Technical coil - ?

[carl elvis]

hi,
dose anybody no which of the two wires going into the coil on a 899cc cinq is the - wire? or are they both +.

thanks carl

Light blue is the positive on both coils.

The other traced colours are the negative. The ECU switches the negative.

any idea if the "omex clubman twin coil rev limiter" would work? The instructions say to connect two wires to the coil -. would this be the other wire, not the light blue?

I think the stock ECU already has a rev limiter. Can't see the Omex over riding this.......... (under-riding, maybe).

Come to think of it, what the hell are you doing with an 899 to need a rev limiter?

i dont think here is a inbuilt rev limiter on the 899, had it up to 8,000 and nothing was holding it back. was hoping to set the limit to 6,000. just need to find the - wires and connect it up. anyone no which is the - or are they both +????

Could be that the early ones didn't. But the ECU is -- chip apart -- identical to the 1108 SPI ones.

There are two wires to each coil. Both of the ones that are not light blue (one light blue for each coil) are negative.

On the assumption that the later ECUs have a rev cut (someone will advise) then that, and swapping the chips over, might be a cheaper, simpler, option.

Assuming a sporting application, I'd go for either a standalone ECU or an advanced piggy back rather than the stock ECU (just about everything has a rev cut function).

Given a non-sporting application, I'd spend the money on something more fun!

iv just had a look at the Haynes wiring diagram and it says the coil is earthed through the body. not being great with wiring is the earth the same as the negative? here is a link to the instructions http://omextechnology.com/OMRLCLC.pdf

gaffer tape a tobacco tin to the back of throttle pedal, will limit the revs

Hi: Yes, In Autoelectrics Earth & Negative are the same thing.

so dose that mean the - is the body or the wire that isnt the blue wire???

The wires that aren't light blue are the earths/negatives, but they earth through the ECU,

What rev counter are you using?

im going to run a stack gauge and a omex clubman twincoil rev limiter.

have you ever fitted one to any of your cinqs?
