Charging voltage is related to ambient / battery temperature and how much load you get from electronics.

14,3V is not bad.
Check your battery voltage in rest and say power on & lights on.
If you get somewhere between 12,5 - 12,7V at rest and above 12V with lights on, its definitely not the battery.

Looking into your previous post you have kind of tried almost about everything. High HC anyways should mean that some fuel does not get burnt and goes to exhaust (and that will eventually kill your new CAT).
You had already your valves adjusted and only other possibilities there would be weak spring or not sealing correctly, but as your spark seems low I would continue investigating that and leave the valves to the time you have checked everything imaginable on electronics.
You did not mention how much your car mileage is. Mine has 250 000km which is approx 155 000 miles. Mine is running with original valves, just some adjustments and replaced cylinder head cover at 242k (it had hole burnt there for one cylinder.. no idea what happened when it was with previous owner).

I have been told Geo Tracker / Vitara has quite shit groundings. So I would search the site for electrical wiring diagrams and check & clean all groundings. I have been especially told to always disconnect battery before any welding as the shit groundings will cause problems, even blow the ecu.
Mine had several shit groundings for lights, trailer connector and fuel pump (corrosion). There is still one for wipers, or their wires them selves are shit. Also some of the wire connectors on my car are bust. I had to replace connector for rear fog light and fuel gauge at rear end of the car.
If my wipers are on mist I cant start I just hear the solenoid and/or starter doing sound like drill with hammer function on. Mist setting works just fine after car is started up. Haven't yet had time to figure out where/what that is.. I just found a fist sized new hole and I cant pass inspection until I cut some rusty steel away and weld new one, so again the mist settings is last on my list. :/
So in addition to bad grounds you could have bad connectors. Pain to find as nobody probably knows what the resistance should be between front and rear for some wiring set. So easiest to start with grounds I suppose.
= Bit non related FYI crap.
I have cheated our smoke test by blending E85 with 95E10 before going to the test, but I would NEVER do that when the spark looks bad, as you need more fuel that has less energy its probably no-go with weak spark. Probably just floods engine and eventually CAT.
Also I have no idea how much this car can take it. I know Saab 900 non turbo can go with 50:50 mix, but its different for different cars/engines, and how much ECU allows or injectors can give more fuel until ECU goes out of normal tuning range and thinks its a fault -> Check engine light ON. Or if you have too much E85 there is no idle at all, need to press pedal to run.. or won't even start.
Idea here in that is to burn less gasoline and more ethanol which is cleaner -> gets lower values for pollution. In your situation there probably is no mix which would allow the car to run and pass the test. :/
I guess I will shut up after this post or fixkick will kick me out from the forum
