[V8] 1990 V8q not charging

[Tony and Lillie]

Check the blue wire going to the alternator with it disconnected. I actually 
cut mine and put a waterproof connector on it so it's easy to check. 
Otherwise, you have to remove the rear cover, which is a bit of a PITA. The 
8mm nuts are usually rusted in place :(

It should have battery voltage with the key in the run position.
