Brake Light Failure

[Edward Buker]

Norm,

Not sure if this will help. This is a diagram for a two switch Jake Brake arrangement in the upper right of this Cat C12 engine wiring diagram. If you omit the on off switch and just have the 3 position switch, it must be that the center position on the switch is an open position like you would get with that on off switch set to off. So high and low position wiring would likely be connected in a similar way as this switch is while in those positions.....at least a good guess.

I do not know if you have a switch wiring error or a real wiring issue. Hope in some way this helps.

Norm,
In the Members Only Coach Assist section there is a wiring diagram for a 2003 Patriot Shifter Panel; 46030016_19. Switch "C" is the Jake Brake switch. From the symptoms you describe, I suspect that the Ign Pwr wire (#300) is hooked to one of the end tabs on the switch and not to the center tab as is intended. This could result in Ign Pwr always being present on the Eng Brk Switch Out wire (#418). Not sure if the wire numbers are the same, but in any case you could use a meter to determine if you have 12V on one of the center connections of the switch. That should be the only 12V signal present if the switch is Off. If you've got 12v on any other switch connections, you've probably got a mis-wire.

Trying to get a view of the various wiring diagrams on the Coach Assist portion of the BAC web site but can't find where to log on.  I know it's got to be obvious, but it's one of those days.

Norm, you shouldn't have to log on if you are already logged in here.  The link is off the Private BAC Members Only section on this Forum's Home page - you just have to go through a couple links enroute.

Norm,
I'll try emailing you the diagram.

Time for an Update.  First, I want to thank all of you who provided me with numerous suggestions and copies of wiring diagrams, that's why I love this forum and BAC.  Now for the update.  I called Ken and BCS yesterday to see if he had any ideas of copies of additional wiring details.  I described my problem and he provided me with several things to check.  He also suggested that I might contact Jason Gerke at Monaco, 877-466-6226.  After working on the coach for a few more hours, and going thru several more fuses, I lost count, I gave Jason a call.  He was very helpful and patently discussed the various components I was dealing while he pulled up various wiring diagrams on his computer.  Through our discussion, I realized that I had mad an unnecessary connection.  In my attempt to make sure all the connections were correct, I had mistakenly connected a coupling that supports a floor operated engine break switch, which I don't have.  Once I unplugged this connection, everything worked.  As usual, it is the obvious things I overlook in trying to solve a problem.  Thanks again for all the input.

Great news Norm. Glad you can cruise again.
