The math is simple: 350- 200=150amps over, which is nearly a fourth of the alternator's maximum power.
A battery selector switch can be found on most boats. There are three different types of batteries: one, two, and both. If you don't have a selector switch, you can use this to charge both batteries while the engine is running, but with the engine off, you can draw down one (stereo, trolling motor, etc.) without affecting your ability to start with the other. Your system's operation will be determined by how the batteries are wired (in parallel). To use this relay, the system must be split into two parts, for example, one house battery and one starting battery. If you remember to turn on the manual switch, you'll have more control over your system.
There is no answer because there is no question mark. There are no answers. The gadget is a relay, and it has a 12-volt power supply. The only constant heat producer is the volt coil, which can be powered by 12-volt batteries. volts, it shouldn't produce a lot of heat. The maximum capacity is 80 people. The relay contacts and connections have a maximum current rating of amps; exceeding or maintaining this rating on a continuous basis may cause heat to build up. It's possible that the device will get warm from the environment if it's mounted near the engine or in the sun. What is "in" these days. " Have you double-checked that all of the connections are secure? Is the load approaching the maximum of 80? amps? Is it possible that the coil is seeing more than 12 volts? volts? Is it true that the wires are involved in the 80-year-old case? Is the current-carrying capacity of the amp circuit sufficient? It's also possible that your device isn't working properly.
Yes. When the engine is turned off, the device properly installed separates the main and auxiliary batteries. Both batteries are charged when the light is turned on.

The continuous current rating of the contactor is 80 amps. There is, however, no mention of power factor requirements - if any - because of the weights It's more of a heavy-duty SPST relay than a true battery isolator. It doesn't keep track of battery voltage and cut off loads before the battery deteriorates to the point where it's no longer safe to use. By the way, here's a combiner/isolator that actually prevents overcharging from causing battery damage. letting go: brings us to yet another piece of information that is still missing - current drawn by the coil in a steady state. That number is something I can check on my bench power supply. When the contactor is activated with a typical automotive voltage of 13, it is at room temperature. It uses nearly 500 milliamps at 5 volts dc - about 6- 0. 5 watts That seemed excessive, so I decided to see if the coil current could heat up the relay on its own. It did. By a factor of a hundred degrees Fahrenheit! The relay body is running at a comfortable 168 degrees F (75 degrees C) in the second photo. Temperature: 6°C Keep in mind that there is no current flowing through the main contacts, which would result in even more heat. br>br>This device has a good rating on Amazon and should be adequate for occasional use, such as switching a small starter motor. Not so much as a load disconnect relay for continuous duty loads. It will be returned to Amazon. For the complete lack of specifications, three stars are awarded.
On January 11, 2018, I purchased this. Everything went smoothly during the installation. One of the terminals stripped far too easily when I tried to tighten the connections. I removed the washers and was able to obtain sufficient threads to complete the connection. For a year and two days, it worked perfectly. With temperatures ranging from - to -, it's been a long time since I've been outside. The relay would not work at temperatures of 7 to 8 degrees - It had become ice cold. For 15 minutes, I'd need to use a heat gun. It would revert to normal after 20 seconds. This occurred three times in a row. I contacted the manufacturer (Stinger) directly and was told there was nothing they could do because the product was no longer under warranty. Be careful who you buy from.
First and foremost, I'm using this relay to boost the amount of power I can get from my car's ignition sense circuit. br>br>Depending on how you set it up, this is unlikely to be a large enough isolator for a dual battery system. This should work fine if your aux/2nd battery only powers extra devices and the crank battery still powers all of your car's stock components; however, if your isolator interrupts the crank battery and the 2nd one powers everything while the car is off, this is not the one for you. br>br>As a few people have pointed out, this relay gets quite hot just by being turned on, which makes me wonder if the coils have too low a resistance, and if I could add a resistor to it to reduce the power consumption at the expense of a higher minimum voltage to engage. It's worth considering. Furthermore, due to their proximity to the body of the relay and the small divider between them (presumably to prevent a short circuit, but you should have a fuse to prevent any damage from that anyways), the coil terminals (the ones you power to engage the relay) are relatively difficult to tighten/loosen. Overall, it's a passable relay. br>br> It does the job, but it could have been much better if a little more thought had gone into the design. If I had known this ahead of time, I would have spent only $12.
This is my second relay; the first worked fine, and the second reached 150 degrees F after being run without a load and only the contact energized. br>After 15 minutes, I got into my van. I couldn't touch it for 20 minutes because all I had was a USB charger. br>Once again, there is a lack of quality assurance. Unfortunately, I was unable to return it because I had misplaced my window. I'll give them a call to see if they offer a warranty on their product.
I bought this for an accessory fuse block on my side by side because I'm a stinger fan and they've never let me down before. Until the temperature drops below ten degrees, the relay is fine. It will not move if the angle is greater than 15 degrees. It's useless if you can't rely on it to function properly.
It works exactly as described and is an excellent value for the price! I also included a diode-based circuit. If one of my batteries dies, I can use the isolated "manual override" switch to jump start my generator from the chassis battery or jump start my engine from my house battery in an emergency. In addition, I have a third diode-based device. When the motorhome's engine is running, I have an isolated trigger from my ignition that allows me to charge my house battery from the alternator. The product arrived on time and in excellent condition. With this one, you can be sure you're getting a good deal.
This isolator, along with a second battery, was installed in my trunk. While the vehicle is turned off, the isolator ensures that both batteries are connected. If they were, I'd have two dead batteries at the end of the day. Using a DMM, you can check that your connections are correct. Check the voltage of the front and then the rear batteries while the car is turned off. It is expected that the outcomes will differ. However, do the same check when you start the car. The two batteries will have the same voltage. br>br>From the front battery to the Stinger Circuit Breaker (inline fuse) to the trunk isolator. A second Stinger Circuit Breaker will be connected to the other terminal. The positive side of my second battery is then connected to this. Two more connections have been added to the isolator. One goes to the ground, while the other can go to any number of places. With the help of add-a-fuse, I was able to connect it to my fuse panel. circuit.
Before even trying to install, I gave up. It needs to be installed in a specific way, and I wasn't willing to open my steering wheel cluster to do so (as the diagram suggests). The seals had already been broken, so it appears that the person who received the product before me had the same idea. br>Before purchasing this item, look up the wiring diagram.
