McCruise ordered

[vanguard138]

Wow, just received notification it will be delivered tomorrow. That was fast.

 

[Joesmoe]

I was amazed how quickly mine arrived, complete with all kinds of esoteric markings from both Australian and US customs. Modern commerce flies.

 

[vanguard138]

Yes, ordered it Monday. Delivery faster than I will install.

Needs to get WARMER!!!

 

[vanguard138]

It has arrived, not sure if I want to open it

Now for a couple warmer days.

Just take your time, and the adage from carpentry is good here too: measure twice, fit once.
.

Wait, I cut it twice and it's still too short

Yes, ordered it Monday. Delivery faster than I will install.

you wouldnt happen to be installing a @DEcosse keyless system would you? If so you will need to install a diode in the blue wire coming from the MCCruise unit to the clutch switch. Ken and I spent a few minutes on tue phone yesterday figuring that out. Ken is a great guy that helped me out tremendously

Ruh Roh . . . WHAT diode ???

I have the @DEcosse kit too, with the McCruise already on there.

Any more details would be greatly appreciated.

Thank you.

I installed both at the same time and the keyless unit was picking up a ground thriugh the MCCruise unit via the clutch wire So we installed a diode on the blue wire such that the ground from the keyless unit couldnt backfeed the the cruise box. Im sure Ken can explain it way better, but it was a simple matter. I just cut the blue wire, soldered in the diode, heat shrinked it and voila...done and working as advertised. Before the diode i didnt have to pull in the clutch to get power to the system...as soon as I flipped the kill switch to run everything was hot. Ken figured out why and came up with the fix

 

[Joesmoe]

Might you specify the diode part number and the polarity as installed in the circuit, please ?

So we installed a diode on the blue wire such that the ground from the keyless unit couldnt backfeed the the cruise box.

Technically, it's actually the other way round - the MC Cruise is providing the 'ground' (not truly ground, just low enough impedance relative to my pull-up resistor) to trigger my Key-less. The diode blocks the current flow from my box to the MC Cruise, but still allows current flow from the MC Cruise to ground via the switch when it is closed.

Might you specify the diode part number and the polarity as installed in the circuit, please ?

Sorry - I had not realized you had the MC Cruise - as R3Tex says I realized the Ignition-on was setting immediately and had recalled when looking at the MC Cruise set-up that it too used the Clutch Switch as a Trigger;
there must be a low-impedance path inside the MC Cruise that takes the voltage to my KeyLess system low enough to trigger it without closing the actual clutch switch to ground

It's a pretty simple fix - you just have to install a diode on the blue wire to the MC Cruise

You can pick up a diode at Radio Shack
Just about any rectifier diode will do (1N4001, 1N4003 etc)
This is the one I typically use as general purpose


It has to go on the Blue Signal line between the actual clutch signal wire and the MC Cruise.
The only thing to be careful of is to ensure that the Cathode (end with the stripe) goes to the Orange/Black end and the Anode (non-stripe end) goes towards the MC Cruise.

You might ask "why do I have to modify the MC Cruise connection, rather than your Key-Less connection?" Well, the MC Cruise is the component that is providing the low impedance path and that is what needs to be blocked; putting the diode on the Key-Less would not work, it would not allow the path to the real ground via the switch, either (and if forward-biased it would not block the current path to the MC Cruise).

vanguard138 - a diode & instruction will be in your kit.
