I am switching my air dryer out for a standard Bendix AD-9 12 volt unit. I found a 12V lead in my side electrical panel box, by the driver compartment. Must have been for something to do with the PA system whick I have removed. What I want to do it use this feed to supply the dryer and dead end my 24V feed line below. Anyone see a problem with this?? | ||

Sounds good to me, be sure to fuse it. You might be able to locate the 24 volt feed right there in the panel, and switch them over to save running another wire, if is in good shape. happy coaching! buswarrior | ||

That 12 volt connection is for the heating element in the dryer exhaust port to keep it from freezing in cold weather. Don't remember if it is thermostatically controlled. Of course, if you already know this, nevermind. | ||

I think the electric element is usually wired to be controlled by the master switch (only on when engine is running). Jack | ||

Depends on the load as to whether it is a good idea. Taking supply from the midpoint of a 24v battery can cause problems with the charging of the bottom battery | ||

I couldn't find the wire in the electrical panel, actually I should rephrase that. I found the wire but it seem to run through a series of relays controlling other valves etc. Therefore I didn't think I could simply just move the feed to a 12V source. When I dis-connected the wire that was feeding the old dryer I could hear a couple of relys or whatever clicking , so I left well enough alone. So what I did was , ran a new wire from the 12v source in the electrical panel ,fused it, installed a toggle switch to turn it on and off (it has power when the main switch is off) and then down to the dryer. I haven't tried it yet as I have to get a couple of different ends installed on my air lines, which will be done today. I was really hoping to use the exsisting line but it just didn't seem to work out. Thanks guys |
