Harvey, So are you saying if I hook up the meter like this it will blow the fuse every time? I just went and bought fuses but haven't started a new batch of cs yet. Found out they are proud of those fuses here in central TX. Almost $8.00 for 5. I don't want to blow them if I can get out of it. Also got the resistor like Mike said.
