Toyota Revo Low Headlight Power and Low Dashlight power

[dynamo1131]

Mga Electrical gurus, I have a problem on my headlights, mahina ilaw nya, at ung dashlights ganon din, napalitan ko na mga bulbs ganon pa rin. Toyota Revo MT. Ano kaya culprit?

there is a voltage drop. bad grounding or wires are already resistive..

So to fix this I need to change the wire sa grounding?

start with voltage drops

Additional info, pati nga pala ung busina ko mahina......

kahit na uma-andar ang makina, mahina pa rin?

actually nag fluctuate sya, revving medyo umaangat pero barely, kaya pag gabi parang walang headlight....

check your electrical connections, po.
battery terminals.
alternator wires.
etc.

errr... hindi naman siguro, pang-ibang sasakyan ang mga bumbilya mo, 'no?

sige sir, ganon gagawin ko, pang toyota boss, same wattage as stock.

baka may maliit na wire sa tagiliran ng alternator mo. kung minsan kasi ay kumakalas o lumuluwag...

Baka mahina output ng alternator. If that goes on, mamamatay ang battery mo. Pa-check mo sa Auto Electrician.

You have to check which side of the circuit has the high resistance. The way you described it, the problem is more than likely the chassis ground since you have problems with the other loads as well.
Get a DMM (digital multimeter) . With a fused jumper, check the voltage between the battery terminal positive and the negative terminal of the headlight socket. Do this too between the battery negative and the positive terminal of the headlight socket. The voltages should not be less than 0.5vdc less than the battery voltage. If one side displays a low voltage, that side has the high resistance.

bro, nangyari din sakin ito mga ilang buwan na, assuming all stock pa electrical system mo, ipa check mo yung external voltage regulator or alternator.

oo nga eh, ok lang sa umaga eh, pero sa gabi parang walang ilaw, hirap mag drive, hindi nakatulong manyak tints...lol

How many years your motor has?

ano pong motor ung sinasabi nyo?

[dynamo1131]

update lang regarding dito.....I ended up buying new battery, kasi isang araw it went dead...pero when I got a new battery still the same guages and light. Mahina sya talaga....ok lang ba na taasan ko ng wattage ung mga peanut bulbs sa dashboard? Headlight sinasabi ng electrician is palitan ko na daw ung assembly kasi foggy na ung plastic...kaya malabo na.
