1990 johnson vro horn problem

[powerwagon360]

just got this 24' toon boat with a 1990 90 hp vro johnson.Did not know that it had a horn on it till i started reading about it on here. so i pulled the hand control cover of to find that the tan, and two purple wires were sniped. Figers out that the violet with whit stripe went on the ignition switch and that the tan to the horn and solid violet to the + horn. pluged it all up and terned the key wating to hear the horn sound the short start up blast but it did not

so... i went to the back of the block grounded out the temp...still nothing so then i figerd that the violet was not geting power to the horn. I then ran a jumper from the + on the ignition swich. This made it work and it gave out a pulsing siren figerd out that its not the temp sencers.Its not the fuel preshure sender.I disco the oil tank wire so its not that.This testing was performed with the key on engine off. what could it be?

EDIT: this has a bran new 4 wire vro pump than the prev owner told us the marina put in

The purple wire should get power from the ignition switch when in on position

Re: 1990 johnson vro horn problem

the solid violet wire comes out the harnes from the out board is that the right wire to conect to the positive on the horn?

i just bought a new horn and ignition switch from the dealer got it all put back to gether. But it wont cherp when you ternt the key on it churpes if i run a jumper from the + on the ignition switch.

so why dont the perple from the outboard harnes have power?

Re: 1990 johnson vro horn problem

The purple wire should be connected to switch termial A , and all purple wires should be hot with key on. Some had jumper from switch to horn.

The following is some good electrical info and a key switch wiring diagram including the warning horn.

thank you that helps out some. i figerd out to run a jumper from pin A to the horn and THE TACK to the pin A . And i ran the violet with white stripe to pin C but i still have a solid violet wire coming out the engine harnes and i dont know were to splice it? i tryed tying it in to the A pin. but dont know if thats wright?

is this the accessery? shown on the wire diagram that seahorse5 gave me ? This is the only wire that i have left to wire up!

the last owner cut all the violet wires trying to shut the hot horn up! so now i have to fix his ****
