Hello everyone,

I purchased a 6g alternator from a reputable source on eBay, having issues.
The seller is well known to the mustang community, he offered his advice and help, even sent another regulator at no charge. I swear it's an alternator issue, please read on....
My OEM alternator worked fine until about 10 years ago, I replaced the regulator with an autozone regulator and had no issues until recently, she just quit charging. Diagnosis, no output, regulator likely failed again.
I bought the 6g cobra mustang 160 amp, bolts right in, only minor change is the plug. Immediately after installing, I noticed the voltage was awful jumpy. Charges just fine when the system is stabilized, but if you add a load such as cooling fan, it sends the voltage into a series of surges. At times, it peaks near 17 volts and the the computer cuts off ignition. During cruise is more stable, but when it does surge and ignition cuts off, it jerks the car pretty bad. Similar symptoms to a cutting out DIS, which I have experienced in previous years.
Has anybody seen this with the newer 6g? I've spent countless hours googling all of the possible tech help and regulators, have now tried 3 different styles with no luck, all respond the same.
Seller recommended fresh battery as well as new cables and grounds, battery terminals, numerous engine grounds, ecm ground,which ofcourse I have done, to no avail. The key I have noticed, it doesn't spike when the load is applied, it spikes when the load diminishes, AKA "load dump".
Anybody willing to try this alternator in their car? I'll pay shipping. I'm at my wits end wondering if I'm doing something wrong or if the issue is actually something else with my 90 auto.
Idle voltage in gear is the normal 14.2-14.4 ish when stabilized, I believe she's spinning plenty fast at idle even with the larger pulley than the sc. The engine drops rpm just like normal when the load kicks in, so the alternator is responding to the loads, just seems to overcompensate when the load dissipates.
Ofcourse when I disable the alternator and run off the battery, all of the cutting out symptoms disappear.
