That model has been discontinued since 1994. The closest replacement we offer is our part number 10029XLP. The only difference is the mounting pattern. We no longer offer a horn with the same style of mounting as the SPTD.
We suggest bench-testing the horn and wiring it directly to a 12 volt battery. If it works fine when doing this, then the problem is most likely within the application’s wiring. If the horn still only puts out a clicking sound, that is usually a symptom of one side trying to draw more amps than the other which causes them to cancel each other out. Remove the rear cover and find the screw in the center of the sounding mechanism with a small red dot on or next to it. Turn that screw a little bit counter clockwise and eventually the horn should start to sound properly. If not, keep trying each side, back and forth, counter-clockwise or clockwise. If still no positive reaction after all that, it’s time to replace the horn.
It might need some oiling.
- Reverse the wires so the compressor “pulls in” rather than “blows out”.
- Insert a few drops of light machine oil/ sewing machine oil into the opening for the hose attachment.
- Let the oil swirl around for about 4 – 6 seconds.
- Then reverse the wires back to the correct position and allow any excess oil to exit. (Do not allow oil to get into horn)
If this does not improve the functioning of the compressor it may need replacing . The compressor should put out 9-11 psi.
No, this is not our product. That would be Signaltone items made by a company called Fiamm of America.
Yes. The part number for the 12 volt compressor is 10102. The 24 volt compressor is part number 10224.
