transceiver radio pumipito when accelerating

i went to see the technician who installed my radio and asked if ok bang magkabit ng capacitor sa radio, ang sabi nya baka daw tumaas yung voltage na papasok sa radio. is this true? but before i went to the technician, bumili muna ako ng capacitor, 16V 1000mFd, P7.00 lang pala ito?

Nope, not true.

capacitor is 16 volts, 1000 mFd - meaning rating is 16 volts. if the input is higher than 16 volts, iinit yun capacitor so baka pumutok. pag 16 volts or less ang input, ok lang.

alternator voltage maximum = 15.6 volts. yan ang papasok sa capacitor. pag labas nyan, 15.6 volts pa din. kahit na 20 volts pa ang rating ng capacitor, 15.6 pa rin ang lalabas.

ang sinasabi nyang tataas ang voltage eh pag ac to dc conversion. e rectified na yung voltage pag labas sa alternator eh, constant dc na yun hindi na sinusoidal yung wave form ng voltage.

tama ba na yung longer terminal ng capacitor ang positive side? try ko i-DIY tomorrow, ok lang ba i-tap ko lang dun sa me part ng fuses para hindi muna ako mag splice?

boybi...separate the speaker and the power wires...

second...

check THE GROUNDING WIRE AND THE GROUNDING POINT!!!

dapat walang paint talagang tinatamaan ang terminal niyang ground sa body..liha ng maigi yaN.

GlennSter, VHF Transceiver radio yung nagkaka-static sound. and the power is connected directly to the battery terminals.

i'm not an engineer but i don't think 16V or 20V capacitor si safe to use inside the car... try at least 50V or 100V .. most capacitors inside the car radios are at least 50V .. meron kasi surge ata ng voltage/current minsan..

sa mga may alam..paki-correct na lang po ako

sir, sabi ko nga the higher the voltage rating mas maganda. anyway, mag-leak lang naman or worst, puputok yung capacitor if ever di kaya ang voltage surge.

pero cars today na don't have those old style voltage regulators that cause those voltage surges anymore. electronic na so pag nag-fail yun regulator, 0 voltage output lang labas ng alternator. so kahit 16V lang kaya na. di gaya nung mga luma na voltage regulators na may contact point pag nag-fail yun may chance na pundido mga headlights mo kasi abot ng 50V ang output ng alternator.

so assuming na electronic na ang voltage regulator ni boybi (yun IC type) e safe yung capacitor kahit 16V lang yun binili nya.
