Bosch Europa Horn Installation

[augustus]

Has anybody tried to install Bosch Europa's?
I just got mine and noticed that the connectors do not indicate polarity for positive and negative.
Are they interchangeable?

may polarity po yan. btw hindi lang tutunog pag nagkabaligtad - no need to worry.

Thanks will check it out!

hmmm... yung europa ko parang may + - ah?

anyway tama di nga tutunog yan pag baliktad just make sure meron kang inline fuse at relay

ala polarity yan. use large gauge wire pra maganda tunog masmaganda kung tig-isa na relay habang naluluma kc yan naghahanap ng mataas na current eh
kaya ung iba nasisintunado na at pagrainy season alagaan mo ng WD-40

Slightly OT, do you know the frequency of those horns? The one we bought na standard Bosch "pit-pit" have 420Hz and 335Hz for the high and low tones respectively. TIA ;)

Thanks everyone for your inputs.
I started my installation yesterday and did a few tests and here is what I found.
1) The horn's metal parts cannot be grounded.
2) The terminals must be connected to + and - connections and are interchangeable.

mbeige, in answer to your question, the horns frequencies are 300Mhz and 375 Mhz. I have heard of some people fine tuning and adjusting the horns to a higher frequency but haven't yet discovered on how it's done.

yan ba yung aluminum face? madalas gamit sa old benz? kasi kung yun nga, madali ng sya masira pag nababasa.

don't tinker with the frequency magloloko yan. but if you really want to tinker with it, its that black glue-like thing near the word bosch. you'll have to remove it the you will see a screw inside which you can turn to adjust the tone.

and like Joey said put a relay, it needs a strong stable current.
