DIY Hella Twin E.Horn with Relay

[Jfor_Jimmy1986]

hi.. currently i have a Hella Twin Electric Horn.. it was fixed on my s4..

 

but then whenever the horn is being blast when my bike in stationery, the sound is weak... (or not 'perfect') .. my voltmeter will show 9.5 - 10v if i blast the e.horn..

 

i was wondering can i get a relay and how i install it myself?? thanks...

[levin]

The one who fix for u didn't fix the relay for u? Relay is going to help by not burning the stock switch, its not going to make the horn louder or boost the voltage higher if u know what a relay is. When u say bike in stationery, means engine started or not?

[levin]

If u want to DIY.

 

From battery , go to a 20A fuse ,then go to pin 30

Pin 87 goes to your set of horn on the +ve terminal (the -ve terminal of the horn gnd to your chassis

Pin 85 gnd to chassis

Pin 86 goes to your horn switch

 

 

Hope this help

 

The diagram show 2 relay, just refer to the one on the left hand side and ignore the pin 87A

haha i fix it myself one.. i plucked out the stock horns and fix the hella w/o using any relay.. so i find it's quite dangerous because the batt comsumption very high... the pic u shown me look quite chin lehh... keke...

 

err... i think there's a guy in the forum selling relays rite... ?

 

what type of relay must i get ? which model...

 

thanks!

for horn that draw excessive power, usually relay will be provided. If somehow there's no relay, good luck finding a suitable one.

 

perhaps someone with electronics knowledge can advise you on an aftermarket one.

[Jfor_Jimmy1986]

i went to motorshow to buy one.. hella...

[anodise57]

From what u mention, u bought the Black New Gen Twin Tone right? This one don come with Relay, only the Red color one has.

Anyway u can follow this Wiring Diagram its the same.

If no relays were installed. The full potential of the horns will not be realised.

U cannot say its chim cos this is the way to connect up a relay. U can buy relay from motorshop or autobacs. Just tell them 12V relay. Car or motorbike usually use the same type. If u find the diagram a bit blur , refer to the one anodise57 posted.

[anodise57]

Just go to autobacs or Concorde Accessories ask for a Hella 12V relay for Horns. Should be less than $10. Connect up as shown.. Simple la....

If not u go to a bike shop ask them fix for u lor.

Yup one of the forumers selling bosh relays....w/o relay the horn will be weak ,with relay the current drawn is more consistent/stable thus giving u a better horn sound level.

does the relay consume electricity? or just the horn itself??

[h4hahak1m]

Anyone got the wiring diagram for the stebel nautilus? I got it 2nd hand, horn, relay and the mounting stuffs but i can't do wiring. Thanks

just google it. no kidding, there's dozens of diagrams. Heck, even the diagram meant for air horn works, if u understand the basic concept.

Relay does not consume at electricity,just the horns.

 

Relay acts as a "switch".to prevent over consupmtion of electricity which might damage the horns and switches.

The wiring all same which are using the relay.

 

Just need to know which wire goes to which terminal of the relay.

 

correct me if i am wrong

 

terminal 30 is batt +

87 is power out for the horn

86 is to switch

85 is to ground.

[Jfor_Jimmy1986]

ohh anyway thanks all for ur inputs..

 

i got it fixed.. but not by me..... lol.... paid 15RM ...

can explain where exact are the locations of those pins. Cos i dun hav the bike manual & would lk 2 learn hw 2 install it

[Jfor_Jimmy1986]

you have to bought a relay. the pins are attached to the relay....

[MC28]

And it would be good to add in a 15/20amp fuse inbetween the battery + to the relay..

[Jfor_Jimmy1986]

haaa.. basically is to change the fuse to a 15/20amp in the fuse box...

anyone knows what happens if water goes into hella horns ?

 

my hella horns sounds like pi-pi-pi... then i have taken them out and saw so some water droplets inside the horn.

(dont know heavy rain or stup!d bugger at bike wash)

but was not as loud nor sharp as before..

 

isit cure-able ? or have to buy new one ?? ah.. wasted for hella horns...

guys is it possible using 1.5mm wire for connection?

[shunoski]

I have a hella relay, it cames along with my Hella Twin Tone, but I didn't use it as there's another relay with my previous horn. If you can make the trip to Sengkang, I'll give it to you. No point charging few dollars for something I don't use.
