Electric help (Too many gadgets!)

[chris-red]

Right Currently I have 4 things attached to each Battery terminal on my TDM.

I have
Air Horn
Heated Grips
Cigarette Adaptor
Loom

I want to attach a optimate adaptor to it as well but I think it's getting abit silly. I want to rewire and tidy it up, I'm looking for ideas how to group the lot together I only really want 1 extra wire coming off each battery terminal. Any suggestions?

Trip to scrapyard and pick up a cheap fuse box.
Find another thick cable to go from battery to fuse box, then rewire all from that fuse box.

Could you not just adapt the optimate to go to the ciggi adaptor..

The way it's generally done is to wire everything in [not serial, parallel - Edited for stupidity].

So have a wire run from the battery to the air horn*. Put two wires into the crimp terminal for that. You now have a loose end of wire. run that to the fag lighter, again, two wires into the crimp, run the loose one to the hot grips. Use fat wire and big crimps

* via a single fuse of sufficient magnitude to take the load of all the accessories, obviously. Also you need to be careful you don't have the optimate powering anything, so everything on that wire needs to be switched. In fact, you'd be much better taking the accessory wire from a switched supply(e.g. at the fusebox) than the battery terminal. The optimate then goes straight to the battery.

You would be best adding a second fuse box.

Some cheap ones here.

I use my power socket to charge the bike, just a case of plugging it in if needed then as it goes directly to the battery. No extra wires needed then.

Air horn as said should be directly from battery(fused) to cut any loss in power.

Best thing would be, as you said, to rewire and to add another fuse box.

Look at some of the BMW touring sites or search my-mc.com (search for "fuse box", you get links like this) for ideas.
The fuse box you want is one of the waterproof ones used in boats (marine suppliers/chandelers), bright yellow if I remember.

Wire into a live feed, put a fuse on it with a relay. Then wire your electric gadgets from the fuse box, fitting other relays as appropriate.

How would I split the single wire from the battery though?


The air horn is on a relay, everything is fused individually.

get the multiple wires , trim the ends and twist them together creating one wire

looks messy but does the job and can be covered up with insulation tape

I don't really see the problem with having lots of accessories bolted to the battery terminals. Incidentally some batteries have two screws on the terminals for this purpose.

Sure, it probably makes a bit of a birds nest, but if you're anything like me you probably disconnect, replace or upgrade accessories frequently. Any kind of custom-made wiring harness is going to be a waste of time and effort.

If it's just a nuisance because you have to line up 5 rings each time you d/c the battery then consider soldering the rings together into one - quick, simple and temporary.

You could also consider earthing some of your accessories to nearby frame or engines bolts or other parts of the bike, rather than the neg terminal on the battery. Make sure you do this after any relevant switches though.
This would just reduce some of the birds-nest effect under the seat.

but i couldnt be bothered to type all that

[chris-red]

That block looks useful, where would I get one from?


The problem with having all that shit attached to the battery is that it is really difficult to screw the terminals to the battery as all the connections mean the screw only just gets in far enough to pick up the block.

As others have said, a fusebox would be best. Then each device is individually fused.

Hi

Simplest solution would be to wire a few of the items to the terminal for the starter relay (the terminal connected to the battery).

Earths are easy to find.

All the best

Er, yes, I did mean wire them in parallel, description was right though I think what I meant to say was wire them in series, which is different.

You can wire it as I described to avoid unnecessary "T" type joints and junction boxes etc. Also, there's no need to negative run wires back to the battery, just to the frame by the nearest earthing point.

Several things you can safely tap off other circuits to save wiring to the battery. I run exactly the same equipment as you. Heated grips are powered directly off the low beam feed, they only draw about 30watts so are well within the limits of the wiring guage and the headlight fuse.

The cigarette lighter you can run off a thick guage wire to the battery, you can split this wire into 2 further away from the battery and have one go to the air horn relay to save 2 seperate wires onto the battery terminal, just make sure the combined current draw off all circuits doesn't exceed the guage and fuse of the single feed from the battery. So if you have an air horn pulling 20 amps and a cigarette lighter maxing at 20 amps and you join the wiring before the battery, the wire to the battery must be 40 amp while the 2 branches can be 20 amp each, if doing it this way you're best off fusing each branch rather than the main wire.
