Let’s play a game - What is this?!

Post by TheRepoGuy »



With my service manual being SEVERELY DELAYED (thanks Amazon!) I’m still removing parts which don’t appear to be “from the factory” - lots of extra wiring, fixing connectors the right way and so forth but I’ve run into another “WTF is this” part!

I posted about it before; did a little research and this is technology which I think some of the older guys (before my time, no offense I haven’t hit 40 yet but damn close ha!) might know what it is. Initially I thought it was a boost convertor but that’s not right. I’ve heard people adding this thing to increase the power to accessories on the bike but have no clue if that’s what it actually is or if it’s something else. Regardless, nothing was hooked to it so it’s been removed. Was on the inside of the left faring where I’ve got two accessory fuses a 7.5a and a 20a which also I’m not too sure about as to why they are there but I’ll deal with that later!

Any ideas folks?
Nate

It's a 12v 30A relay. Terminals #1 & 2 are the switch contacts, #3 and the grounding bracket are the trigger coil. This can be verified with an ohmmeter.

"I’ve heard people adding this thing to increase the power to accessories on the bike but have no clue if that’s what it actually is"... Partially correct - it uses a small current to control a heavy current.

That's an old fashioned horn relay. Probably last used on a vehicle in the 1960s.

I got that much - but what purpose does the damn thing serve if it’s not connected to anything is my dilemma

That's what I thought at first, but a horn relay uses a switched ground side, horn button closes ground circuit to the coil. Look at the underside of the relay, one side of the coil goes to the mount bracket and this relay doesn't provide for switch in the ground side of the coil.

Not much of dilemma, simply remove it (unless you come up with an idea for something that needs a 30 amp relay). :D

Throw it away. Not connected = not required.

Very observant of Ye. Still an ancient type of relay.
