I have this car problem. Bigla na lang namamatay auto kapag full load. Naka-on aircon, ilaw, stereo. Nangyayari ito kapag nag-preno ako or shift lights from low to high beam. Iilaw muna battery warning light sa front panel then stop na makina. Parang di kaya additional load but when I re-start it, OK naman ulit.
Sa tingin ko hindi battery or alternator. And another thing, napansin ko sobrang init ng negative pole ng battery ko pero hindi naman masyado maiinit battery. Ano po kaya problem nito. May car is Honda 95 model. Thanks in advance and God bless.

It might be your grounding is bad, with the age of your car it is possible. Install a grounding kit or have a car electrician make one for you or you can even do it yourself. Just google or check out the thread here about grounding kits.

Since there is not enough power to go around between the engine and the rest of your electrical loads, the engine dies.

Solution is to check if the terminal is still in good condition. If yes, just clean the contact areas and fasten it securely.

Sir ghosthunter, few questions lang po...

1) Pano po ba normally nililinis ang terminals?
2) Liha lang ba ang gagamitin to clean the surface or pwede din ang old toothbrush, etc?
3) Then apply the vaseline sa palibot ng terminals?

Napansin ko lately na mainit ang negative terminal ng battery pati na un wire, baka kasi makuha sa linis ang problema.
Im also having almost the same issue, but good thing hinde naman umaabot sa scenario na namamatay ang makina...the only problem is bumababa ang rpm ng auto pag nakaopen ang headlights Is it contact point, condenser or battery ang problema??. TIA
