Yes Randall I have tried to contact Monaco but due to there merging with Navistar technical data is limited. Latest contact information was that they couldnt retrieve any updated prints for that model and year coach. Wiring was changed in 2004 from previous years. Maybe this will help. Last six of Vin# XXXXX Last six of S.N.#003630. Not much help on Monaco end.

I don't have anything else that would help you. My first thought is that this may be a ground issue. As you probably know, many times these things are a bad ground. You may be correct that the signal does go though a relay or controller of some type. Does this unit have any kind of switching hardware made by Intellitec? Many of their products also contain fuses and boards. If so, take the cover off the box and see if you have a bad fuse or a relay out. I can get you a link to one they use a lot if you don't have it. Go HERE for that. Notice the fuses. Let me know what you find. R.J.

Turns out Randall that flasher relay was not allowing enough voltage through to engage turn signals or indicator lamps on dash. Flasher relay was working but voltage was low. Replaced flasher relay and all started working properly. I could not see this problem with a test light. Used multimeter to diagnose. Thank you for your prompt help in this matter. Its repairs like this that makes me want to throw my test light away at times. Lesson learned.

Test lights only show that you are getting you well know. Glad you got it resolved. R.J.
