I have an 87 FJ60, 2F, and the Hi-Out SOR alternator (put on last year). The voltmeter has been reading lower than I think it should lately. In the past, it's always read just under the 14v mark and moved a little with blinkers or wipers, no biggie..and if everything was on at a stop light(heater, rear defrost, fog lights, high beams, etc...) it would dip down to just above 12. Never stalling or anything.
Last night, while driving with just the regular headlights, it read about 12-12.5 and at or just below 12 when stopped at a light...never stalled and idiot light did not come on. Seems low to me.
How can I tell if it's the battery or the Voltage regulator or something else?
If it's the battery, what's the feeling on Optima (and what color) vs. the good ol' Interstate Battery?
Thanks
