What i'm needing is a relay that'll run off almost no amperage (the shift light circuit on the link , designed to run a LED) and switch a current of enough amperage to switch a normal 12v relay...... :confused: Any Ideas????

What about using a grunty transistor?

Jaycar kit # B197

Relay operates on 5mA

Could use a transistor to switch the coil on and off (works like a relay with no moving parts).

/edit: Oh yeah, just use a big transistor (fet)

what tricks ya got in mind?

yeh just run it using a fet..


Or a reed relay

Check with Link, that output may be able to drive the relay directly.

If you are in Auckland I know EXACTLY the guy you need to speak to.

Which is what the kit does, plus its only 4 parts on a nice easy kit, only thing is it looks a little bulky, plus its only 12 bucks

/edit: What are you planning on doing with it? NOS solenoids might need more current than that relay provides?

lol.. have NOS kick in when the shift light shows! There's fun right there..

Could it be to pull the clutch in?

Nice try guys, none of the above......
I wanna run a launch controller, but the rpm switch on the link uses the same circuit as the boost controller.....so i wanna use the shift light circuit instead. I have a shift light on the tacho so it's a spare circuit at the mo.
I'll check out a transistor then....

How would the transistor do it? Can someone draw me a diagram....I'm not that great at this electrickery stuff....

This is about as basic as you can get a diagram. depending on current draw / current flow with determine the transistor needed if that is what you want to do.

If you need a hand just sing out.

Just had a wee look at the beast. Dunno if you recall our convo at Grants Bday party, but i'm putting a puffer on my bike. And was wondering if you reacon my standard swing arm will be up to the large jump in ponys. looking at yours gives me hope after several sceptics suggested I upgrade to sumat beefier.

Since your switching something, the relay might be a better idea since it keeps the circuit seperate.
With the transistor, you need to balance it with resistors, and you may find the current draw then goes up.

If you need a hand, I'll volentar too, I have afew electrical tools that'll help too. Thanks to the boss :Punk:

Yeh you'll need a current limiting resistor at least. Was just giving him the idea. Whole thing can be build and incased for $10ish so i won't be costly.

slighty more

Would'be thought that would be just about any of them.

If you check the link mentioned before.
http://www.jaycar.co.nz/productView.asp?ID=KG9142&CATID=&keywords=relay&SPECIAL=&form=KEYWORD&ProdCodeOnly=&Keyword1=&Keyword2=&pageNumber=&priceMin=&priceMax=&SUBCATID=

You'll find that the board comes with the reistors and transitors, all in a nice pack for $11.25. So no unnecassary extra soldering
What do you think of it Affman ?

I can build it for him for half that price. But for convinience i suppose it'll do the job.

Couldn't you hook it up to an air assisted power-shifter instead?

Ring Intek security in Auckland.
They stock the item straight off the shelf.
Ready built approx matchbox size. With screw terminals attached.

It is called a "12VDC 1Amp Transistor Trigger Relay." Approx 10-15 dollars.
Quality - Excellent.

No mucking away and a reliable relay. Commonly used in security installations. If one amp is not enough, Also buy yourself a 12VDC 10amp Omron relay which is triggered via the transistor relay output. You now have a very small voltage triggering a 10amp switch.
Piece of Piss!
