alternator smoking
The other day I connected a battery on my truck, and got a chance for the first time to see if everything worked. It does. My lights, a/c blower, wipers, radio, etc., all work. I coudn't get it turned over however. Then I smelled something burning, went to the front of the truck, and saw smoke coming from the alternator. It is one I pulled from the junkyard. Could a short in the alternator (which I believe to be causing the smoke) cause the motor to not turn over? The starter turned, and the engine cranked, just didn't turn over. Or could it be because the transmission, which is already blown, was in D? Thanks.

If you had a problem in the alternator, it could have possibly pulled the voltage down enough that it would not fire the ignition to the engine good enough to start. Was it cranking a little bit slow?

It seemed to be turning over a little slower than 'normal'. However, the battery is out of my 90' Mustang 4 cylinder, so that may also explain it. If the battery did have enough voltage, and the alternator was bad, like the one I have, could that also prevent the motor from turning over? Thanks Franklin2 for your reply.

While the key is in the start position the firing of the coil is controlled by the TFI Module and not the EEC. It uses Base Timing, if you advanced it to get more power it will crank slower.
If the voltage is low the coil will not fire as hot and may not jump the gap in the plugs.
