Good resource

[tugboater]

I’ve found this book very valuable. Many of the systems in a boat, both pleasure & commercial, are similar to that of what we envision in our busses. I don’t know of an electrical handbook for bus conversions... this is the next best thing.

There have been a few books on wiring bus conversions, but not recently. Now they're out of print and, if you can find a copy, very expensive.

I looked at everything the Amazon search engine found under the keywords: bus, electrical; a total of 36 pages. All I found was one ebook of an older book. There was also a used copy of the same book that someone was asking almost $800 for on Amazon.

But upon reading reviews and comments on that ebook it became obvious that all the illustrations were lost in the conversion process, so the author's wiring diagrams are gone.

The book you recommend is available through Amazon, used or new, so that means it's elsewhere too, and probably the best book available now.
