Hi, anyone have picture or diagram how to fix the wire on the Hrc Rs250 spark coil onto Nsr Mc28. My worries the wire colour which connect too.. Thanks ..

Any help.. ????

You're fitting non standard race parts to a road bike. I think you are going to have to work it out and share your info once done!

If it were me, I would take some readings off a stock coil, and compare them to the HRC coil. For example, measure the ohms between each "spade" terminal and the HT lead, noting which gives the higher reading, and then measure the resistance the same way. Redo the tests on the HRC coils, and look for a pattern. That should indicate which pin is the "signal" pin.

Remember to take a fork off the ground side to ground the body of the HRC coil.

Of course, if someone with an RS to hand can have a close look at one of their coils, and post a description or photo, that would be really handy for you. But you don't even say if you have NF or NX style coils. It's kinda hard to help someone when you don't give all the info!

Well the packing stated HRC parts..but the brand if the coils is tec. Its funny that the coil connection pins did not indicate any colour code but im gladly you give a good advise. But later i post the parts number.

I have the coil parts number. Its a 30510-NX5-701 and 30520-NX5-701. If someone have done or knowledge which side the earth pin that will be very great help.

I'll see if I can grab a photo tonight. Mine has RS coils on my 21. From memory an additional earth was required.

Or you could trawl my build thread in the members section to see if there is a photo.

Greggo that will great, really need your help or anyone that solve my problem.. currently im stuck in this situation .
