Okay so i was driving to get my cam spring installed the other day, and all of the sudden weird things started happening in my car. First thing i saw was my ABS light started flickering on and off, and i thought nothing of it. So i was like humm okay... Then my raido cut out i was like hummm interesting.. then my gauges died and i was like okay this aint good. lol. so i turned off everything on my car (fans, Ac and radio) only i put the radio to voltage metter so i could see how many volts my car was seeing. And it was showing 9v's i was like crap ... my alternator??? well i slowed down and it went back to 13.6vs *with in spec for charging* and then i took it into a shop and now were diagnosing it, and so far it says update the ECM with the newest flash... So i was thinking has my ECU gone bad?

Im running a hondata k-pro. But im also thinking it could still be my alternator. My voltage has been varing since that day, so im thinking along the lines of my voltage regulator. Any thoughts or suggestions?

well the voltage regulator is built into the alternator on most modern cars now a days, its either a faulty alternator or a wiring problem somewhere...the gauges dying and lights flickering says to me that its an alternator, how many miles on the car?

well a wire could have rubbed against something and wore thru and maybe just touching something back and forth touching then not touching its worth looking

maybe a cop shot your car with one of those tri-point things from 2F2F and the third one was only kinda grounding, j/k

alternator related 95% guess, 5% says your positive terminal connection is loose and is getting a poor connection

nope not the positive terminal.. i went threw 2 battery's today getting home. and when i start the car and pull the pos or neg the car dies.. so i have no charging system at the moment. Which means A) my alternator is dead, B) like blue j said loose wire.. im going to investigate on thursday or sunday when i have some time!

I know autozone's check alternators for free if you can either get the car there or the alternator there

Can anyone show me what an ELD *electronic load detector* is?
It's a clamp-on style current meter that measures overall electrical load--that is, current that flows through the ignition switch. The ECU/PCM monitors both voltage and current to regulate alternator output. The ELD is in the under-hood fuse box.
