The solenoid might have 4 terminals. Two for the heavy cables and 2 lighter ones. The white wire, on a Craftsman, comes from the switch and goes on one of the terminals and the black one goes to the other terminal. The solenoid might be marked S for the white one.

Without a picture and/or knowing anything else, my best guess is whiteflies.

Some atachments are very pricy and if you use the strainer atachment, its use is usually limited to just tomatoes. Seeds of smaller berries are going to jam or go through the holes. The strainer as no optional sieves. My old Oster Kitchen center as more stuff for cutting and slicing that I used all the time, especailly the slicers, and grater disks, not to mention a food processer. The KA seems to have wire wisk beaters which tend to make you use a spatula to clean off the sides of the bowl all the time. The Oster has an offest beater and goes against the bottom and sides while also rotating the varios bowls. then there is a blender atttachment as well as an ice crusher, and ice crem maker that uses the traditional rock salt and ice. Its no longer made, but if you find a used one, grab it, try it out, and I am sure it will become a necessary device for many food prepping issues. If they were to atart making them again, they would probably outsel any other multifunctioanl product, proved it was advertised well. Now Oster/Sunbeam are Jarden owned, who also make Food Saver, and many other products, as well as all Ball canning supplies..

The leaf roll could just be physiological, meaning just something that happens as a response to stresses like hot weather, underwatering, overwatering, etc. It sounds like your watering regimen is fine. Based on the information you provided, the most likely explanation is that the leaves turning yellow and purple because of a nutrient deficiency. Alaska Fish Fertilizer has nitrogen (N), but not much phosphorus (P) or potassium (K), and I have no idea whether it has many of the other nutrients, such as Mg and Ca, which tomatoes need. It's a fine fertilizer for leafy green veg, or for tomato plants when they're young before they start to bloom, but once they start to flower and fruit, they'll need more P and K than N. I would suggest you get a liquid fertilizer specifically for tomatoes or at least for fruiting vegetables, and try that and see whether your plant improves. There is a chance that your plant could have a virus, though. Keep a close eye on new growth. If it appears very curly and distorted and/or develops fat, purple veins or turns very purple on the underside of the leaves despite fertilizing with a tomato-appropriate fertilizer, and if the newer flowers start looking weird, it probably has a virus vectored by whatever pest caused the damage in the first pic (looks like leafhopper damage to me, and based on that and your location, I would think that Beet Curly Top Virus would be a top culprit). If it turns out that your plant does have a virus, it should be pulled and discarded. Here's a fact sheet on it with some photos which can give you an idea what to look for. Note that the distortion with a virus will be more dramatic, not just the rolled leaf edges you have now. Your local county extension should be able to help if you're unsure about a diagnosis. But don't panic yet. I think it's more likely to be a nutritional issue + heat-related stress.
