HID

[RedRider]

Spike13 stopped in this afternoon and we installed a 10 second on-delay relay for his HID. We first tested the relay with an old battery since I wasn't exactly sure how it worked and the wiring diagram wasn't the clearest. The delay relay was a 5 pin relay while the currently installed wiring harness relay was a 4 pin relay.

 

After testing, we concluded the relay should plug right into the 4 pin socket and work. And...... indeed it did.

 

Turn on the key, and start counting. 10 seconds later, the light comes on. Plenty of time to get the bike started. Worked like a champ.

 

This is the time delay relay we used.

Yea it can be done in a few hours. Depending on if you want to put a switch on it or the time delay relay deal. The switch option takes longer as you have to have other parts for the switch and LED warning light etc. Now I see the relays are pretty redaly available I think thats probably the best option. This is same unit I have. There are some US sellers for kits and about $10 more and no relay harness.

I am interested in doing this mod. I'm not an electrician, but if I have a diagram I usually do just fine. I installed the passing lights yesterday, and I ended up using the instructions that came with them to install them. I bought a relay, and distribution block, but didn't use them. After seeing this, I might hook up the delay relay, and distribution block. I am posting a picture below. What if I use this set up, only replace the regular relay with the timed relay? I can still wire in the toggle switch for the passing lights, and wire the positive, and negative headlight wires into the distribution block. Any thoughts? Will that work?

 

Edit: I used the red with yellow stripe lead for my power soure for the passing lights. I would use that also instead of the running light for my switched power source for my set up.

 

Here is the picture.

This is a nicely done diagram. The wiring as is should work fine. However, a couple of thoughts here.

 

1) The pull from any of these loads is either proportional to voltage (heated vest / grips) or very small (GPS / Radar detector). None will affect the starting circuit nor will the starting circuit affect any of them.

 

2) Each '+' line coming off the distribution block should be fused.

 

3) Wiring would be simplified by using a fuseblock (FZ-1 from fuzeblocks.com is the one I like). There are several others out there.

 

4) Per #1 above, it really doesn't need a time delay relay. A standard relay will do the same thing.

 

The reason we put the time delay relay in the HID circuit is that an HID pulls about 120 watts (approx 10A at 12V) when it fires up. Also, the circuitry in the HID igniter has internal protection that shuts it off when the feed voltage drops below a certain level (ie. battery voltage drops to far). The high current draw required to start the bike will sometimes pull the battery voltage down below this threshold level and kill the light. Sometimes it will reignite, sometimes not.

 

HIDs do not like to have their power cycled without cooling off between starts. IIRC on first gens the headlight power is interrupted when the starting circuit is initiated (starter button pushed). If so, this will also quickly cycle the power on the HID. Again - bad.

 

Bottom line - Your wiring should work (add the fuses). Time delay isn't really necessary.
