Is there such a thing as a HRC wiring harness electrical diagram available ?
Or is it exactly the same colours etc. as the standard with all the road things removed ? _________________ Poul

The only wiring diagrams I have are of the F3 harnesses.
As far as I'm aware though, the colours are all the same as stock on the SS/SP HRC harness. Easiest thing to do is compare the two plugs that go into the PGM-III on each harness, side-by-side.
The 2 SS/SP harnesses I have are boxed up in the attic at my Dad's somewhere, else I'd have had a look for you. _________________ Andy.

For colours I could have a look myself as i definitely have a HRC box on one which indicates HRC wiring harness and probably a normal one on the other.
For the wire "where to", it would be much easier to have a schematic though.
Now you are here Andy; haven't you or one of your advanced tinker friends ever put a mutimeter on the RC valve solenoids while the bike was on the dyno ? Or just running on the floor. _________________ Poul

Matt's your man for that really! He has a test rig set up on the bench to measure all things ignition.
As far as I am aware, the RC Valve movement and position is governed by the TPS and RPM on the PGMIII. The feed is only +/-12V, and the position of the valve depends on the pre-set perameters programmed into the PGM. A particular throttle position at a particular RPM will have a corresponding RC Valve open/closed position. The sweep of the servo will be down to the transition between one set of perameters to the next.
I could be making it all up though! _________________ Andy.

I'm actually just looking for the voltage levels as I want to make a module to place between the PGM and the valve solenoid. Its too silly, that so many people burn that expensive PGM and nobodys done anything about it.
There aren't going to be more of the PGMs around in the future either.
I guess the voltage is +-12V where the current is sent through the motor in either direction. But being transistor outputs, it could be less f.ex. +-8Volt or being Honda, they might send different voltages out, to be able to control the speed of the valve motor, which is normal in regulation circuits with fine tuning.
I'll just wait for Matt to get out of the kitchen (wasn't that where he kept his bikes ) _________________ Poul

It could be, but the motor could also effectively "step", albeit in tiny increments. Like I say, I don't know, and it's my best guess.
The simple way to do it is with a shift light. Set the shift light to say 8000rpm, and instead of a light coming on, actuate the servo instead. You'd need to figure out how to stop the servo at the required full open/full closed positions to stop it simply straining the motor against a physical object such as the port roof or taught cable, but it wouldn't be hard. _________________ Andy.

It's not the voltage levels burning out the PGM, it's the current draw when the motor strains agains carbon build up. Unlike an AC motor, a DC motor will draw huge currents when it cannot respond to the applied voltage. That's why they use them in trains.
Just fit a circuit breaker in line, and mount it somewhere you can see it.
Better still, just keep the power valve clear of carbon... _________________ MC21SP Plaything
