300E Alternator Issues...

OK...it looks like I need to replace my alternator and need some advice.

Is the original Bosch 80 or 90 amp?

Secondly, I can get a reman Denso considerably cheaper than a rebuilt Bosch. Anyone have experience with the Denso?

Thirdly, do I need to know anything specific about replacing the alternator other than removing the battery terminals so I don't "fry" anything? It looks like a pretty simple job, but every time I work on a car, something always seems to go wrong...

Thanks in advance,

Bill

Denso makes good stuff. It is a Japanese company. Our Toyota has its original Denso alternator still....with nearly 150k on it.

How did you determine you need a new alternator?

It may be the brushes...BIG difference in price. It is a five minute job. Do a search!
