Hooking up new motor... need help w/ connections and ignition circuit

Hey guys... Hooking up the power for the new outboard. The old motor looked nothing like this one so I was to make sure I hook up to the right spots.

I believe the power should connect to the right side of the solenoid (lower center of pic where nut is removed) and the (-) should connect to the upper right bole mounting the starter.

If that configuration is correct, I have verified the following

Power at Solenoid
Continuity between both large solenoid lugs
Continuity between switch terminal on side of solenoid
Continuity through neutral switch circuit


When I turn the key I get nothing. No click, clank, or other. The ignition system (boat side) worked with the motor I took off a few months ago, so I'm leaning more towards the new motor I'm putting on. I only see 1 fuse (20amp) on the motor. Are there any others I should be looking for? Breakers?

2000 40hp ELPTO 2cyl.

Thanks,

Rick

Re: Hooking up new motor... need help w/ connections and ignition circuit

I went through the test procedures on starter system outlined in the service manual. The test point to a bad solenoid....

The only thing that tossed my off a bit was the following test:

a. Disconnect BLACK ground wire(s) from Test Point 2.
b. Connect voltmeter between common engine ground and Test Point 2.
c. Turn ignition key to ?Start? position.

The problem with the test is the wire orientation in the picture below and what it actually was on the motor.

The pic shows BLACK on top and YELLOW/RED on the bottom... but it was the opposite on the outboard. SO to do the test I removed the black wire on the bottom terminal.

Does the switch care which side the wires are on?

I'm pretty sure the polatity matters. All a solenoid is is an electro magnet. One way it pulls the core, the other it pushes. It should click pretty good when charged.

Re: Hooking up new motor... need help w/ connections and ignition circuit

Your correct Mike. The black wire should be ground and the yel/red should be 12 vdc when the switch is in the start pos.Take a test light12vdc and hook the clamp to the yel/red wire and put the probe end in the main grd cable near where it bolts to the block and turn the switch. If the light goes on the switch and everything is good. Next move the light clamp to the black wire term.. and remove the black wire, an try it again, if it lights every thing is fine. if no light the selonid is bad. also check the black wire to the battry cable with meter, reading should be 1 ohm or less. on the 10 ohm scale. If everything is good so far put the light clamp to the starter cable and try the switch again, lights up starter is bad, no light selinod is bad. being you just put the motor on also make sure that the conections at the battiry are good. Test with light from pos. cable at selinod to grd. cable on block before doing any other test. Alot easier with light than meter when you cann't be in 2 places at once.

Hope this helps, Oldman570

Re: Hooking up new motor... need help w/ connections and ignition circuit

Thanks for the info and tips guys. I'm going to go back out and redo those tests.

The motor was given to me by my neighbor, who said all was in working order when they removed it from there boat to repower with 4-stroke.

I talked to a buddy that is a little more motor minded than me that said the tests I already did only confirmed that the solenoid was not working, not that is was broken/bad, and that he would think that the solenoid going bad just from sitting for a while seemed highly unlikely.

He said that I may have a ground issue and to redo the test I did with the negative switch terminal except but my meter on the detached wire and not the terminal itself to see if I have a good ground.

Again, thanks for taking the time to try and help out a fellow boater on a holiday weekend when I'm sure most of us are busy enough.

Re: Hooking up new motor... need help w/ connections and ignition circuit

Okay... I pulled the ground cable off the switch terminal on the side of solenoid and checked continuity to ground and had nothing. Looks like that is the problem??

The small ground wire disappears into a tucked away wire loom and I can seem to find continuity between it and any of the exposed (obvious) grounds.

Anybody have any idea where it attaches (or where it is supposed to attach)?

Thanks,

Rick

Re: Hooking up new motor... need help w/ connections and ignition circuit

Found it! I opened part of the wire loom and traced the ground terminal wire on the solenoid to small wire bundle that had been pushed up underneath the oil tank. It was bundles with 2 baby blue wires and the 2 blacks (grounds) where not connected. If face they both had female connectors on them so by making a simple jumper completed the circuit.

My new question is this... Why the 2 female connectors? They appear to be factory.

Any ideas guys?

dNot sure as I do not have a wireing schmatic for that motor, but I belive that the blk. grd goes to the ign. sw. along with the blue also. Black supllys grd to the sw. and the blue is for the choke. Best I can do for now, Sorry. I'll see if I can find out more when I get back to the shop.

The schematic I have shows light blue/ Black w/ white stripe as the Oil Level Switch. I thought that was for the warning alarm... is that actually the choke? Looking at this drawing, I don't see anything labeled choke. Hmm...

BTW,

Merry Christmas everybody!

Re: Hooking up new motor... need help w/ connections and ignition circuit

Rick glad you have the wiring diagram. Your right about the oil level switch going to the warning alarm. The Choke is the Fuel enrichment selinoid that also goes to the ignication sw. The two blue wires, and the blacks, have to go as the digram shows.
You should have it beat now, and a Very Merry Christmas To All
