Band Aid Coil Repowering Mod question

Well it was meant for joe, but that's ok its your thread. So the standard relay the he referred to is a 4 or 5 pin automotive style. It will have male spade connectors coming out of the relay for connecting to. They are 1/4" male spade, you connect with a female of same size or preferably the mating relay socket.
The difference between a single and double pole relay is the 5 pin double pole verity will have the load connection at 2 1/4" male terminals at the same time when the relay closes. #87 & #87a connect to #30 on the bottom of the relay, a single pole will be just that, 30 to 87. A Bosch relay will also have the schematic of the relay printed on the side of it.

What I'd like to be able to do is walk into a parts store and say: "I need a Bosch _____ relay", and him to say "OK, no problem" instead of looking at me like I'm crazy and calling his buddies over so I can repeat my request for them and they all start laughing.

No eBay APP ID and/or Cert ID defined in Kunena configurationThere is no joke.
But here is the Items I would source, locally if you want.
I don't see a part # per say, but his if told to a parts counter person who is at least some what knowledgeable should have no problem, stay away from the youngsters for this.
Thanks to patton I can now embed a ebay link!

What is SPDT?

Single Pole Double Throw

Single Pole Double Throw

OK, is SPDT important for what I'm trying to do? Is there any way to dumb this down to the point that I can understand it and know what I'm asking for when I go to get one?

If I ever get the bike running well enough to take it on a road trip and I walk in the local auto store and the only one there is a pimply-faced 16 year old kid, I would like to explain what I need in such a way that he could get it for me.

DPDT = Double Throw Double Throw. I use MCM electronics wired relay sockets for relay projects:

MotorHead, this is the disconnect.

It is clear you're trying to help me.

But I have to believe it is also clear to you that what you're saying to me is over my head.

You're taking your time and giving it to me for free to be of help, but how can it help me when I can't understand it?

I'm not ungrateful, I appreciate what you're trying to do, but what is second nature to someone as knowledgable as you is not to someone as un-knowledgable as me. That's why I keep asking for clarification.

All I want to do is know what I'm asking for when I go into the parts store.

Well if you look at the picture of that relay, where it has the schematic on it, you should see 5 pins.
30 is a fused battery positive connection, then the 87 is the load out after the relay closes. 87a is when the relay is normally at rest, off, so you connect your new circuit to the relay contacts of 30 and 87. The other 2, 85, ground, and 15, Ignition switched are for the relay coil activation, this is the relay coil which operates the relay and closes the contacts. Its like you operating your light switch in your house a simple 1 connection on then off. If you had say 2 pieces of equipment that you wanted to power off 1 relay then a double contact relay would be used where 30 remains battery fused 12 v and both the 87 and 87a would make contact to the #30 when the relay is Switched on at #15 and 85.
So hopefully I was clear enough in the operation and wiring for a single and double pole. If I had a specific part # for you to ask for a O Rielly's I would give it. But you should be able to go to any parts store with the info of the relay from Ebay and get this sorted. Print that out and take it with you for reference.

OK, now I'm even more confused. That link is for a socket, not a relay.

And are you saying it should be a Double Pin Double Throw, that the ebay SPDT relay Motor Head put up is wrong?

Is it really this hard to get the correct relay for this?

What info of the relay?

That link has both a relay, single pole, and a socket on it. They have both. And on that picture there is a simple schematic of how to hook it up, as well as how it operates.
Don't feel bad if you get confused, I meet a "Mechanic" who was in the trade for 40 years and did not understand the basics of a relay, he said it was a job for an "Auto Electrician".
Stay with the SPDT relay, don't worry about the double pole stuff. Just look at the info from the Ebay link, and maybe print it, then go shopping. It would be best to have the socket for the relay, but it will cost more. As always Solder then heat shrink you connections to minimize resistance/ voltage drop.
EDIT:
Here is a link to a Bosch pdf on relays.
www.dlcparts.com/images/BoschGuide.pdf
And here is another on relay "101"
www.eurekaboy.com/f250/relay101.htm

The socket mates with the relay, being pre-wired will make completing your project easier than using individual 1/4" female quick disconnect electrical terminals.

Most sockets use 18 gauge for the relay's coil circuit with 16 gauge being used for the heavier circuit contacts.

Automotive relays available at parts stores are usually rated between 30 and 40 amps(more than what you'll need).

A relay is nothing more than a remote controled switch, designed to carry far greater currents than the light weight switches on the handlebars.
