1970 evinrude charging issues.

[seaswirl71]

this engine is 1970 60hp evinrude 60073-d. Motor ran fine this morning went fishing moved twice, went to start it up and move and got very little starter noise, it tried to turn but just barely, the starter is still engaged with the flywheel. I have 11.98 at battery 11.98 at starter soelnoid but when I turn the key im only getting 3.2 at the starter? tried (while on the watr) to jump starter stright from solenoid but I didnt have a big enough wire and it basically melted the jumper wire. thought battery and charge at first but 11.98 is ok I think why only 3.2 at starter? I have a manual but am unsure of where to start. I have looked over the faq.

Start by disconnecting, cleaning and reconnecting all of those big wires in the battery to starter circuit, including the battery ground cable where it bolts to the block. While they are off, check each one for weak spots or corrosion.

Then go to the Top Secret file (top of page) and do the starter circuit voltage drop tests in "Outboard won't start".

You may have a bad solenoid, but it is more likely a high current cable or connection.

well after some reading I went out and tested the battery connection at solenoid 12 at rest but when the key was turned im only getting like 3 or so? would this point towards bad connections? and is 11.98 good for the battery? either way I will be replacing the pos and neg battery cables as they look quite old, but am tryin figure out if its not charging or if something else is wrong, am also going to have battery charged and load tested.

Re: 1970 evinrude starting issues.

so if the battery tests good and i replace the cables I guess the next step would be the charging system? IE rectifier and stator tests? all voltage is dropping when the key is turned down to 3v. but i will test it again after the battery has been charged and load tested. does this point to anything in particular?

Re: 1970 evinrude starting issues.

alright got battery out and cables aren't in the best shape so I will be replacing those. while batt out i tested the rectifier and the stator per my oem manual, got no reading between either yellow wire and ground and got 1.2 ohms between yellow wires ferom stator. book says I should get an infinite reading from yellow to ground i get nothing, says should have .75 ohms +-.2 I am getting 1.2 ...does this mean the stator is bad? ( tried reading in every ohm spot on meter). i am having batt charged and tested but want to know if the stator needs to be replaced and if so will it run without it as long as I keep the batt charged? thanks for any help

any body have experience with this that could lend some info?

well cleaned up cables and put battery in started right up ( battery was dead) but I do not think its charging as it nevr went above 12.8 ( where it started at) . does the above mentioned stator test condemn the stator? The rectifier checked out per the ohms test in manual.

Hi, The stator should be tested with no other connections to the circuit. There are only two wires from the stator. Neither wire should have a resistance reading to ground (any steel part of the engine). My stator has a resistance reading of 1.1 ohms between the two wires themselves. That should be about normal. I hope this helps.

Of course by now you realize the battery went dead because it isn't recharging.

I would question your rectifier test. Are you using an analog or digital multimeter? If digital, does it have a diode test function? Most digital meters without a diode test function won't test the rectifier.

Secondly, are you doing all eight tests on the rectifier? If it fails just one of the eight, it won't charge.

You speak of your shoddy cables. ANY bad or loose connections in the battery circuit will instantly blow the rectifier as soon as you start it up. Just so you know so you won't blow a new replacement.

I understand. Thank you for the etiquette lesson.
