Rpm gauges stopped working
 

Well today installing the radiator and after everything was installed the rpm gauge wasn't working at all. Oil gauge seem to be acting a bit strange.but the oil gauge could've my pump I been thinking of replacing. Only reasoning think the rpm gauge isn't working is when going to test the radiator out and filling it up the water hose got turned on to high. Mainly the passanger getting extra wet, so is there a connector/fuse that could got wet causing the rpm gauge not to work. Any assistance would be nice, kinda scared the crap out of me when noticed it when firing the car up.
