This is a puzzle and I'm looking for help.
It has rained alot here in the last month and son drove through a big puddle and he says all the dash lights went on.
Within a week the battery was dead and everything pointed to the alternator.
I replaced the alternator and everything worked fine for a week.
Then dash lights came on again and engine died. Dead battery...
Troubleshooting said bad alternator.... everything ran fine with 13.8+ volts at the battery. 2 hours later the lights are back and the battery with engine running is 11.7 volts...
Seem alternator is not working again.
I have done some research and it seems the regulator might not be "waking up" via a signal from the "dash light" .... not sure what this is as the internet, as usual, is not well versed on this issue.
It seems when the start sequence is initiated voltage is sent to the alternator to wake it up and tell the regulator to start charging.
My question is what voltage should I have on which of the two wires going to the alternator plug (two wires).
I can't find a good schematic of the full charging system to see where those wires go and what the voltage should be. HELP EC!!!
