Direct replacement for Cessna starter solenoid. The original had on three connections, the ground connection was simply the case. This version did not pose any installation problems, the ground wire was included and simply connected to one of the mounting bolts.

worked great. Had a question on how to install. There are two different ways to connect one of the wires that comes with it. Called the Lamar company for technical information and they helped out. Great product.

This part did not fit the spacing of the bolts that mount it to the firewall of my C-205A even though this part is authorized for this aircraft. If your bolt spacing is 2 inches, it wont fit.

Purchased this to replace a 55 year old part that was still working, just showing signs of age. Worked great for 13 months (one month outside of warranty), then the solenoid stuck on and caused battery failure.

This product fit in the mount and to this point accomplishes the intended task at a fraction of the cost of the OEM part.

Installed easily. Fit the original footprint and post layout. Starter spins better now than I can ever remember. First rate product.
