Getting closer on the engine swap, now I have some electrical questions Mike is asking me and I need help to answer him.
The Cummins ECM, ZF transmission ECM and shift pad are all 24v. On the shift pad, a 10a 12v - 24v step up converter will work, but I'm pretty sure the ECMs will be drawing more amperage than a $15 step up converter is able to handle.
Right now, the coach has two 12v starter batteries, I was wondering if I could wire them where I could have 24v in the engine bay for the ECMs and keep my 24v alternator and 24v starter?
Any help would be appreciated!
