Hi Guys,
have seen a couple of mentions about the crappy ability of hilux alternator (petrol v6)
I am having a rather annoying issue currently where, if i have my spotties, highbeams , foggies, and DC-DC charger on (and the usual load of the car itself) ... my alternator is unable to keep up, and I start depleting my primary battery.
In the day time the issue is not there, the alternator can keep up .. infact even around city with low beams it's OK
But on a night drive (sitting at 2000rpm), she simply can't keep up. My DC-DC (redarc) actually removes itself from the equation when it detects low voltage (ie when the battery is nearly bloody flat) ... but even then the car has a hard time breaking even with the primary battery charge level, if i have all the candles lit on the bow.
Anyone had experiences with getting these factory alternators to boost some output?
One of my best mates is an auto sparky and even he's scratching his head (we're now toying wiht idea of having the alternator rebuilt and beefed up by him ... or purchasing an aftermarket 130amp alternator).
Surely though these hilux alternators can handle a bit of load ... a pair of spotties (lightforce blitz 240), and a DC-DC charger (draws probably 25amp, to deliver 20amp to aux batt) is not THAT big an ask?
