Thanking you in advance for any answers provided.
The problem: Car starts fine and runs fine without any excess load on car and while car is warming up AMP meter reads 14+. Once load placed on car (ie. A/C on or lights on or both) and car is at operating temp AMPS drop off to 10-11 AMPS and car misfires. (car is MSD ignition equipped) Once external load turned off (AC or lights or both) AMPS return and car eventually returns to normal operation.
Attempts to fix: Have had alternator rebuilt by local shop who believed that once ALTERNATOR warmed internal voltage regulator and diodes failed to perform as normal so they replaced both. Basically they rebuilt entire regulator. BATTERY has been checked and indicated it was putting out 540+ Cold Cranking Amps which is what the battery is rated. Battery is at least 3 years old.
Your thoughts ladies and gentlemen.
