Mark, how do you know your solenoid is working properly?? It can be very tricky trying to test it. They can work but poorly. For example, they may not work if you need to boost your batteries when starting. The contacts become contaminated and resistive. As a comparison think of it as a fuel filter that is dirty but still allows you to roll down the road under normal conditions. Now you try to go up a steep hill and the fuel filter cannot deliver the extra load need and you have issues. The same can happen with relay contacts. They may not be able to deliver the load.
I just thought of a way to test them. We should be able to turn the engine battery off and then try to start it through the aux start function. That would put a huge load through it. If it turns over and starts normally then the solenoid is fine.
