ok is the smoke black like to rich?
yes the regulator is build inside the ecm computer and to test it you need a voltmeter just connect it to the battery and see what the voltage is, it should have at least 13.0 volts the lowest, another way to check if the computer is the problem is with a scanner you need to see if the computer is switching voltage to battery and then to ignition.
OK. I was under the impression that the voltage regulator was contained in the alternator and that changing the alternator might make a difference.
Which is the ECM computer? The one behind the battery or the one on the firewall? I changed out the one on the fender, so unless the brand new one went bad, I don't see that as being an issue.
It wont idle so testing the charging system in situ won't work. I pulled the alternator and had it bench tested, and I was told that it worked fine. However, I've had items (alternators, in fact) that bench tested as OK but wouldn't work when they were in reak-time use. I'm thinking about getting a junkyard alternator to see what difference it makes. It won't cost much. Unless you have another idea.
How do I boost up the amount of money this is worth to you? You've certainly put a lot of effort into it, and I certainly appreciate it.
does it starts and stalls ? can you hold the gas pedal and try to keep the rpm at about 1200 rpms to prevent stall? and do the charging test then. i really dont think that the reason for stall is because the alternator is not charging , have you tryconecting a booster pack or jumper cables from another car to prevent it from stalling?
