I have had to put 3 new Alternators on my 87 turbo Buick all within the last 1000 miles. I have a scanmaster and can monitor the output. All three new alternators worked fine when first installed and will show 12.5 to 13.5 volts. After driving the vehicle for a short time the volts drop to 10 to 11 and never get better so I just replaced the unit. I have a theory based on the fact that the igniter wire is only getting 8 to 9 volts and should be getting 12. If anyone can help I would greatly appreciate it. thanks ben
