Hi y'all- So I've just developed a new problem. I've got no dash display (mph, odometer, temp, etc.) and my tachometer is dead also. The bikes staarts and runs fine, the tunrn signals and lights work, and the little LED's on the dash (such as kick stand, neutral indicator, etc.) DO work. The fuses are all good. Is there something else I could check, or do I assume it's my CDI/SPU? Is there any way to test that this is the problem, or do I simply replace it and see if things work?
Also, is there any place recommended to order one from, or is the dealer the best bet?
Thanks,
Michael

If I may quote Pink Floyd-"Is there anybody out there?" No suggestions or recommendations?

those displays probably share either power or ground ,could be SPU or something more technical but start with the simple (and cheap) stuff first, connectors first then power and ground supplies, a simple multimeter will be invaluable. A good jiggle does wonders sometimes,

keep us posted

Especially since you were playing around in the headlight area it`s quite possible you may have bumped the wiring to the dash. I`ll have a look at mine in case there is anything that looks easy to knock loose

Ok, you need a 2.5mm allen key and remove the dash cover, it slides forward after removing the two bolts. There are three connectors but the one you really need to check is on the right as you sit on the bike and it should have a rubber boot over it. Before you unplug it check for damage,loosness etc, then disconnect and inspect all pins are in place and clean ,maybe spray with some elec contact cleaner and reconnect and see what happens. If no joy someone else on here may be able give details of wiring schematics.

Thanks Mark- Take things apart and put them back together- that'll be the first thing I try, well within my capabilities! (Famous last words!)
best,

mrossk,
I just had the same issue with my 750.
After checking everything (Connections, fuses, metering all of the earth points on the bike) I had to bring it to a dealer.
Turns out the dash was defective, they luckily had one from an F4 parts bike kicking around.. They quoted me $1300 from MV, you can probably find one on the forum though.. Check the SPU part number and make sure it's the new one (see CAG's sticky at the top of the brutale forum page for more info).
If you have a friend near by with an MV see if you can borrow their dash to do a swap/test?
Good luck, and keep us posted
Nate

I took a chance and installed a new SPU and I'm happy to say it worked. Thanks to Star Twin for the really quick shipping and delivery (Less than week from Holland to New Mexico!). Not a cheap fix, buit it worked. As an FYI, one has to raise the tank some to be able to remove/replace the SPU- I supported the tank with a block of wood and the rest was straightfoward. As a few others have mentioned, it seems like the bike is a little smoother at parking lot speeds. Is that possible or am I imagining things?
Thanks for the input and advice!
Michael

yes I would really need is the color of the bands and hopefully by replacing that it will work. I will try to attach some pics for appropriate location. first picture shows the surface of resistor, second picture is the back. as you can tell that resistor must be special edition all black lol

Nope, Chuck the resistor looks like a charcoal all black. its the resistor between the caps on the picture above. all black. i pulled it out carefully with the help of the soldering iron but as soon as i placed it on the table it just fell apart. i just need someone to take a pic of their resistor and i will try that value with hope of bringing my "spu"? back to life. guys i appreciate all the help

Gototjoe may be the right guy to come to the rescue. He has had dashes apart and could probably tell what the original color was.
