- I think the problem has hot to be my B+ terminal. Going to clean it really well and re fasten. Probably didn't clean and get tight enough when I did the engine swap. Must've worked lose and got a little rusty and dirty over about a year
this you never mentions? engine swap? so many possibilities now that could have not been properly reinstalled.

It was just an engine swap. Early spring 2011, I think. This problem has been going on since April. So I went nearly a year problem free. The wiring harness is simple, couldn't possibly be anything there. It basically unhook and can be hung over the driver side fender, completely out of the way. The B+ cable was the only major lead I disconnected. What I'm thinking now is cleaning all of my pos+ connections and making sure everything is tight. I know, I know, this should have been step one but what threw me was that I was getting proper voltage everywhere. I think that just like terminals at a battery that are a little loose, will read proper voltage until put under a load.

Now that we know work was done in the engine bay, focus more in that area. Yes, loose connected can have proper voltage until under load. Definitely clean and tighten all connections. And make sure it's on the right connector.

Ok, took B+ terminal off and this is what was revealed. Cleaned very well, nice and shiny. You can see where this had been arcing and melted the plastic housing a little. Had to pack up for class, but I tried to turn the engine over with same outcome. I'll get back on tonight after class hopefully with a better update

I'm not thinking driving a fork lift truck qualifies you in electronic theory?

material handling equipment tech.
that machine is about 24000 pounds, and things get very interesting when you have to put it on jackstands and work underneath it.
also every wire is black, which is fun.

I didn't get that point either? I'm counter balanced forklift certified too, and it really doesn't qualify me as an electrician. Even if your forklift is battery operated.

I have a background in construction electrical, computer science and a few other electrical related skills. Automotive electronics is still a different system even if its only run my a mere 12v battery, lol.

Was goofing with you.
Bet you get some good stories from working with that equipment.

Used to work on Amtrak's Metroliner, so my daddy's bigger than your daddy!
Each car was about 80,000 lbs. and we'd have six strung together on test runs. Real rush to get going 165mph down the track. Ah, the good old days!
Pick'em up with cranes to work on them, but not my job description.

Don't sell us too short!
What's the voltage generated at the plugs, and what about those HID headlights?
And the electronics in an e46 are pretty sophisticated.

do i need to make a "who am i" thread, i never did that? lifting with a crane is always the best, you're never quite sure its going to work out until its over. i do alot of work for amtrak in chicago, but not on the actual trains. i did work on their ford f450 "dumper pumper" though.

Alright, the culprit was the connections at the B+ terminal. I cleaned all of my grounds and everywhere there was a connection from my positive. Cranks strong and tested all keys, all but one worked. Can't believe months of dancing around a problem and it was right in front, on top of the engine compartment no less. Goes to show, always start from the source I guess. Stinger, I appreciate the help, been there from the beginning. It's a big help when you have people asking you and pointing you in the right direction... Well knowledgeable people. Thanks again and take care
