Re: humminbird wide 100
An owners manual will not help much. It only covers the operations.<br /><br />Look for high or low voltage on your power supply line.<br /><br />Look for damage, kink, smash, or pinch, in the wires that run to the transducer.<br /><br />Cheaper to replace the whole unit than to try to fix it if its broken. Even a transducer and cable will cost you $50.
