Magnum Chassis

[jtkempe]

I have a 1999 Safari Sahara, 35' with 1 slide. I've been having trouble with the modifications the coach portion of Safari made to the Magnum portion. The wiring is marked every few inches, but how the different functions work has been frustrating to say the least. My latest mystery was when the Hadley Air horns and step cover quit working. The Safari coach folks added a additional relay so that the Pac-Brake compressor furnished air to both the Pac-Brake system and filled the reservoir for the horn and step cover. After a commercial repair job ($$$), the system worked for a while then quit. I have split the system to a compressor for the reservoir, and a compressor for the Pac-Brake. I would like to find out if the clipped wires going to the chassis relay could be re-connected. Currently the compressor for the Pac-Brake is turned on with the ignition (I suspect so that the reservoir in front would be filled) and remains on. Any written info on the magnum chassis functions would be helpful. I was able to get the coach wiring schematics, DC and AC, at a old Safari rally which has been most helpful in trouble shooting those particular problems. Chassis electrical problems have been another matter. - Jon

Jon,

Welcome to the FMCA Forum.

I am not sure what you are asking. It sounds like your compressor(s) are wired correctly, with an ignition hot used to activate the relay to supply battery power to the compressor. As long as the compressors are wired this way (using ignition source only to close the relay), you can gain ignition source from virtually anywhere, as you are adding less than a one amp load.

Thanks for the info. Still hunting for schematics of the chassis.

JT, you might want to hop on over to the Safari Website ( http://autos.groups.yahoo.com/group/Safarifriends/ ), we have a lot of useful and downloadable files, especially wiring schematics.
