Here are a few things to check to determine if you need a new trim Pump.
- If your trim pump is not functioning, you will first want to check the trim pump fuse by the batter
- If the trim pump fuse is okay, then you will want to bypass the trim switch to verify that the trim pump is bad. To do this you will apply 12V positive to the small blue wire and see if anything happens. Then to the same to the small green wire on the solenoids. The blue wire makes your trim pump pump in the up direction, The green wire makes the trim pump pump in the down direction. If the trim pump still does not work there are a couple of possibilities. If the solenoids were clicking, then it is possible that just the motor is bad. If the solenoids were not clicking, then most likely the solenoids are bad. It is unusual for both of them to be bad, so you may want to check to make sure the ground for the trim Pump is good.
- To determine if the trim pump motor is bad you want to apply 12V positive to the large trim pump motor blue wire first, and then to the large trim pump motor wire. If you have no response or a large spark, then the trim pump motor is bad or the valve body is locked up. You can do this same check with the trim pump motor removed from the valve body to see if it spins.
- The trim pump valve body is not designed to be serviceable, so if it is bad we would suggest replacing the complete trim pump.

Nice Fit
Color: Black, White, Light Gray, Size: 3X-Large
I picked this up looking for something simple but clean, and it delivered. The fit is comfortable, the material feels solid, and it looks good without needing much effort. It’s one of those pieces you can throw on and still look put together.

Good value, soft and comfortable
Color: Black, Army Green, Light Gray, Size: 4X-Large, Color: Black, Army Green, Light Gray, Size: 4X-Large
Initial thoughts are very positive with this 3 pack shirt set. The green is similar to an OD military green and the black and gray are standard color shades. Material is soft and sizes are true to size. The mock turtleneck isn’t too tight but may still be a little annoying to some people. I do question the amount of spandex in these shirts. Tag says 5% but these shirts are extremely stretchy and feels like a higher spandex content. It’s also a little tough to figure out which way is the front of the shirt. Visually rhe front does have a lower collar line than the back but would still be nice to have a brand tag printed in the back of the shirt for quicker identification.
Overall for roughly $12 a shirt these are a good choice for everyday wear. I will update rating if these shirts fail to meet expectations after further use.

Just what I wanted.
Color: Black, Navy Blue, Wine Red, Size: 5X-Large
These may have just become my standard shirt to wear. Feels good whether tucked or out. Drapes well and fits well. So far, I can see it adjust to the different undershirt I may wear. Will probably order another set in other colors and a back up set of the basics because they will get worn a lot.
