On my Johnson 50 (yr 2000)my tachometer is operating very irratically. At high throttle it does not read more than 1000 rpm.<br />Can anyone tell me how to troubleshoot? <br />Someone has told me that if the engine is not generating, than the tach does not function well. <br />How do I tell if the engine is generating? ((No ammeter on board) :confused:

Buy a $10.00 AC/DC voltmeter from a hardware/auto supply store. Perhaps, you already have one.<br /><br />Put the red terminal on the + term. of the battery, the black on the - term, of the battery.<br /><br />Record the voltage.<br /><br />While running, the voltmeter should read above base batt. voltage, if it is charging.
