This is a very bright light, even in the sun. We wish there had been a fuse link included, as only two wires were needed. Honestly, I'm not sure if this unit can be left on all the time without being shut A never-ending cycle This is a In the absence of the key, I plan to install them on the key switch so those units do not turn on or Rather than using the ignition, I'll turn the switch to the on position and check the battery level. You should be able to do the installation yourself if you are handy with computers. As with my case, you will need to drill a hole in metal, which in my case is thin metal, and then secure it using a nut. The wiring- There is nothing under the wire that will not be cover by a few tie wraps or loom. My Volt/Ohm meter measured the unit within one tenth of a volt. The positive terminal of the battery to this unit should be handled with caution since if grounded, it may jump out and definitely spark, which is the reason for an.

it looks really Once I had the hole drilled and wires routed (no turning back now), I connected it to a switch so it won't run constantly. So I pulled out my multimeter to check the accuracy, on the gauge it reads 13v, on my multimeter it says There is a voltage of 28 (battery tender voltage) both at the source and on the back side of the gauge. It's not by much, but it's close. During the day, I use it to run auxiliary lights from a car battery that I attach to my tent trailer. Whenever I need to charge my battery, I use it to get an on-the-fly estimate of how much charge I need. As of right now, I haven't checked the second one but I am assuming it will be similar. The only way to know if it will last is to wait. Being off will tell. The difference between 3 volts and 3 volts won't be a problem since the measurement is under. Is it likely that I will My guess is that it won't happen. My attempt at something more accurate will be a dice roll.

I bought them for my service truck so I can easily check the voltage now that Ford has decided that we do not need voltage gauges. I had no problems installing the program. Despite the screen being a little farther back than expected, I checked the accuracy with a voltmeter and it was off by This is not a problem since it is only 2 volts.

A battery from my boat was hooked up to them. You will need two batteries, one for the trolling motor and one for the main motor. I like how they light up nicely and how easy it is to read them. It brings me great joy to be able to keep track of my voltage at all times. According to their description, they do work.

I wanted to know the status of the tractor's battery &ampampamp amp The golf cart also endured the vibration and abuse of the big diesel engine and has been a reliable sports car for many years. There is only a little engine on the These have so far proven to be very good.

It rained throughout the day while I worked. This was followed by an error message. The unit worked until the next rain after it was unplugged and replugged. Afterward, the voltage registered half the original amount (mounted on a voltmeter for verification). I am not able to.

This is an extremely bright light source. But the display shows all eights if the input is not powered and when new, may be confused with a plastic protective An attempt was made to remove an unexistent covering, but it left scratches.
