Im thinking I may have lost my alternator yesterday ... not sure yet.

Would it throw a code on the dash if it wasnt charging?

Usually my voltometer reads way higher than I expected it to ... around 15v (between the middle and 18v) , today its hovering around 12v (between 8 and the middle). Could the high reading be a warning sign of a failing alternator?

I smelled a weird smell from the passenger side front of the engine. Definitely an electric smell kinda like rubber and plastic. It was strong enough to notice with the hood down. I wasnt hearing any strange noises though yet.

It could just be that it was 95 degrees out today here ... but its definitely not usual. The battery is a 2 year old Odyssey, I dont think I am having issues there ... all the connections are tight.

What should I look for or keep an eye on? I thought I noticed a thin wire that was cut in half , but it looked to have been that way for a long time untouched around the passenger fan area ... lots of squirrels around here.

I was told to test the battery voltage before a start, while running, and after turning the engine off to see if its being drained? Also a magnetic charge to the back of the alternator if its charging, but thats not really possible in our vehicles.

Do you guys recommend I just take off the throttle body forward, or loosen the plenum/pull it off? Someone mentioned both things to me. Seems like its going to be the most pain in the butt alternator swap I have done?

I may as well throw a new belt on there too, is there a recommended brand? How about throwing me the number if you have it on hand.

I drive the car weekly. I guess I'll know sooner or later if my battery gets drained LOL.

Here is the alternator I was thinking of replacing it with, a 200amp rebuilt Bosch unit. Does this seem like a good choice, the price is reasonable:

Just making sure but the 91-95's use the same alternator as the 90', right? This one says it is compatible with my 90, but lists it as a 91-95.

Thanks for the advice ---
