      Multi meter > 10A DC ???

      Been looking for a new multi meter. My old Shack one died after 20+ years. But I'm having a hard time finding a meter that measures DC current of more than 10A. Even the analog meters I seem to find locally only do 10A DC. Any suggestions ???

      For more than 10 amps you will likely have to go with a clamp on style ammeter function on the multimeter. Lots of them on ebay. Clamp on is much easier than connecting your ammeter in series with the load.

      I've got a 20A capable one. Picked it up at Radio Shack.

      Scored a new Milwaukee 2239-21 M12 off of ebay as a one day cyber sale for $59.99 shipped free. These sell for $399.00 at Home Depot. The sellers normal price is $259.00. Seller had a 99.7% rating on 130k+ feedbacks so I hope it's as described.

      I have a Columbia Electric Mfg. Tong Test "clamp" style gage here at work that I use to calibrate/verify our welding machines with and it has three heads that go with it...0a-50a, 0a-200a, and 0a-500a. It measures A/C or D/C current.
      1970 RS/SS350 139K on the clock:
      89 TPI motor w/ 1pc rear seal coupled to a Viper T56 via Mcleod's modular bellhousing w/ hydraulic T/O bearing from the Viper, 12 bolt rear w/ 3.73 gearing, SC&C upper control arms, factory lowers with Delalums, C5 brakes at all four corners, Front Wheels 17x8's with Sumi 255/40/17 and Rear Wheels 17x9's with Sumi 275/40/17.

      Ideal makes a relatively inexpensive AC/DC volt/ampmeter #61-768 for about $170.00. It's a straight VA, it doesn't read impedance, so if you need to have one that does, Then you want 61-765 GA, but your looking at a little more money, probably about $80 more. If you're a serious auto electonics guy you need a Fluke 88V/A, but it's an easy $650.00 & you still need a separate amp clamp to do above 10 DCA.

      I see you bought a new meter but before you toss the old one open it up and see if there's a fuse you blew. I've blown the fuses in Radio Shack meters and just go get a new fuse.

      Thanks. I did that. It looked like a combination of things. Looked like a few blown components and battery leakage. It was almost 20 years old. It led a good life

      too bad you found one so cheap I have a Mac version of the OTC Perception and could have possibly sourced a low amps clamp also and it is for sale for $400 obo AND it also have single cylinder ignition capabilities.
      But oh well at least you got something to hopefully get you going.
