Multimeter Help
sr71p38:
I am not an electrical guy but I am very confused about something and I hope the community can help. I am trying to get my multimeter to read the amps out of my wind generator. I have done a bunch of online research and I can't seem to get it to work. I am sure it is something very simple but I am at a loss.
I have placed the multimeter in line with the generator and the battery, I have even tried to put in a 10ohm resister at one point in-line and took out the bridge rectifier. No matter what I do I can't get an amp reading with the multimeter. I have tried both meters I have as well, thinking maybe something was wrong with my meter.
I can get a voltage with the meter. I have a bayite DC 6.5-100V 0-100A LCD Display Digital Current Voltage Power Energy Meter Multimeter Ammeter Voltmeter with 100A Current Shunt which when I hook it up I get all the necessary readings I just don't believe them.

I have pretty much the same meter. Are you sure your turbine is producing amps? Do you have all 4 wires hooked up in their correct places? Is the shunt on the battery side of the rectifier in the negative line? Did you try the 2 shunt sensor wires both ways? It can be unclear which one goes where i think.

Thanks for getting back to me. I am getting a reading when I use the Bayite, I am just not currently sure it is correct in the Watt and Amps it is showing. It seems really low. I was trying to run a test to verify that it was showing the correct information by hooking a multimeter up and I get nothing from it when I set it to Amps.

David, what are you using for a load, and what is the resistance of the load?
It is also possible that the fuse in your multimeter/ammeter is blown.

I was using the battery which is a 24volt battery. I then used a 10ohm resistor. The output from the generator at 1000rpm is supposed tob be 0.5amps. I thought about the fuse, I need to pull the meter back apart to check but since I was not using the millamp port I didn't think it should matter.
