Jake Brake Problem

[Kurt Horvath]

Johnny,

Look at this post, Oslo Switch-rocker switch-dashboard on the W.O.G.
Forum. This explains a lot and would be good to check all the Cannon
Plugs for P.M. Leroy is on the right track, the Cannon Plugs sound
like the weak link in this sysytem. I have some blueprints and will
get them out tonight and let you know what I find in the AM.

suggest that if you have a master print of your coach, a huge
blueprint which shows the overall 12v electrical plan for the running
gear; it should have harness pin identifiers, mine are lettered, and
with some time spent you should be able to formulate a picture of how
it is wired. I did it on my coach for the DDECII, the ATEC, and the
DDL including how they interface. For instance pin A on the main
harness may have A1 A2 and A3 and may tie up to another harness with
different letters or numbers or any combination thereof. You have to
study it closely, but once you get it down it is relatively simple.
