Re: This can't be good.
I'm curious how your alternator was tested? I took a couple to Auto Zone recently and requested a bench test, they punched it up and it said could only be tested in vehicle. I presume it's because they are externally regulated and their tester isn't set up for that. Either that or they don't have a compatible plug. I suppose a real shop could do better.

Re: This can't be good.
I had it tested by the shop that rebuilt it last year. He would have no reason to give me inaccurate test results. I think. He knew that I was goung to take it home and reinstall the thing.

Now, switch meter to DC volts, thoroughly ground the meter's black wire,turn on engine, and check for a 12 volt reading at the blue wire connector with your meter's red lead thoroughly contacting (you may need to rev engine a bit).Shows 11.65 Volts, running. Battery power solely.
Do you suppose that the alt is not charging, even though it tested good?
With the blue wire disconnected at the connector, the alternator CAN'T charge, so that is expected. I just wanted to make extra sure that the vehicle's infrastructure was correct and functional.
Now plug in the blue wire to the connector, engine off. Is battery terminal voltage reading 11.65 volts? Start engine. What is the voltage reading at 2,500 rpm?

Re: This can't be good.
Battery down to about 11.45 volts, but bus cranked right up. Bringing engine up to RPM's show no effect of the voltage. I have another alternator that I guess I'll substitute, and see what's up. PITA!

Re: This can't be good.
You can spin the alternator b y hand...and with meter set to lowest voltage reading...you should see some action to verify Alt is doing its thing

Re: This can't be good.
Woodruff key dropped into the guts of the spare alternator, as I was changing the pulley. I am not about to tear into the AL108,so back to the alternator guy, and have him get into both of these units. I thought I would have this sorted out today. Rough.

Re: This can't be good.
Got the woodruff key out after several hours, and finally got pulley and alternator reassembled. Tomorrow, back in the bus and we see what’s up. I love my bus. I love my bus. I love my bus.

Re: This can't be good.
I replaced the alternator with my spare, and it is now charging. What a bunch of work...I’ll be seeing my alternator rebuild guy tomorrow. I am puzzled, however, as to why it tested good in his shop. Now, of course, another issue. The cooling pipe of the replacement AL108 is a bit shorter, and does not have a lip on the end where the rubber boot slides on. So, there is more work tomorrow, as I got fed up with tearing up my hands, trying to get it on this new alternator this evening. The other unit had a much nicer, and longer cooling pipe. So it goes. Colin, you gonna take a spin down here at the end of the month, and extend the ‘17 Itinerary, into December?
