Re: 1992 evinrude 50hp exrnli clicking
battery been load tested and charged up to 12.65 volts?
You only need one jumper cable for the above test, battery (+) to starter positive terminal. Alternatively, get yourself a multimeter and measure the voltage at the starter (+) terminal while somebody turns the key over to "start" - if you get within half a volt or so of the battery voltage, the starter is faulty.
Bad voltage at starter (with clean tight connections), measure the voltage at the solenoid small terminal with the yellow/red wire with the key turned over to "start" you should read within a half-volt of battery voltage, otherwise you have a wiring fault beween the keyswitch & solenoid. Good voltage at solenoid but bad voltage at starter means faulty solenoid.
