Oh god let's not go over this again... Detailed quote from mechman told me 170amp is biggest I can go after that there's to much belt slippage so they sold it to me on the phone they told me 249$ ad it'll be shipped march 11th you'll see it in 7 days from that date... March 11th my credit card wa charged for 388$ march 25th I honed to ask about it to which I received horrible customer service and was refused when I asked to speak with a manager.. A few days later he swore at me on the phone hung up and ignored the phone after that.. Finally only after contacting the Knoxville tennessee police department and hosting an expensive 3 way conference call was I able to receive a straight answer on my alternator and speak with the manager... They did not send ye alt out until march 26th. He then apologized for that and for the person I was talkin to before who just so happens to have been the manager of customer service for 10 years. And he didn't know how to read a USPS invoice ? And swore at me because of it?? Really?? So yea then to top it off it got lost in the mail... I just finally recieved it on Thursday I think it was.... So yes we are now leaving my alt alone. Big three. And whatever we can cap the system off with that setup cuz I'm sick of this bull
