What does the jumper do?
1515707
The jumper enables you to isolate the relay control circuit from the coil (The relay has optical isolation when the jumper is removed). If you remove the jumper you'll need to provide power to the coil separately. This is useful if the device that is controlling the relay can't provide enough current (or voltage) to drive the coils.I have a short video of the relay in operation in my review (http://www.amazon.com/gp/review/R2AZD0UTXMKUD1/ref=cm_cr_pr_rvw_ttl?ie=UTF8&ASIN;=B0057OC6D8) - Unfortunately I don't show the jumper in use though.

Robert, that jumper is to allow the relay to work if your driving voltage isn't 5V. For example, my Beaglebone only sends 3.3V.Please read the great comment by Jon Agnew on February 17, 2013 that describes how to support 3.3V micro-controllers. In this case, you have to remove the jumper.

I do not know what you mean by H/L jumpers. I didn't have any problems setting up the device. It works well for my purposes.

The mini jump-it comes with one, but the jump-it does not come with one. It is sold separately

No. I believe what you're looking for is more commonly referred to as a jumper.

Its basically a detector for a in electric magnetic fields. Just turn it on and walk around your home where you have different electric devices. Try around a power box, don't touch it!..you will see a jump on the meter. If you are looking for spirits you may see a spike in certain areas. Hope this helps.

Yes there is a lot of jumping. Look up the program on you tube you will be able to see a few short clips

Yes it does. It quick charges, slow charges and is an excellent jump box. Its real easy to use as well.

I'm nit sure what you are referring to with "jumpboard/rebounder". It has built in resistant bands to add extra fitness development.

no I did not use any jumpers .I just took it the hard drive out of the box then I took the screws off of the old one and put them one the new one and used the sata cord that was already in the computer and hooked it all up and it worked . I would check the Bios to see if it will detect the drive.

It has a little give, I lift weights (squats, deadlift, overhead press) on it in socks and it is comfortable. I think it would be OK for jumping, but haven't tried it. Also, FYI, it has a very strong rubber smell, at least initially. I use it outside and it's OK, but inside the smell may be strong for a while.

It's actually correct and safer for the negative cable to be attached to a strong ground on the car as opposed to being connected directly to the battery's negative terminal. (This is how to properly connect jumper cables to the auto your jumping, as well. Most do not do this or are not aware.)

The jumper is just below the white power plugin. I had problems with this unit---got refunded... I upgraded my motherboard to sata...

This unit has an On-Off switch that controls power to the Clamps. This is a nice safety feature for jump starting and when the unit is in storage. We've added some images to show the switch more clearly.

the black jumper is part of the power system (-), you must complete the ckt. from the ESC to PCB

IIRC it does, the jump starting option draws a lot of power. I'll check mine when I'm in the garage and if it's different I'll let you know.

Yes - be sure it's not going to move and scare him, though, when he takes the leap!

There were no extra parts in the box, nor a mention of it in the instructions, so I would say no, this particular one doesn't convert to a doorway jumper.
