Re: Pinion wheel won't engage the fly wheel and its a sunny day!
Ahoy, Goldenboy. <br /><br />Do what RL29 suggests. If that doesn't work, go back to what your manual says.<br /><br />The electric circuit that runs your starter motor (High Current circuit) behaves very differently than low current circuits or high voltage circuits. Resistance built up in an imperfect connection that your ohmmeter wont notice can prevent your starter from running, or slow it down so much it can't engage the Bendix.<br /><br />Remember Ohms Law from high school Physics? E=IR, R=E/I and, important here, I=E/R. The current to the starter motor will be equal to the voltage (12v) divided by the total ohms of resistance in the circuit.<br /><br />To get the several hundred amps of current needed to make your starter work properly, the total resistance of: the + post connection on your battery, the connection of that cable to the starter sonenoid, the contacts in the solenoid, the connection of the solenoid output cable to the solenoid, the cable connection to the starter motor, the brushes in the motor, the motor mount to the block, the ground cable connection to the block, the ground cable connection to the - post of the battery and all of those big wires involved (ALL) must add up to only a small fraction of 1 ohm. <br /><br />One corroded connection and no starter. <br /><br />A common trouble is a little corrosion on a connection or a corroded cable.Take them all off and clean them carefully. When you put them back, spray a bit of WD-40 on them to keep more corrosion out. In my experience, the ground cable connection to the block is the most common place for this to happen on OMC li'l loopers.<br /><br /><br />If that doesn't fix the problem, either the solenoid could have worn out or your starter needs brushes. Don't let anyone sell you a new starter. Hold out for brushes.<br /><br />Let us know how it comes out.<br /><br />Red sky at night. . .<br />JB
