Air Horn Solenoid - I need an exploded view or TM ref

[DrFoster]

Ok - I've been on here for over an hour browsing all of the M35 manuals, and I cannot find a single view and parts content of the air horn solenoid.

I'm trying to troubleshoot mine, and it clicks when the tanks are drained, but not pressurized. I took it apart and all it has inside is a single plunger. I'm thinking it is missing something... maybe a spring or arm? It just looks too bare. After I took it apart and lubed/replaced everything it either stays on or doesn't turn on at all.

Does anyone have a reference to a TM I have not seen, or a photo of theirs that is disassembled so I can examine whether or not I need to just go buy a new one?

Hey, the good Doctor is in the house!!!

Where ya been Doc?

I think the solenoid is a non-servicable item....

 

[ida34]

Of course it is not servicable. It does not work. Or did you mean the item can't be serviced?

 

[DrFoster]

ok - is there a replacement out there? Saturn shows one but it is sold out and looks incorrect anyhow.

Anyone have a spare - or a junk replacement horn set?

Repair procedure for airhorn solenoids:
1. Remove.
2. Wing it into the corner with the blown fuses, burnt out light bulbs, windshield wiper blades missing the rubber, shocks leaking oil, etc.
3. Replace with working solenoid.

It should have a spring to hold the slug out of the magnet coil. 24V to it pulls the magnet into the coil, opening the valve. Spring broken?

If by some wierd design it is held 'off' by the compressed air, then the coil could be open or burnt out? What is the DC resistance of the coil?

These people sell a 24V solenoid valve, as well as all kinds of horns.
