want to check what amps are used when when switch is off and battery still goes dead

This is a simple Volt Ohm Meter. It works, and was quite cheap. I use it for small projects like testing battery status, but it might work fine for your task. Obviously there are many available at Amazon that are of much higher quality, but the price will be more. I would expect you should be able to test areas of your circuit to see where current is still being applied when the switch is off. Do take notice of the ratings for what it can handle.

Disconnect the B+ terminal.Put the meter in DC Amps, Red wire to B+ and black wire to the Battery terminal.Now you have the Amp meter in series with the drain on the battery.Those numbers wont help you find the drain. Start disconnecting things till that Drain goes away.

It'll measure up to 10 amps. Don't forget to plug the red volt meter wire into the current plug AND put it on the 10 amp range. If you get the wire polarity backwards, the volt meter will just show negative number. You won't blow anything up. However, do remember to move the red wire back to the voltage & resistance reading plug. Forget and you could have a problem the next time you try and read a voltage.Also be looking at the meter reading when you hook it up, if it goes over range disconnect immediately.

Check your connection and battery. Also check that the switch is in the correct position.

I've been using AA batteries, but there is a power input on the unit labeled DC 4.5v

Whatever amps car key switch give works great to start most big relays Use a battery charger to start it, that should show the amp draw

Buy a P3 P4400 Kill A Watt meter......they're about 19 bucks and will tell you exactly how much power its using

Measure it with a voltmeter. Or use a battery tester. You can get a multimeter (measures volts, amps and ohms) for as little as $15. Then have someone show you how to use it. Its not hard and it's fun. Many other uses such as checking continuity, troubleshooting your car, checking electrical sockets, etc.

The only suggestion that I can make is to trace all the wires and make sure that all the connections are tight. If the battery is fully charged it can only be a loose wire someplace or a defective switch.

The sure way to tell is to use a circuit tester, such as an Ohm meter. This way you can check the drum machine end of the cords for continuity, when switching buttons off & on.

Hook it up to the battery you want to test and select test. The tester will test the battery ans tell you if it is good or bad,

Doito, went dead, no LED light indicates to me that your batter is nolonger connected, Check to make sure it has not disconnected, make sure it's not bad. Even new batteries are bad out of the box. I experienced this first hand as an electronics tech

not sure, i use to turn on/off a 9volt battery. Im not technically an electronic master. Sorry man.

The battery died because a cable was plugged into the unit. It doesn't matter whether the connection made it to an amp. The circuit is "turned on" when you insert the 1/4 plug. Many players remove the cable between sets to conserve.

Sorry, haven't a clue. I've not even tried mine, just wanted something to test batteries before purchasing them unnecessarily.

You can hook direct off battery if that is easier for you, the small amp draw would be no drain on battery. Make sure you have a on/ off switch. It would be recommended to install a fusible link in the live wire, you can buy these links anywhere automotive acc are sold. Just a length of wire wirh a spot to insert say a 15 amp square fuse.

There's an Off, 3V, 4.5V, 6V, 7.5V, 9V and 12V on the switch. 2000mA max current. Works great to power my XM boom box on my boat!

I don't have one, sorry. Look in your manual, all you have to do is match the voltage and amps. I don't have my original one either.

Why would you want to? Switch off (open circuit an remove power) is the same as a power outage. Light would come on until battery dies.
