The meter may not help. If the fuse ends are corroded (especially the aluminum fuses) they may still conduct a tiny amount of electricity, enough to fool the meter, but they won't conduct enough for a load. The fuses also can have an invisible hairline crack. You need to remove each fuse, inspect it, polish the end with fine sandpaper, emery cloth, or steel wool, replace fuse. better yet, replace all of the fuses with new copper ones. They are not expensive, especially if you buy them from FastLane (click buy parts link at the top of this page, they support the forum).
