M-unit to ignition system. Virago xv1100

PostAuthor: Grimstad » Sun May 05, 2019 1:28 pm

Hi everyone!

I have some questions about how to wire the ignition system on my Yamaha XV1100 Virago 1997 together with the Motorgadget M-unit blue.

I want to follow the Universal m-unit wiring diagram for carburated motorcycles from revival cycles: https://technicalarticles.revivalcycles ... ng-Diagram


What do I need to do to wire up the ignition system together with the M-Unit Blue on my bike?

Is my ignition black Box a CDI? If it is how do I wire it then?

Hope you can help me.

The Virago has a TCI NOT a CDI. Very, very different systems. Color codes for the Ignighter (TCI) wiring are shown on your wiring diagram. You need to ask the supplier of the M unit what needs to be wired to the ignition, most likely just the ignition switch so the unit only has power when the ignition is on.

Thank you for your answer :)

If someone have done the exact thing I'm going to do, i would be extremely happy to get the wire routes explained :)

The way I see it, is to connect the TCI to the m-unit, so the TCI got power +

Eliminate the "diode" and the "starter circuit cut off relay" i can't see I'm gonna need those?

But. How do I wire up the start relay? Should I swap it for a solenoid or can I use my existing starter relay.

Thank you for all help!

After studying the M unit wiring diagram and reading the instructions, with a TCI system the Brown wire that is on the OUT side of the key switch connect should connect to the Red/White wire that provides power to everything on the bike including the TCI and Ignition Coils. The IN side of the key switch connection should have power when the M unit is turned on. There is no reason that I can see to remove the Diode or the Start cutoff relay... If this isn't good enough, send Totally Red Virago (TRV) a PM or email as he is the sites wiring expert....

Thank you for the answer. The reason I thought I had to remove the Diode is because i thought the m-unit did the diodes job?
If i cannot remove the diode how do I connect everything then? The diode is connected to the engine start switch. The m-unit is also supposed to be connected to the start switch.. I get confused.

The Diode controls the following: Oil level switch; fuel pump; clutch switch; neutral switch; oil level warning lite; engine start switch; starter cut off relay; fuel sender; fuel warning light. Are you planning to connect all these to the M unit or eliminate them? The starter cut off relay converts the ground (earth) to the 12+ volts required to activate the solenoid. All the inputs to the M unit must be ground, no battery allowed. The M unit simply turns on the function by providing a positive voltage to the specific circuit involved. What made you decide to use the M unit? Like I said, PM Dan.

What makes it hard for me to understand is that the m-unit is connected to the starter button and the stop/kill switch.
The diode and cut off relay also needs connection to the start and stop of the bike.
Yeah I would really appriciate som help from Totally red virago.

I dont know why i chose the m-unit. I guess I thought it would be easier, but I dont think so now.

Aftermarket devices rarely work better or are easier than the stock setup the engineers designed and have proven to work on the model bike in question. Something "Universal" never is easier nor will it work better. The M unit is just a computerized switch to send signals to various components. IMHO the unit is totally unnecessary and is just something else to go wrong. Go to the Members tab and search for totallyredvirago, no spaces. You should be able to find his contact information there. I have sent him an email suggesting he contact you.

I just read that when using a M-unit: "Wires that connected to the key switch / fuse block / kill switch or battery + in the ignition system will now be connected to the m-unit ignition output"

Seems right?

For some reason, TRV is unable to log into the site. I copied your wiring diagram and the link to the M unit wiring diagram and sent them to him just now. I will post what he tells me as soon as I get it back from him.

Yeah thanks, I have read those. Still need help figuring out what to do with the wires higlighted in yellow on the Picture above.
Has Totally Red Virago looked at my problem?
