low beam always on

**quimosave** · January 21st, 2010 02:26 PM

nagupgrade kasi ako mga bossing headlight relay kaso ang nangyari eh laging nakaon yung low beam kahit naka high beam na ko, H4 headlight ko. toyota tamaraw fx oto ko, ive read somewhere na dapat 3 relays ang gagamitin kapag toyota kasi separate ang control nung sa low kaso wala ko makitang diagram, gusto ko sana katulad parin nung dati na kapag naghigh ako eh patay lang yung low.
baka meron diyan makapagbigay ng diagram on how to upgrade yung headlight ng tamara fx H4. thanks

baka may mali dun sa pag tap ng trigger ng relay.

yung DIY ko dati sa FX ko 2 relay lang din gamit ko. 1 relay for low and another for high.

baka may diagram ka sir. i would realy apreciate it.
or kahit value ng sockets taos kung saan nakakabit. thanks bossing

paki check kung parehas ang wiring nung orig socket.

ganimatin ko ng tester and had someone turn on the lights and flick the high beam para sakto ang triggering

i just analyzed your diagram sir, ganyang ganyan nga ginawa ko kaya nagtaka ko kung bakit ganun ang nangyari. i tried using other relays pero ganun pa rin.

tester mo din yung sa new sockets baka dun nagkaroon ng mix up

what do you mean sockets sir? yung socket ng relay or yung socket ng headlight na mismo, will do both na rin later.

just in case tama lahat yung connections pwede kaya ito,
found this on the net, since negative yung nilalabas nung stock headlight, pwede ko kaya gawin yan. bale ang nakakabit sa 85 is yung stock high beam (-) tapos yung 87 papunta don sa trigger (86) ng relay nung low beam so kapag naghigh ako eh magiging positive yung input sa low relay kaya hindi na ito iilaw. yun nga lang ang naisip ko with this diagram eh baka naman hindi umilaw yung low kasi hindi energized yung relay kapag nakalow lang yung headlight switch.

still a newbie when it comes to DIYing relays and it electronic in particular, i really apreciate your help.

kasi usually pag nag uprage ka ng relays, pati wiring upgrade ka. so may bago kang headlight sockets. baka dun nagka palit yung mga wires kaya steady ang low beam mo.

sir the relay in your diagram is different from the relay we use. it has one 87 terminal and one 87A terminal... when the trigger 85 is "off" yung 87A is "on" and 87 is "off"

kung regular bosch relay from local auto supplies, with two 87 terminals. which are both off when 85 is off. the diagram above will work too.

to make things easier for you. meron sa banawe ready made wiring upgrade kit for H4 headlights. hanapain mo yung brand ng NARVA, eto yung makapal yung wires. yung sub-zero sobrang nipis ng wires

aok.. will double check again the ceramic sockets.

yun ang catch, im from sta rosa laguna, medyo enjoy kasi ako mag DIY (Destroy It Yourself). hehe
if all else fail eh hanap na nga lang ng Narva Relay Kit for Toyota. thanks idol

problem solved!
stumbled upon sa net a a 2 relay diagram for negatively switched headlights. i used 2 30amp bosch relay, gauge 12 and gaug14 wires, 2 1N5404 diodes and 1 10 ohms 5 watt resistor. everything's working normal now including the high beam indicator in the dash board, syempre all DIY.
thanks guys
