Default Re: Lazy Ammeter

You can put the 'snap' back in your ammeter by touching and stroking, from end to end, the old, tired magnet ring with a really powerful little nodym.. neodim.. rare earth magnet. Do it several dozen times. If you have an old computer hard drive to take apart you will find a good super-powerful neodymium magnet in there.

There are adjusting tabs or wings on the needle movement. Put it in series with a quality meter and about a 10 amp load. Best to adjust it mid-range.
