    check the voltage at the battery after starting. you may have a voltage reg/rectif going out.

    think you should see voltage climb after starting to about 13.75v

    post over in the rude/johnson section - include the model/serial number of engine.

    Re: javelin tac not working (javelinbill)

    Is it a system check tach? If it is, does the system check still work?

    The tach on my '99 died last year. I sent it back to Faria this spring and for $50 they sent me a brand new one. If it is a Faria they have a lifetime Warranty and they will fix or replace it.

    94 model will not have system check unless he has changed motors. I would say you have a bad Rectifier/Regulator!
