Train horn troubles

Ok i got my OBA and horn all set up and it worked perfect just the way it should...come out to the truck this morning...and the truck is dead

This is the setup i ended up using


Instead of the wire connected to the distribution box i ended up using fuse #27 in cab fuse box but i didnt actually have it hooked in overnight because i ended up needing an add-a-circut before i could actually install it and i was gonna do it this morning before work so the wire was just sitting between my floormat and the carpet so it wasnt grounding out or anything.

So i guess where do you guys think the draw is coming from because it totally drained my batteries from 7pm last night until 7am. So in 12 hrs it drained my batteries completely so its obviously a big draw.

First, was the tank empty when the batteries were dead? Could you have run the compressor for hours & hours? Because No relay or solenoid should be able to consume enough of the batteries reserves to kill them...

Maybe this is unrelated to the horns?

Also, isn't the horn sw, in the wheel, one that supplies Ground? (I wired mine differently, through a relay, at the wire going to the electric horn so I could switch between them)

Well my luck is it would be the day my gf left her door open or something but i didnt check the tank but the power wasnt even on to the compressor because its key on power not constant.

as for the solenoid/horn switch no theres two wires that run to the stock horn and i just snipped them and ran them to the solenoid so when i hit the horn it activates the solenoid

Train horn troubles

I'm no expert by any means, but, at the horn, are you on the ground side? I plan on doing train horns too, just want to make sure all the problems are worked out.

As far as the diagram goes it works perfectly as i wanted it to but im guessing i have something shorted or something stupid im missing. But when i first got it finally together it worked just as planned and i drove around town all day no problems

Train horn troubles

Keep us posted. If you're driving, it would be fine but it does sound like there is a constant power draw. I've heard that with the horn switch, it activates by using the ground side so if your are on the positive side, it may be constant.

The side that activates shouldnt matter right because its still a circut that only is hot when its completed hot to ground

Again, any draw that would drain those batteries overnight, if good, would be More than any interior light, solenoid, relay, etc. can supply. As for a short, you'd melt almost any of those wires that be in a direct short. You have to remember the reserve those two, high capacity, batteries have!

It's either unrelated, you have bad batteries, or a pretty significant draw to do that...
