I wanted to use this ammeter to replace the one on my sears battery charger,wired it up like the original,but won't work.Am i wiring it wrong?

Maybe. The meter in your charger may use an external shunt, while this meter has a shunt built in. That would definately not work. If the wires to your old meter are thin, that is a hint that an external shut is being used. If you remove your old meter and you can still charge a battery with the meter removed, then you do have an external shunt somewhere in the battery charger.You could splice this meter into the cables coming out of the charger, but you would have to construct it carefully so that there is no exposed wiring. A spark can cause the hydrogen generated by a charging battery to explode. My recommendation is to just buy a new charger Maybe.

You would need to know how the ammeter circuit of your charger. This meter needs to be in series with load.

Yes--- not an issue-- make sure that you purchase one that scales to 10 Amps.. these are terrific units and very inexpensive

Roger, there are only two ways to wire it... if it does not read, simply unplug the unit 110 volts and reverse the two wires.

I wouldn't think it matters at all. I have never seen this low a rating- are you sure it isn't 3 amp or 2.5amp ? either way is shouldn't matter- there is probably a fuse to insure no overload. BTW- the one I bought seemed to work for 30 seconds and next thing it wasn't supplying any power at all. I never returned it , just used the old one that wasn't really bad. My alarm system needed a new battery and a fuse.

C. A., I use the same charger that came with my lap-tap. Replacing the battery shouldn't have any bearing on the ineffectiveness of your charge cord.

I don't think any clamp-on inductive style ammeter is going to be that accurate. Even the really top end ones are probably +-0.2 amps or so. You need the type that has actual wire connections.

Check your paper work that came with meter. Other than that, I have had no problem with mine. I set it for what I want to check and it works just fine. Your meter and mine are the same.

Try fresh set of batteries as 1st step-What makes u think meter not working?

Less than my clamp-on ammeter would respond to. I'd have to disassemble the circuit and put a series meter in the circuit to find it for certain. If you call the manufacturer they probably could tell you. They do have a web site. Just a guess but I would think it wouldn't be more than about 20 mA at 120VAC.

You betcha Bobby G. The motor units and attachments are essentially the same...only cosmetic differences. I own and use both brands and interchange them without any problems. I do NOT have any of the Sears chargers or batteries, however, if they fit each other, they will work.

I cut the wires and soldered leads to connect straight to my battery lines on my Motorhome since I too did not have a lighter outlet outside on the roof where I mounted it. Just make sure you put positive with positive and neg with neg. it works just fine on mine.

It may be weak batteries. Do you have the a.c. adapter? That may resolve the problem. I am assuming that you are referring to missing segments in the characters, not missing the entire character. Beyond correcting low battery power, I think your meter is due for servicing by a knowledgeable repair person. Have you contacted Omron about the problem? The may provide a replacement depending on the age of the meter.

I just happened to have one that matched the voltage specified on the unit. Try radio shack.

Amy, I can't say that I'm 100% sure it will work for you, but it worked for me. My unit was very old, looked just like this one, and this new part worked perfectly. It was easy to pop out the old one and literally plugged the new one in. If it happens not to work for you, you could send it back?

Would appear that either (1) the battery is no good, (2) the charger is no good, or (3) neither is good. Likely hood is that battery is defunct. If you have a Batteries Plus store near by (maybe a Radio Shack), they should be able to test the battery for you. I purchased a replacement battery on line. Same battery but much lower cost is available on line from different sources. But, you will likely need to cut the adapter plug from your existing battery and solder leads to the new battery.

This didn't happen for me. It could either be a faulty meter, or it is getting 0.0 volts.

Send it back, if its working at all means you wired it right. Probably has a bad timer motor.

Sorry, I can't shed any light on the subject, Brian. After ordering the charger I discovered the problem was with my battery not the charger - I returned the charger I purchased through Amazon. My battery had run too low to be charged using any charger. I had to take it to a golf cart service store and they got it up and running for me. The charger I had was perfectly OK.

Hey man.... just connect it like the instructions tell you. Direct to the positive and negative on the battery. Not part of the charger. Connect and forget and let it do it's thing. Mine has been on my RV battery all winter while I'm staying in it in Arizona. Works by itself. Still have the original battery in my 2008 rig.
