reviews, which I did not prior to purchasing. I purchased 2 of these because of the issues I found with the first one. I had to be sure it was not just a defective sensor and it was not.I like the volt meter function since my Polaris 700 has a winch. It works correctly. The water temperature sensor has not been inserted but is connected and seems to work at 80F ambient. The Oil Pressure Sensor is the HUGE issue. It reads 10 - 20 psig HIGH as verified by an pressure gauge. I discovered this when my Cold/Idle OP was >100 psig. I can deal with that because I am good with Math. The issues is when my indicated OP goes to ZERO. I have a chart for this but let me summarize. My standby Battery voltage 12.2 VDC and when running is 14.2 the indicated OP is +10 - 20 psig high. When the Radatior fan comes on the indicated battery voltage drops to 13.7 and when it does the indicated OP drops to ZERO psig. this is what scared me in the fist place. When the fan shuts off the voltage returns to 14.2 and the OP returns to the 'normal' 10 -20 psig high. The problem is I cut my dash to fit this gauge and there is not another product to match it one with 3 functions. My WoO (Window of Opportunity) to return the first one is gone so I am stuck with the POS. The Chinese cannot design this to prevent this from occurring and continue to sell this POS???

Temperature works correctly. Oil pressure goes up or down as much as 10 psi depending on battery voltage. Should have a voltage regulator internally but it does not. Voltage works correctly. Temperature uses thermistor so it is not affected by voltage. Still usable if you are aware of problem.

This is absolute junk! It looks awesome when installed but I quickly figured out how inaccurate it is. I read the reviews before buying and decided that maybe, just maybe, I would have better luck with it than everyone else and upon initial install I thought this was the case. Unfortunately it quickly proved me wrong. The oil pressure was initially looking accurate, running at 62 psi, unfortunately as I was driving it would jump to 80 psi then down to 0 psi. My original mechanical gauge varied but only by 20 PSI at the max. The temperature looked good after I installed the gauge too but this morning, with an overnight temperature of 32 degrees, I started the engine with it reading 62 degrees. I though that maybe that was the lowest it could read but within a couple of minutes the temperature started to climb. The volt meter is about the only thing that works and its kind of flaky too. This gauge goes up and down nearly 1 volt while my other gauge only varies by .3 volts.The instructions are not good, thankfully another reviewer helped with getting the oil pressure gauge working correctly. The "G" goes to the gauge and the "W" goes to ground. None of that is mentioned in the sheet that comes with it.While it looks good, the lack of accuracy makes this gauge worthless.

Install and everything worked great for a few minutes than the temperature sending unit quit

This amends my earlier comments. I installed in my boat on a small diesel engine. It was carefully wired with a solid ground at the engine. Oil pressure did not read correctly and after a lot of work I found the most simple explanation. "G" on the sending unit is NOT to be the Ground, rather it is the signal terminal. The "manual" - only a wiring diagram - shows two terminals and a chassis ground. There is no identification of which terminal to use. (G or W). I assumed G to be ground. Had it made this clear I would never of had any problem. With a better detailed instruction to eliminate possible hookup error I would have given it 5 stars.

There are no instructions for the oil pressure sending units. There are 2 posts, one labeled G and the other labeled WR. Usually G means Ground, but not on this, it goes to the gauge, and Wr goes to ground. Otherwise the reading is way off and it goes into protection mode

Installed it pretty quick, and the gauge itself seems well made. But after comparing to a mechanical -oil pressure and coolant temperature gauge, they are both off . After bringing the truck up to operating temperature The coolant temp on this gauge read a max of 140*f . when the mechanical gauge read 191-195*f . Which I confirmed with an infrared thermometer. And the oil pressure gauge at cold start read a very high 87-91psi (actual psi 60-66)and at operating temperature idle read 36-43psi. (Actual psi 21-24). Voltage was spot on though….
