Making a good earth...

[mr.z]

Finaly got arorund to fiting horns to the third bike they will have been on

Runs off a 20AMP fuse, so its a fair bit, its going to be off a relay and have + running from the batery to relay..

Wanting it to be tidy + it being a high current, whats the best way to make a good earthing point, say off a bolt hole onto the frame?

I know its simple stuff, but i've done smaller bits beofre which didn't have a good enough earth and want to clarify what i'm doing is right

Tap the hole out to make sure theres no paint in it, sand the nut head to remove all rust or paint, degrease and then for overkill use conductive grease. Same for terminal and bolt.

Is 20amps a lot for a horn?

Yep, your 20 amp current will be through the heavy contacts and earthed at the load (compressor), the current for the actual coil in the relay will be negligable. But you'll still need a 'good' earth for that.

Air horns by any chance?

if so your as daft as me with the neons

Yep, they are there to heared not seen

The horn isn't very effective and have needed to use it a couple of times this summer, so thought i'd get off my ass and sort it out...

Sounds better than the frightend mewing kitten horn

neons... saw the pics, not over the top (not my thing) but nicely done (dont do any more though ) will help you be seen at night and are fairly legalish...
