motor model V4AL15E
SUPERSEAHORSE
Electric shift
motor was advertised for parts so i bought it $25 bucks seemed fair
motor must have been removed from boat by cutting wires..
is complete and has good compression....

let me take a minute and explain the wiring to you,and hopefully one or two of you can instruct me how to power up the coil to see if this thing will spark and shift.

there are nine wires besides the main pos. and neg. that are for starter.

there are two large white wires (one with a blue stripe) also a red wire and blue wire that head up under flywheel(the red wire splits and the split heads to coil)
other group of wires have a brown wire which i think is a temp. sensor,and a white wire that goes to a microswitch on distributor.and a grey wire that connects to other coil terminal.
and the green and blue that head downtown for the electric shift.
Phew!!!
now i know this needs a junction box with solenoid and what not but is there any way to check for spark without the origonal wiring and junction box?
i have a parts catalog and wiring diagram on the way,but thought i would see if anyone has had any luck hotwiring(so to speak)
thanks in advance for any replies

Pretty sure you need to have it wired and a battery connected to test it. Sorry, it's not the same as the magneto version that will run without a battery.

Re: 1963 johnson 75 hp wiring question

my parts catalog arrived today,and is no help..it has a break down of junction box,but does not identify wiring.

can anyone supply a wiring schmatic for this motor,or usable advise ,or pictures...

what do you think would happen if i gave the coil 12 volts???

are these motors so difficult to understand,i have searched the forum and find nothing...

how about testing the elec. shift power one wire at a time for forward and reverse?? and when hooked up to positive 12 volts where do i ground ??

well i went ahead and hooked up a jumper wire from battery to wire that leads to coil,turned off the overhead light to see if i could see a little spark(did not need to turn lights off,could hear the spark) the nicest blue snappin spark you could ask for,so now i will rig up a solenoid and will be good to go.

hope this helps anyone else with similar situation.

sorry i did not hear from all the admirals ,commanders and what not.but if you still wanna pipe in let me know how wires from stator hook up,or wait a few days and i will figure that out,good day .......

I'm not an admiral but can help you out with a wiring diagram. Send me a PM with your email address and I'll send you a scanned copy. Good luck!

Done, 1960Glaspar! FYI, the forum moderators prefer you do not post personal email addresses in threads. They should be sent in Private Messages.
