Overcurrent but Correct Voltage

Hmmm, much better kung may clamp meter ka with DC functions. If you want one, call 5th Avenue or Avesco and get their Kyoritsu clamp meters. Mahal nga lang ang isa pero compared naman sa Fluke, mas mura nang di hamak pero maganda at quality naman.

Another question pala, yun bang alternator eh IC type o yun kelangan pa ng separate regulator?

At starting kasi, normal yun mag-shoot siya to 60A dahil kelangan niya i-charge ang battery.

Kung suspect mo ang aircon, baka laging naka-on ang compressor at hindi na nag-aautomatic. Maybe nakasagad ang thermostat settings kaya ganyan. If ok naman ang settings, have it checked na rin.

Hindi kaya ng powers ko yung kyoritsu. nakita ko na typical prices nun. kaya yung fluke at klein di na ako nagbother na alamin pa. hehe...pero sigurado ako meron maganda sa may binondo area. hanapin lang ng maige.

back to the topic:

integral IC type yung alternator

nagcycle on and off naman yung compressor. minimum settings na rin yung thermostat. pero still have to check that blower bushing or bearing. baka dinadrag yung ikot ng blower motor.

why would the alternator give more than 60 amperes when the stock A/C system is on?

that's not what it says on your 1st post

With the A/C on (front and/or rear), ampere gage registers beyond 30 A (approx. 40A)

sorry kinulang pa pala sa kuwento...same attitude din kapag i-turn on ang A/C. magshshoot beyond 60 A then go down littlle by little to approx 40 A.

Normal lang iyon high current na iyon.

Actually , aircon compressor have no electrical connection. Pulley driven ito. Ang nakikita ko lang pwede mag create ng high surge current ay mga dc motor. Gaya ng Condenser Fan and Blower Fan and which will turn on if aircon was activated . DC motors tends to draw high current due to its inductance and commutator inertia. But once the commutator have already gain its speed. The high current will drop to its normal dc motor drawn current. Sometimes we call it startup current.

brader, the magnetic clutch requires current to engage the compressor. AC motors also behave similarly with respect to starting current. cheers!
