Well I posted about a
dead heater blower and got little response/help but I believe I may need an alternator.

I see many for sale on the web some Bosch, some Denso and some
USA INDUSTRIES .
Some are 70 amp some are greater. I am hesitant of purchasing a 70 Amp. I understand many believe I need to buy an OEM ALT but those cost big bucks, that I really don't want to spend if I do not need to.
If I buy a Denso (nipondenso) am I buying OEM? Or which ALT should I get and at what Amperage?
Oh this is for an 1998 Acura SLX.
Is this place still alive?
