400 ISL starter positive cable routing revisit
I documented my starter issue this past week in another thread. Thanks again for everyone's help.
I also posted a picture of an insulation failure on the starter positive cable that I found while trouble shooting what turned out to be a failed terminal on the starter solenoid. I'm attaching the picture again. On my coach, the cable was routed in a loop up and over to the top of the starter. In doing so, it was centered in the 5" to 6" of space between exhaust manifold and the turbine exhaust. So it was constantly getting blasted by heat from two sides. It is fairly easy to see from the top side of the engine and I first saw it from the bottom, so it can be seen from there but it is harder to get in position to see.
I strongly recommend all 400 ISL owners check for the same insulation failure.
On my new starter, I was able to route the new cable out the side and down so that it only has to deal with the turbine exhaust pipe and not the manifold.
Hope this helps someone avoid a similar problem,
Rich
