Ok, so I checked it tonight.
When idling without the lights on, it was registering at 16.9 volts. When I revved the machine it went up over 17.5 volts.
When the machine was idling with the lights on, it was registering about 14.0, but when I revved the machine it went over 15.5 volts.
So, now that we have proven your hunch, what do I need to replace now? Sounds like the voltage regulator which is right behind the ECM?
Here's my conundrum, if you are right on this, will the machine really work fine? Possibly right? Funny that the machine was throwing the 12blinks code, which seems to be completely erroneous at this point.
If this works, I certainly have NO PROBLEM paying you for your help.
Fingers are crossed, let me know what you think.
