1972 evinrude 85 hp, no start

[phatmanmike]

my motor started fine yesterday, but at first it seemed like it would only"click" and not turn over, now today, im playing on it in the front yard and now it clicks sometimes and other times does nothing, i know its electrical related..but, when the key is on , the starter is getting voltage, i checked that, and the selinoid is getting voltage, and the electric shift is getting volatge, so what else is there, its old 1972 what else does this thing have

If you're for sure getting 12vdc at the starter and it's not spinning, the the starter is bad.<br /><br />c/6<br />Hooty

Outboard Wont Start: <br /><br />1. Electric start: Does the starter engage and rotate the flywheel at a good (normal) speed? If yes, go to 2. <br /><br />* Does starter spin, but bendix gear (small gear on starter shaft) does not engage the flywheel? Lubricate bendix spiral shaft. <br /><br />* Does the solenoid click? <br /><br />* If yes, measure voltage at the starter terminal to battery ground with starter engaged. <br /><br />* If 12 V, repair or replace starter.<br /><br />* If less than 9V measure voltage at large solenoid input terminal (from battery). <br /><br />* If less than 9V, go to 3. If 12V, replace solenoid.<br /><br />* Solenoid does not click when key is turned to start. Measure voltage at small solenoid terminal. <br /><br />* 0 volts? Troubleshoot kill switch (lanyard connected?), battery, starter switch and neutral start switch in controller. <br /><br />* 12 volts? Replace solenoid.<br /><br />2. Flywheel rotates but engine does not attempt to start. Electric and manual start.<br /><br />* Remove a spark plug, reconnect it and hold it against engine block. Does it make a hot, blue spark when attempting to start? If no, troubleshoot ignition system.<br /><br />* Has hot, blue spark. Squirt some fuel mix (NOT ether) into the carb(s). Does it attempt to start? <br /><br />* If yes, you have inadequate fuel. Troubleshoot fuel system and review starting procedure. <br /><br />* If no, check that carb is not flooding from failed float needle.<br /><br />* Still wont attempt to start. Check compression. If bad, troubleshoot mechanicals.<br /><br />* Good compression on all cylinders. Check flywheel for sheared key, check crankcase for sealing at carb(s), inlet manifold and bypass covers.<br /><br />3. Low voltage at starter when engaged. <br /><br />* Measure voltage at battery terminals. If below 12.6 volts with all electrics turned off, recharge or replace battery. <br /><br />* Measure battery voltage with starter engaged. If below 9 volts, recharge or replace battery.<br /><br />* Remove and clean connections on battery-to-solenoid cable, battery-to-engine block cable and solenoid-to-starter cable. While they are off, inspect each for corrosion, broken insulation with corrosion and weak points. Replace corroded or weak cables.<br /><br />* If problem persists, remove starter and clean all surfaces where engine block and starter connect.

Re: 1972 evinrude 85 hp, no start

thanks guys, here the deal...i have 12.8 volts at battery with my voltmeter, i have 12.8 volts at top of selenoid, i have 3 volts at the bottom of selenoid, so i replaced the selenoid... now as for the two lil connectors on the selenoid, i know one is the ignition wire from the key, but what is the other, .. anything? i ask all of this simply because my seloc 1968-1972 evinrude manual hasn't arrived yet, just ordered it friday, so... you are my only hope ! till then

The one small post (terminal) is to the start position on the ignition switch. The other small post is to ground.<br /><br />c/6<br />Hooty
