Overcurrent but Correct Voltage

[miked]

Hi Miked,

That ampere gauge in your van is not compatible anymore to your 110 amp alternator. Since it can only read up to 60 amp when you start your engine or rev up with no load it will hit the +60amp reading very easy. Worst case it will burn the ampere gauge because it cannot handle the load. So it would be best if your remove the ampere gauge.

It would be best if you use a voltage meter gauge instead. Yup your voltage reading is on the safe side. Over voltage would be 15 ~ 16 volts

The question would be: why would the alternator give more than 60 amperes when the stock A/C system is on? afaik, the A/C system would require lesser than 20A (if im correct).

kulang pa siguro ako sa informal tests. I'll try swapping a new battery then i'll see.

bale 3 ang nakikita ko sa bolang kristal ko:
1. defective current regulator
2. battery nearing its end
3. a defective component or load (like the A/C). could be partially burnt windings on the blower motor, etc.
