Charging voltage

[1-2clutch-u]

Wondering what my charging voltage should be with all the loads on. Headlights, blower on high subs on dubstep mode. and E fans going. Mine drops down to 13.5 ish with engine at idle. With the engine at 2.5k or so it only gos up to 13.8ish. It might be time for the mr2 up grade? What year do I need, turbo or non turbo?

Those voltages look ok to me.

As long as it stays above 12v with loads,your fine its charging.

Well, 12.5V actually.

You include subs in that, and it's hard to say anymore, but that doesn't sound like a problem to me. 13.8V is the nominal regulated voltage, and is perfect to keep the battery charged.
