Horn slow to activate

Post by RS23V0G »



Has anyone had a problem with the horn slow to activate? My 87 Aspy takes 1-2 seconds to blow after hitting the button & obviously that dangerous.

Assuming power is reaching the horn as soon as you press the button (check across horn connections with a multimeter or test bulb) it probably just needs a little tweak of the tuning screw on the back of the horn.

I forgot to mention that one of the horns is OEM and one is an automotive aftermarket. But the problem started long before I added the aftermarket one. I'll check your suggestion first.

If both horns are affected, the tuning screw won't help.

my guess would be a corroded pathway. i would remove and clean all connections and switch contacts.

If you have two horns, and one is an automotive horn, I'm willing to bet the circuit is overloaded, and potentially has burned out the contacts on your horn switch. The wiring and switch for the horns is just barely adequate for the OEM horn system, and the full current for the horns is pulled through that wiring and switch.

If you put a high-amperage (like 30 or 40 amp) automotive relay in place of the horns, then run a new (fused) 12 or 14 gauge wire directly from the battery, through the relay contacts and from there to the horns, you'll get much higher current to the horns, the horns will be much louder as a result, and you won't burn out the horn button switch from overcurrent.

WingAdmin,
Great suggestion, I had considered adding a relay so it looks like i have another project. BTW, What brand relay do you you prefer?

Thanks!
Garry

I buy them in bulk quantities from Digikey, and I normally stick to brands I know. I looked it up, and the last time I ordered some, I bought 25 of these: https://www.digikey.com/product-detail/ ... -ND/646989

Thank you! I've got a vendor that can supply these and has a pigtail also.
