2000 alpine No Brake Lights, No Back up brake

mattinmt · 09-16-2010, 03:34 PM

I have a 2000 alpine coach and have been trying to trouble shoot my hydro-max back up Brake. In the process I found that my brake lights are not working along with Cruise not disengaging. I have looked at you pictures on the forum but am confused because I don't have power at the switch on either wire. Key is on, fuses checked. I all so don't have power to the back up motor on brake booster no power to the relay. Is there a fuse some where I am missing? I am traveling and trying to trouble shoot the issue. Your insight would be greatly appreciated..

mattinmt,

Check out this irv2 link, since I think it addresses your issue:

So I have brake lights I missed the fuse. Now I am on to the back up brake motor. Any thoughts on what might be going on? I am going to switch out the relay to see if that does anything. The motor runs because I tested it.

You can test the relay by putting +12v to one coil wire & Ground to the other; you'll hear the contacts click together if relay is working, and will go from no continuity on load contacts to continuity.
Coil = spades 85/86 and these spades should read continuity (zero ohms)
Load = spades 30/87

Well I went under and unplugged repluged relay. played with the fuses in gen slide compartment. Seems to me that the fuses have to go in a certain way so I made sure I had power on each side. Played with relay some more and all of a sudden it turned on. I will keep an eye on it but I am happy. Next time the engine goes out I will be able to stop.
