fit right in and hooked up easy on my 12v 42 slat grill willys.

Works fine – light is nice and bright, dimmable on the lights rheostat, ordered a second to match this one – I have two gauges in my old RV, one for the engine battery (this new one) and one for the two coach batteries. At 16 bucks and free shipping, what’s not to like. Tried to buy at my local retailer, both places I checked were out of stock and could not promise before the weekend.

this volt meter was taken apart and adapted to fit into a 51 chevy truck gauge cluster to replace a amp gauge then checked against a multimeter and works perfect not the normal way its used but i wanted a volt meter not an amp meter in the old truck so i would not need to run a 10 ga wire other than my use for it its a great gauge for the price

Junk, does not work right out of package, Had it for over 30 days before hooking it up. Doesn’t work, can’t return it. Money wasted. Go to NAPA and buy.

Bought this voltmeter to replace a useless ammeter type gauge in my ’68 Bronco. Good looking, good directions and easy to install. No need to order an underdash bracket to hold the gauge, it comes with one. Works great.

This Sunpro CP8215 Styleline voltmeter, as expected, is simple to install and works well. The needle gives instant response and clearly has no mechanism to mute its movement – this undamped design might limit its lifespan. The instructions do not mention if there should be a fuse in the circuit so I added an ATO 1 amp to the positive side. Satisfactory so far.

This voltmeter has zero mechanical damping, which means that, unlike many other similar instruments, the needle appears to be constantly vibrating as it responds to every slight change in vehicle voltage. This makes it hard to read, and that’s a pity because its a nice looking instrument with a clear scale that is particularly well illuminated.

Since originally writing this review I had forgotten how much I hated the Sunpro’s jumpy behavior until I needed a voltmeter to temporarily fit to a friend’s car. I pulled this one out of its now dusty box and once again found it almost impossible to read because its indicating needle was bouncing around so much.
I also checked it against a digital meter, which I know to be very accurate. As was the case with another reviewer’s voltmeter, my example read low. However, I happened to look down the hole into which the illumination bulb goes, and there is an adjustment potentiometer down there. A small instrument screwdriver is needed to adjust it and it is almost impossible to access the potentiometer slot without also touching the sides of the tube into which the bulb holder is normally installed. As this is an electronic meter, and I was unsure what the effect of shorting the metal of the adjuster to the metal of the instrument case might be, I removed power first. Alternatively, I could have insulated the shaft of the screwdriver with tape or heat-shrink tubing. Counter intuitively, turning the potentiometer counter-clockwise INCREASES the meter reading. Using this method, I ended up with an accurate meter when it is connected to a clean supply, as is the case when the engine isn’t running and the voltmeter simply measures battery voltage.
A commentator on my review suggested using a capacitor to smooth out the voltage being read from the rectified and un-smoothed alternator. That wouldn’t work without also having a some series resistance, so I decided to experiment using a cap and resistor. I used a 1500 microfarad, 20V cap connected across the meter terminals. This size cap will always be an electrolytic type, and it is necessary to ensure that it is connected so that its negative side goes to ground and its positive side toward power. I then fed the power to the meter and cap via a 15 ohm, 0.25W resistor. It certainly helped damp the meter movement a lot. I further improved things by adding a diode (1N4001), in series with the resistor, so that the capacitor could only discharge into the relatively high impedance of the meter, rather than back via the resistor and very low impedance of the car’s electrical system. The diode has to be connected with its cathode (indicated by a bar on its body) toward the meter. The resistor drops about 0.5V and if the diode is used too, that drops another 0.6V, so it’s necessary to adjust the meter reading by comparing it to a know accurate meter, as described above. A bigger value capacitor would provide more damping, but the one I used was already physically large at 1.5″ long x 0.5″ diameter. A higher value resistor would also increase damping, but the resulting higher voltage drop may go beyond the available adjustment in the voltmeter.

I thought I would give sun pro gauges a try on my vintage land cruiser after it was recommended to me by a very knowledgeable mechanic friend of mine. He said, for the price it was hard to beat. I installed 4 Sun pro gauges and they worked flawlessly. My voltmeter was accurate and it does have a slight vibration to it but hell, my land cruiser vibrates like an off road vehicle does after 30+ years if use. Out of four gauges, one gauge had a burned out light bulb. But they have proven to be accurate and they look great. In the past I have always used Autometer gauges. Same quality as the lower priced versions of Autometer but 1/3 the cost.
I highly recommend this product.
