Fitting an HID kit - wee query.

[Posh Pete]

First serious bit of bling to the 11RT - an HID kit. I bought a car kit reckoning that the spare ballast and bulb would come in handy.

Got the bulb in this pm. A bit of a double jointed gynaecologist job getting around the fairing and instrument panel on the RT!

Tomorrow's job is to finish fitting the relay and the ballast with one slight snag already: the relay harness does not match the set up shown in the instructions.

Here's the harness I got ...

(Sorry about the size of pic from my phone.)

From top to bottom...

1. The battery positive lead and fuse. (I'll be extending this to reach the battery.)

2. A connection to one ballast and (I assume) an earth.

3. A second ballast connection and earth. (I'll simply coil this up, zip tie it and stick it in a freezer bag to keep it clean)

4. The connector to the bulb power lead on the bike.

Problem: there's no separate connection to the battery earth as the instructions seems to suggest.

Do I simply extend the earth connections from the ballast I'll be using to the earth on the battery? (Rather than earthing to the frame near the headlight which might cause earthing problems in the future.)

Over to you o wise ones ...

1100rt HID kit

Your details are scanty, & your photo worse, but:
I used to own an 1100rt,, but have forgotten the lamp style:
is it H4 or 2 x H7?
Are you fitting auxilary lights or modifying the headlight?
If you are just modifying headlight, you do not need a relay (H7)
If you have a H4 lamp, you need a relay (or a bridge rectifier)
In neither case do you need to connect any cables to battery.
If you inform me of what you are fitting, I will post a wiring diagram.
If you are fitting auxiliary lights, a relay is required, with 12v+ to battery via fuse.

Is that an H4 HID? I am running a car HID on my 1100, I connected positive to the battery + and one of the earths to a handy bolt on the frame then the connections to the Ballasts and burners were separate pairs, I just left one of them in a plastic bag and tucked it away and connected the other, the only other connection was basically a dummy H4 connection which plugs where the original bulb connected.

H4 Bi xenon

Yep. H4 right enough. Thanks for confirming my inclinations Stewart. I'll take an earth back to the battery tho' to minimise voltage drop.

Just find a bolt and bolt it down, the steel/alloy of the bike is a better cable than you can add to what you have

Voltage Drop?
What are you worried about?
First of all, the original light was 55/65w, the replacement is either 50 or 33w, so there is already a lower load.
Next: Because of the ballast, the voltage is irrelevant. Light output does not vary with voltage as it does with a filament lamp, where light output goes up as the square of the voltage.

Since you are on H4, did you buy a dipping H4 lamp?
These ones have a small solenoid in them to move the lamp forwards & backwards from main to dip beam.

Many H4 kits leave you with a dip beam only because they do not have the solenoid, and the ones that do tend to have terrible focussing problems, leaving them marginally worse than conventional filament lamps.

If a bridge rectifier is used with these, correctly connected, the relay is unneccesary, & original wires just plug into bridge rectifer & then output to Ballast & Solenoid.
If required, I will post drawing.

All done now.

After a glitch that had me puzzled for a bit, all ok now. The glitch ... you'd have thought after years of working on BMs that I'd remember which side of the battery was live and which the earth ...

Old age doesn't come itself!!!!

Are you waiting for it to get dark now?

why not add additional driving lamp instead???
isn't that an easier option?
