engine and drivetrain Still having electrical problems

[chuncomunco]

I've changed the alternator, voltage regulator, and the plug that goes behind the alternator since the last post i've made. I'm really bummed out and so is my mechanic. Something tells me that the engine wiring harness needs replacement!

i might have missed the original post, but what is the problem?

The red "L" light stays lit solid all the time and I can definitely feel the engine kind of cut out when the battery is low.

[steve k.]

so do you think the battery is not charging?

Can you check the voltage at the alternator and the battery when the car is running. You should have at least 13.7v at the alternator. There should be very little loss at the battery. Still staying at 13.7. Then measure the voltage between the positive on the battery and engine block, then positive on alternator and engine block. Those numbers should give a lot of information.

The voltage at idle is only 12.7

at the alternator? does it go up at higher RPM?

A while ago, a question to you was never answered:

You gave us the long version of the mysterious crude leak. Has it finally been eradicated? What was the ultimate diagnosis?

Maybe you never saw the post. Maybe you were too busy working on new issues.

In any event, it should be obvious that some of us less mechanically inclined, may find it helpful to learn from these shared experiences.

I was lucky, my mechanic did a "warranty repair" and its no longer leaking!
