So the good news is that after replacing the battery almost all of the electrical seems to be working. The not so good news is that one of the things that isn't working is one that I need to pass a safety inspection to register this thing, a horn.

Please see the attached pictures. Right beside the horn is a square black electrical box with only one plug with a lot of wires.  The box is named Eagle Rock; On the side it has #019665.  This box is located near the horn as can be seen it the picture.  All of the connections to the box and the horn look good except for one black wire coming from the square black box which has been cut.  This wire can be seen standing up in the picture of the black box.

Any idea what the wire is, if it is anything important or how to get the horn working?

Switching to the radio.  It may be simply that I don't know how to operate it correctly. I have checked the inline fuse for the radio.  The fuse was good and the radio is getting 12 v.

Thanks.

the box with all the wires is an alarm.
are you getting power at the horn? 2 wires to the horn?

Is the cut black wire an issue for the alarm?

No power at the horn John.

If the black box is an alarm, what are the chances that the long wire that is attached to it is an antennae for a remote like the radio has for FM? It would sure be great if it wasn't related to the horn and wasn't any kind of an issue to worry about.

black wire is an antenna.

check for power at the horn switch.

So glad to hear that the black wire is antenna and is nothing to worry about.

Now I still have the horn & radio.

John that was my next plan of action. I am headed to bed for tonight.

[bob123456789]

No power at the switch. It sure seems like a blown fuse that I can't find. The only two fuses I could find are the main one by the battery and an inline one on the radio power wire.

Are there any others?

[tvnacman]

Yes with 4 fuses, here is a diagran, I cant link you my computers cooked.

Its in the tech section on professor. If I can post the link I will.

First off the problem is NOT the 20A fuse if that was blown the ENTIRE SCOOTER would be dead. But the 20A fuse is on the SOLENOID if you want to know where it is.

OK the horn itself is bad. The wiring goes through the alarm. I suspect the alarm is no good. Anyone with a good wiring diagram so we can work past the alarm.

The horn only has TWO wires the ground and live wire. I would first check if the ground wire and then if voltage is getting to the horn when the button is pressed.

The horn is connected to the alarm using two wires. These are dead even when you push the horn button.

I also connected the horn directly to the battery and the horn did not make any sound. I connected a replacement horn directly to the battery and it works fine.
