Review: I purchased this product because I needed a continuous duty solenoid to keep two 12v batteries wired in parallel charged while driving the vehicle but not engaged while the engine is off, so my engine battery would not lose its charge because of the two house batteries draining it without my knowledge. It took some time to install the system and get my Chevy cargo van ready for some distance camping. But even before I left town, I discovered that the solenoid was getting hotter than I could even touch and my automatic breaker kept cycling. The odd thing was that I didn't have my inverter turned on nor any of my inside lighting (which wouldn't have been much). The only thing that was going on was the solenoid providing power from the alternator to keep the two house batteries charged. Nothing on the device indicates it's a continuous duty device and nothing on the device indicates the rated amperage. I'm quite disappointed that the device I purchased didn't even last for a single camping trip but gave me enough unrest, over perhaps suddenly bursting into flames, that I disconnected the device. And since I purchased the device June of 2019 and it's now August of 2020, I can't even return it for a refund. So, it's a total bust and I would caution other buyers to be aware and make certain you thoroughly check it out before getting into a desolate area and finding that it's just not what it should be.

## Questions & Answers

**Q: Description says 300a continuous but in the lower info it states note: normally make 80a as working current, need break 5 sec on, 50 min off  - why???**
A: This is MaySpare  Service. The Max Short Time Current can endure 300A; But if u want to keep working for more than one hour without break, the current need be about 80Amp; Otherwise the body of solenoid will be so hot and burned

**Q: How many miliamps does it require to activate the solenoid?   I want to make sure my momentary push button switch can support activation of this solen**
A: I believe the coil resistance is around 14 ohms which would make the current around 900 milliamps.  But Rember thr collaspe of the coil during disconnect creates large spikes across a small switch and burn the switch contacts, therefore I would a 1 amp @600 volt despising diode across the solenoid coil to protect your switch contacts.

**Q: None of the posts are labeled. Which one is the on switch?**
A: This is generally used to power large loads like a starter or like my app. Four bilge blowers. 
The big posts on the side are battery cable in than wires out to the load. 
The small posts are power and ground to run the solenoid. Connect one to ground one to the switch. 
You might want to test the small posts with an ohm meter. Make sure neither is to ground .

**Q: why is his thing getting so hot?**
A: Give me some background info, how many amps drawn ,voltage and application

*by D***E on 4 March 2020*

For all you Golf Cart riders. I normally do not write reviews, but when its necessary to prevent accident or harm, then I find myself doing the right thing and writing one. I have a 2017 Yamaha G29/ drive electric golf cart. I installed this solenoid hoping for better performance. Pretty easy to install. After installation, I gave it the test ride. The solenoid had a loud click when mashing the gas to engage it, which my old one did not. J hunt from my cart, so this was a negative. I headed down the road to neighbors house which is 600 feet one way, I know exactly, because I built the fence that runs parallel with the test ride, the cart did not perform any better. I turned around at my neighbors and came back another 600 feet, 1200 total. Pulled up at my shop, went to feel of the solenoid and it was way over 300 F. I could not even touch it. I left my cart sitting for a while and used pliers to hold the solenoid while I unwired it to remove it from cart. I would be scared to death to run this thing frequently on a golf cart and park the cart in your carport, shop per say. It might very well burn it to the ground. I really wished it had worked, but it didnt.
