Engine wireing

[marko69]

Hi all Ive been rewiring my 1980 Johnson 85 v4 engine
and I've got some probs , firstly I've wired the ignition
switch to the engine harness I think as to the manual
I got power on all cables and to the choke but engine
didn't start ? what am I doing wrong
secondly I've then sparked two wires together and now
there is no power to any of the wires at the ignition
switch ? Why . would I have done any damage or just
blown the fuse in the engine of which I can't find any ideas
would be great as I can see this engine fast becoming
a mooring anchor !!!!!
thanks mark

Re: Engine wireing

Well first, you probably blew the fuse. It is in a rubber fuseholder in the red wire somewhere near/ leading to/ the starter solenoid.

Have no idea why it won't start without knowing what you did wrong. Do you have a multimeter and know how to use it and how to read a wiring diagram? That is the next step, unless you just want to start throwing parts at it.

Hi thanks for your reply I've got a multi meter there
was 12.8 v across the board before I shorted the
ignition switch now 0 volts except through the tilt n
trim I guess I have blown the fuse as there is still
power from the batt to the engine at the multi plug
Thanks again mark

Re: Engine wireing

just a thought , i read somewhere that a automobile ignition switch will not work on a boat motor. sounds like you are doing great good luck!

Re: Engine wireing

mark take a look at this link it may help you work out the problem. If the engine cranked but you had no spark the black/yellow wire might have been grounded by the key or by the kill switch. If you have lost power to B at the ignition then you have blown the fuse that is connected to the battery side of the starter solenoid in a red rubber holder with a metal clamp on it as f_R said.

Re: Engine wireing

hi all thanks for the replys ive now found the fuse and it had blown ,my ignition swith is not the same as the one in the link but as it was
already there and it works its just a case of rewiring it up .one thing i have found is that the last owner had wired the
neutral start switch to another type of ignition switch now lm looking for some 4 new dials, rpm amps, temp, and a clock lve got old
teleflex rpm and amps and there looking old now so somthing new would finish the consol nice
thanks again for all you replys ...............mark
