This is ideal for use in split charging or in a variety of automotive applications.

Questions & Answers

Does it take a certain amount of voltage to connect a circuit?

This trigger requires 12 V, but the maximum voltage is 14 V, and the maximum amperage is 150 milliamps. This may be of some use to you.

How do you put this on a continuous loop?

There is a continuous duty on this heavy duty relay.

I want to use this to charge a second battery in my 4 wheeler with a 60 amp alternator. Can I turn it on and off to recharge it?

It is important to connect the stud and nut terminal 30 to one battery and 87 to the other, 85 and 86 to a ground and a 12 to turn the power

Although inconsistent, after a bit of reworking it is acceptable for the price
3/5

The same item was bought twice. As soon as I clicked on one at 11, I noticed another at 12. One is powered by 5V, the other by 6V. The gap between the lights and the light switch had to be adjusted as I didn't want them to light up until 12. There were two posts with coil ends that were crimped on to the coil ends of one coil that were horribly misaligned. Other wires were aligned properly, the coil wires were soldered to the posts, one was crimped, one had solder filling the gap, but the other were left unsoldered. On one end, there is a copper bar connected to terminal 30, while on the other end, there is a chrome plated brass bar with additional surface area for heat dissipation? The contacts do have a very small amount of silver on them, which is good. Once the coil wires are soldered and some epoxy is added to the coil, the relay looks decent for the price. One thing I don't like is that the relay base is not thermal set plastic, which may melt if a terminal gets too hot, shorting it.

Relays bigger than any you've ever seen before
4/5

The size may be twice as large. A removable bottom makes it easy to mount and wire the device. I hooked it up to a 10 fuse holder and wired it up to the As of now, I have 10 connections that need to be hooked up to the ignition system. There is no need to tap into the Finished putting the fuse tap on the relay and hooked it up to it.

A nice heavy duty relay at a reasonable price
5/5

It came in handy for a solar water heater project. I ran a DC element in the tank with power from PV panels. Solar panels are powered by red #8 wires that go to the element via the relay. A 12VDC transformer (wall wart) was used to run a small amount of power through the thermostat on the water heater and then through the relay so the thermostat setting would control the relay, allowing power to flow from the roof panels to the DC element and allow the water to be heated. Thermostats normally found in water heaters are not designed for DC and will burn up the contacts within a short period of time. The relay is rated at 120 amps I will ignore it) which is way overkill for the 20-inch screen Probably 30amps or so from the panels will be sent to this element, so this should last quite a while.

I'm really impressed with this It was imperative I fit a 12v relay to the enormous cooling fan in my project car since it drew a good deal of power
5/5

There were other relays that were rated for amps but yet melted around the contacts, which was not encouraging for I'm very pleased with this relay because it has a great feel and is built well. The lugs on it allow large gauge wire connectors to be screwed on, and the wire connector itself is heavy and bulky. My favorite part of it is the music.

Relay is great for heavy duty work
5/5

For my Sprinter van, I bought this relay to use with my sine wave inverter. Six of my connections were successful This switch works perfectly with 14 gauge wire for the switching part and gauge wire for the wire going to it.

The product is of good quality The product works just like it says it does
5/5

Using it as a relay I was able to- A windshield washer fluid heater is off to the rescue. During the summer, I won't need it so I simply turn off the heater with the relay, unless I need it for a bug attack. I love the juice!
It works just fine.

That's what I told you to do! I use this to feed my car auxiliary electric circuit, since it includes a bunch of accessories
5/5

Although it is intended for marine use, I use it for my car. This relay helped me increase the power up to 100A, so I'm very pleased with it! In a short time there was no overheating even at the top capacity, the terminals remain fresh, so I'm happy!.
