I'm trying to kill some noise in my system and I need to buy 4 <10ohm 25W resistors. RS want £6 p+p, Farnell £12! I'd rather not wait n weeks for them to come from China via eBay. Maplin don't seem to do them in that wattage. Is there anyone in/around London/Hertfordshire that would sell them over the counter?

Regards,
Dave

Farnells have something like a £25 min order

there's cpc which is farnell but they only want £1.31 each - odd

Would Cambridge be any good? There is a small old fashioned electronics shop at 94a Mill Road, Tel 01223 358019

Any good ?

Hang they are based in China...

RS components do em. rswww.com

These want a fiver for a pair? maybe worth a call??

Can you elaborate on the plan and be more specific with the resistance you need?

I'm suffering from electrical noise with my MS. Following http://www.extraefi.co.uk/resets.htm I'm effectively converting my low impedance injectors to high impedance ones. They currently measure 2.7 ohms. ExtraEFI site says 3 to 6 ohms, megamanual defines high impedance as > 10 ohm, so I'm aiming for somewhere between 6 and 10 ohms.

Cool, I will have a look tomorrow, I may have something

I had to do the same on my first mega squirt installation, I used some resistors from RS and didn't think they were very dear.
Some older cars used a resistor pack for the same purpose maybe Volvos if I remember correctly.

I had a similar problem with omex plus ex cossy injectors which were low impedance. Tried the resistors but they still fired erraticaly above 4000 rpm. Eventualy bought sme secondhand high impedance injectors and problem gone.

On the advice of Phil Ringwood, I bought 4 25W 6.8ohm resistors from Farnell. I was a little aggrieved about the £20 min order, but I'm up a new soldering iron now. Ordered 19:35 Monday night, they arrived 3pm Tuesday, I was impressed by that.

Finally got around to fitting them today and from some initial testing I haven't been able to provoke any odd spikes in my data logs. I'm a happy bunny
