Thank you!
I actually have the service manual downloaded to my PC. I'll pull it up later and find the relevant section to print out.
Thanks for the advice, much appreciated!
What do i use to drive the old bearing out and the new one in? Just a couple of appropriately sized sockets and a mallet? (I'm just guessing, I haven't even looked at it yet).
Since there was no core required for the new alternator, I may try and repair this one and keep it as a spare. I've never changed one of these bearings before. Not even sure i have the right tools to do it.
There is under one of the terminals (the one that will still accept a spade connector), the other one has a metal washer under it, which grounds it. It appears to be fine. I installed it this morning and it's charging without the bearing racket.
OK. Now I feel like a complete idiot, but I guess this is how we learn. I was measuring using the screws on the brush terminals, thinking they were the wire attachment points.
I retested using the brass terminal and found the following:
The insulated brush shows 5.5 ohms to the case, and the...
I just rechecked, and both field terminals read 0.4 ohms to the case, and the Bat+ is showing approximately 1000 ohms to the case. Resistance between the two field terminals is 0.3 ohms.
So I guess I have an internal short.
I suppose it was a good thing I checked!
My 67 Monaco is in need of a new alternator, the bearings are shot and it's growling something awful.
I purchased a reman unit from Napa Auto that is rated at 60amps (squareback), so unlike my current alternator, it has 2 field terminals. I understand I just need to ground one of these terminals...
