If I keep the coil always energized, will it fail very soon?

If the coil is kept cool it well last a long time. The coil is uses a small (low)amount of current to energize and close the points in the relay. The point carry the high current output. High Current(AMPS) Draw produces heat.

I run headlights with 100 watt h4 bulbs, electric fans, and fuel pumps with them they haven't failed yet... keep some spares just in case and make sure they do not exceed the amp ratings.

The following post is from ehow. This should help with your question. http://www.ehow.com/facts_7845078_long-ignition-coils-cars-last.htmlFederal law in the United States dictates that the ignition coil and ignition module on new vehicles are warranted for at least two years or 24,000 miles, whichever occurs first. The insulation in the ignition coil will degrade over time, but many coils are designed to last 100,000 miles or more.

It should last as long as any other relay that stays energized. Cars use them all day every day without fail so I would say no. I don't know what your planned use is but a relays' function is to control (turn on or off) a high amperage circuit through the use of a low amp circuit. Hope this helps,

Hard to answer without destructive testing on the device over many years. I have had these installed in my house for over 3 years now and not one has failed nor have I had any device damaged due to electrical issues. Hope that helps.

Yes, that would be fine.Because I left mine plugged up since the day I got it, and the green and the red lights are malfunctioning.If you leave it plugged up, chances are it could fry.

I wouldn't. You are over the amperage load it was designed for. You will get a lot of heat and early failure in your best case scenario.

Mine has been fine. Had it a year and a half almost always plugged in and still lasts several hours whenever I unplug it. Ran it about 5 hours unplugged the other day and it was still going strong before I had to turn it off for the evening.

It would for a short time and quickly burn out. It is rated at 4 ohms, below that would damage the amp

As far as I know it should not hurt: I have the 7500 watt Generac and leave my charger always plugged in - have for several years with no ill effect.

I'll be honest. I have never had a battery failure. When used frequently, here and there it usually takes a month for them to wear down. It is a non-issue for the convenience of no wires!

I have been using the power supply for a few months. The unit operates well. But it has problem with heat sinking. The unit has a finned heat exchanger to dissipate the heat but the power will cycle on / off because of the temperature rise due to inadequate natural heat convection. If you want the unit to operate all the time, you need an external fan to blow air on the finned exchanged. I hope this is helpful to you. Regards, Ram

Hard to tell but depends a lot on the ventilation. If open to the air it should last its full claimed life. If totally enclosed then it will probably overheat and fail early. Really it all depends on the installation

I've had mine for a year or more and always keep the power connected. I have never had a problem.

If you draw too much current, it will blow the fuse. Otherwise it should run indefinitely.

I do not know. You can be the one to test the idea. If your V U meter (probes contacting the power input) reads a current as you spin the prop reverse of its normal direction, then yes. If it breaks then no.

This is a very common problem with small generators. I have 4 UPS's and none will stay on line. The frequency on my generaror is too high (62-64) and I assume this is the problem as the voltage is fairly constant. One day when I have lots of energy I will attempt to adjust the throttle linkage as the frequency is directed linked to engine speed.

Yes, no problem. Recommended so you don't run out. I keep it plugged in when using.

I always do but I think if you ride a couple of times a week you should be fine. The green led does not pull much power. That being said I would not leave it plugged for two weeks straight. Hope that helps.Charles

It failed after about a month. I had it plugged in all the time. It was under warranty, but the manufacturer required me to pay for shipping PLUS SIX DOLLARS handling!! I through it away and got another brand at Home Depot. good luck..
