Thanks much John. I was hoping to hear from you. Your response was exactly what I was thinking but I needed a little confidence about not damaging the TIU.
The layout is a 7 foot dogbone with no accessories and one engine at a time so the Sound Button shouldn’t be overloaded. That said, Im planning to upgrade the leads. I realize that doesn’t address the internal diodes but I want more flexible wires anyway.
Thanks once more for your time and expertise.
