Horn repair
No sound from my aoogah horn, so will disassemble, clean, and reassemble per Les Andrews. His sketch shows two felt oil washers on the motor--one at each end. Mine had only one, and I lost the other during disassembly. Is there a common household product which could be used to create new ones--old felt hat, Sorel boot liner, etc?

Re: Horn repair
One more question--instructions say to clean field windings with compressed air. Any reason why I can't use solvent?

Re: Horn repair
Yes, depending on the solvent you use it might loosen or remove the installation on the windings. If so then you are SOL, and the windings will need to be replaced.

Re: Horn repair
Mass airflow sensor cleaner so far hasn't eaten any parts I have tried it on, use it to clean contaminated transmission computers

Re: Horn repair
And please follow the advice Andrews gives about being gentle with the armature. I wasn't, and one of the wires broke. I was lucky to find a rusty but working horn on an auction site, so I put its armature in my horn and I'm back in business.

Re: Horn repair
I am being very careful. The wires appear very fragile, and I don't wish to break any of them

Re: Horn repair
This is what a bad horn looks like. I bought a new one from A&L before the pandemic.

Re: Horn repair
Update- Followed all procedures, reassembled horn, and it works, but it is not nearly as loud as it should be. Maybe it just needs adjustment, but Is wire size a culprit? I tested it with ~14 ga jumper wires

Re: Horn repair
Any voltage drop is a problem for the horn motor.

Re: Horn repair
Probably adjustment. Maybe worn ratchet. #14 is plenty.
