After I replaced the the alternator for a second time with a factory one the batter still would not charge. So I decided to take another look at the fuses under the steering col. I didn't check them all last time since most of them were like heated seat fuses. This time though found out that my ECU fuse was bad. I replaced it and my d4 light immediately stopped flashing and after testing my battery it was now receiving a charge from the alternator.

Here were all the symptoms caused from the ECU fuse shorting out.

1. D4 light blinking steadily on cluster.
2. Auto Trans having to be manually shifted on col.
3. Battery going dead not receiving charge from alternator.
4. Alternator appearing to be bad by not charging the battery.

So after having the transmission fluid flushed three times, purchasing a new battery, a new alternator, and having put in $750. It all came down to a fuse! Oh well, I guess the money was spent well on preventative maintenance and the bearings in the alternator were going bad. Should have gone with my initial instinct and check all the fuses instead of assuming the guy at the shop knew exactly what he was talking about.

 

damn! i feel for ya. that sucks learning things the hard way. been there done that one too many times.

 

Glad to hear that you figured it out. Sorry that it was at such high expense,

 

See trouble shooting does work and it's usually cheaper.
