Amp meters should not spark because they are not connected internally to ground at all. If they spark it is because they have either an internal fault to ground (internal insulation bad)or a connection is loose or corroded. If you have a Ohm meter, disconnect both sides of the amp meter and see if there is a path to ground between either terminal, and the case of the meter. If there is any reading on the meter (should show the same reading as if the leads were not connected) the meter is bad. Now do the same across the meter terminals this should show no resistance, (meter should swing full scale, or go to 0 (or near 0) ohms. If it has no conduction it is bad, if it reads full swing, or Zero (or near) it is OK. Check those wires for clean shiny ends, and proper size. The wire to the amp meter from the starter relay should be 10 gauge. The wire from the amp gauge to the alternator big terminal should be 10 ga. It needs the light or diode to make things work correctly, do not use it without that feature. (it might work, but it might give un expected results (like not shutting off). Be patient, be thorough, and keep us informed on what is happening. JimN
