Default wiring to spare on fuse block??

I have a 07' Deluxe and will be installing the Kuryakyn Grip Heat Demons.

The install instructions say to splice into Accessory circuit (ie., orange/white wire for the head light). Don't like the idea of splicing.

Originally was thinking of using the B+ Connector, which is a 10amp single wire connector. You can purchase the Acessory Adapter that can feed 2 devices of choice. One end goes to the B+ Connector, then I have to make up the male conector and attach to the Heaters (their red wire). Cost is about $20. Wasn;t thrilled using the B+ connector. The Deluxe dooesn;t have a 4 pin Acessory connector as some of the other models have. So that was out for an option.

So, I decided the best approach is to put the Heaters on it's own circuit. That way, if **** hits the fan with the Heaters, I'm isolated to it;s own circuit. There are 2 spares located on the fuse block. One has a 15 amp fuse already installed. The other is empty (and called a 15 amp spare). I plan on using the empty spare and install a 5 amp fuse (heaters draw 3 amps). Cost is like $2. So, I'm looking at both spares, both have one pin only, black wire running to it. The additional pin I'm getting from HD. Is the existing pin a ground (code for black wire)? I was expecting a red wire that is attached to +12v, then I insert the additional pin which is attached to the heater wire power(red). The fuse completes the circuit. Is my thinking incorrect?

any tips on how to properly wire up to a new circuit using the spare on the fuse block would be helpful. The manual doesn;t show anything in the electrical diagrams about the spare connections.

thankx

Just thinking only problem with this is if you forget to turn off heaters, will draw from the battery.

Any other ideas please....

There should be an "accessory" connector in the vicinity of the battery box. It can be utilized for just about any application that requires 12v power. On most bikes, this accessory power supply is controlled by a Accessory switch in the vicinity of the main power switch.

Another option is to utilize a relay that is wired directly to the battery, but is activated only when the bike's main power switch is turned to the On Position.

To answer your question directly, the black wire that you see on the spare fuses is connected to nothing. Look closely and you'll see that wire actually connects to the other fuse. It acts only as an anchor point to hold the fuse terminal.

If you plan on doing this, I would do two things:

1. Buy a Manual for my bike. Wiring diagrams are in the back.
2. Draw a diagram of what I'm doing.
3. Review that diagram with someone with 12v wiring experience. Posting it here would work too.

Now, if it's ME doing this, it's coming off a relay like stated earlier by NCCopBikeRider stated, and the power for the relay comes off the ignition switched power, or any Red with Black stripewire.

My bike doesn;t have the accessory connector. That where I started with all of this. I'm sure when these Heaters are installed, they are installed as per instructions to the orange/white head light accessory circuit. I guess this is why they want you to do this, since your are using the ignition. Would you guys be comfortable with that? Or should I go the extra step and put the heaters on it own it's circuit?

Could anyone show me a diagram of what you are talking about? I'll give it a whirl also myself...

NCCopBikeRider, are you talking about the B+ connector or the 4 pin Accessory Connector (which I definitely don;t have pn my Deluxe) ? It's a single red wire with a deutsch connector.

RJRivero, I have a manual but didn;t have anything about the spare fuses on the fuse block. Will a HD electrical manual have more info than the wiring diagrams in the service manual?

I like the relay solution. This is a fallout from my winter project of putting new Chubby 504 bars and SS cables on the scoot. So, I;m in no big hurry and have time to comer up with a good solution.

I'm a software engineer, and years ago started out fooling with digital circuits. I'll dig some cobwebs out and worse case, I got access to electrical engineers who design embedded circuits and systems. I'll ask questions and they will have me figure it all out to bust my tomaters....

But, if you got a diagram, post it up. I'm sure will be very informative to others..

The single read wire with the Deutsch connector. It is normally found in the front of the battery box area.

The wiring diagrahm in our 06 Cop Glide manual illustrates all of the circuits on the bike, with the addition of the Police Bike Supplement, we have been able to locate all of the necessary circuits.

We seem to recall that there is a seperate HD electrical manual, but will have to research that a bit more before providing a part number.

Good Luck

Yeah, that's the connector I'm referrring to. Looking at the wiring diagram, I concur that the B+ connector (10 amp max) is running of the Ign Switch (Red/Black wire) before the Ign fuse, and therefore is NONE FUSED. So looks like if if Ign is switched on or in acc position, then the B+ is HOT.

So, I guess I will use B+ connector, and get the acessory adapter. Looks like I can use something like the Bosch or Tyco SPDT 5 pin relay used in automotive. With the housing, looks pretty small to fit under seat. Need to research how to really wire up relay. I'll draw up a circuit and see what you think. I guess it will look something like:

Battery (pos) -> IGN Switch (Red/Black) -> B+ (HOT when switch is On or Acc)

12vdc SPDT Relay
+-----------------+
(cont'd) B+ -> accessory connector -> 5 amp fuse -> + + --> 5amp fuse --> to HEATERS power input
+ +
gnd <- +-----------------+

Not sure if need to fuse input and output of relay..

Let me know if I'm in the ballpark.....

Edit:

I think this covers it. The Red with Black stripe wire can be spliced from any black with red stripe wire.

You can see that the relay draws a very small current to activate an electro magnet. The magnet then throws a switch to a circuit with a higher amperage draw. The benefit is that you are only drawing a small additional current through the ignition, and the power to the grips comes directly from the battery. You can use an inline fuse to protect that circuit from the positive battery terminal, 5 amps, 10 amps, or any amperage you need to run your accessory.
