Finally got her running, no no gauges..

[guidoxpress]

got the 06 900 i am building running today, just need to button up a few things.

1. installed 2 trail tech fog lights, work great.

2. no gauges however...

im working on searching for common issues, but in the meantime would like to get some other inputs.

--i have switched the chassis relay with 3 other...no gauges.

--i have powered up the gauges using the red/white and brown wires...gauges do work.

--disconnected everything from the handlebars (warmers/kill switch) so i have elminated a pinched wire on the bars grouding out...no gauges

--i have NOT checked the power on the chassis relay as per compfusions statement below..

The red (terminal 30)at the chassis relay is the regulated supply. It is switched through the relay to the red/white(term 87) to power the chassis equipment.
Check from the red/white to brown for voltage to see if the chassis relay is working properly. If incorrect or no voltage check from the red to brown (ground) to determine the regulator output. Regulated supply is also present at terminal 85 (red) to provide coil voltage to close the relay and is ground switched through the ECU.
BTW the relay is a common 4/5 pin found used to switch on driving lights and such

so while i am searching for common issues, anyone have any suggestions?

What happens if you ground white/blue at relay to chassis ground? (use jumper wire from terminal to chassis w/engine running)

actually i am just going to do that now...came across this post from you a while back..

I just solved that exact issue literally minutes ago out in the shop. I have 05 900 switchback, rebuilt top-end, started up- ran fine, but no lights, mfd. After checking chassis relay, red power wires to the relay and white/black ground wire from relay going to ecu (tested fine) , out of curiosity I grounded w/b relay ground to chassis ground with jumper wire and lights/guages came on! Luckily dealer had extra ecu I was able to swap-out for diagnostic purposes and then go from there kind of thing, it works/runs great so in this case, bad ecu for me! Hopefully yours will not be such an expensive fix! Definately look to your chassis relay first and go from there, good luck!

be back in a few mins with update

jumped the white/blue wire to ground while engine is running, no change...

i have headlights, but no gauges...should the lights be out as well if the ecu driver is bad?

 

[Z-Man]

Have you tried testing the wires that power the MFD for continuity with an Ohm meter to see if you might have a broken wire? If you have power to the lights, you should have power to the MFD. Do your handwarmers work?

unplugged my warmers once i noticed the gauges didnt work.

i put 12VDC to the red/white and grounded the brown wire on the plug on the harness..this will apply 12vdc to the gauges and other areas to check for power...this is what the dealer uses.

once i applied the 12v. the gauges worked fine, i have another set of gauges that i tried as well and they are fine. have not tested the gauge harness yet. but all pins are intact and no signs of rust bad connection.

going through wiring diagrahm now to test...something? lol.

 

[guidoxpress]

i can swap the ECU easily, but my spare ECU is an 06 rmk 700 flash..so i will have to get it reflashed by the dealer to a 900, and for the SLP package.

trying not to get frustrasted. ha!

 

[guidoxpress]

i also have a spare hood wiring harness, swaped it out real fast to see if there was a bad wire in the old hood harness, no gauges still...

i have a few extra chassis wiring harness also, but what a PINA to swap that out "real fast", lol.

Just going to have to track it down from mfd back to chassis connection, which I'm sure you're onto. Also confirm connections @ regulator are good. Keep us posted brotha!

 

[guidoxpress]

will do SW.

so do you think the ECU would be bad if the lights still work?

 

[sw]

No, but I have been slapped upside the head before! I've a hunch it's something simple, but difficult to see offhand kinda thing. Went for ride today and the eyes are a little shot to go over schematics, may have to do with 160hp connected to that little flipper thing on bars! Will look after a bit.

FIXED IT!!

so long story short...the wire i was using to add external 12VDC to pwr the gauges...well that was the actual wire that powers the gauges only..it was cut and taped to the harness by the steering hoop.

the guy that built the sled originally had removed teh stock gauges, and ran only egts. (dumb idea) and he must have cut the wire for the gauges and used them to pwr the EGTS...i sold the gauges a while back, and that wire was just taped shut in the harness...so i am not sure if i did it or if it was like that...

i have never ran this sled since i got it..started tear down and thats all.

so i connected the cut red/white wire to the original harness, mokced the tank, exhuast and whatnot on real fast for a simple start up.

and they work, no codes, no issues...

so now i need to pull it all apart again, put all the wire loom back on, yadda yadda, assemble for good, bleed coolant, touch up a few things, and should be good to go..

also need to confirm the warmers, kill switch work after i bleed the coolant, i dont want a cold sieze, lol.

so thanks for all the inputs, we had a scare but some simple checks and good to go...

ill update my build thread hopefully tomarrow...should be all good to go by this weekend...BUT im still waiting on my clutch from indydan.

 

[sw]

Can we move on now?! Awesome tracking!

 

[sks rider]

Guido,

Did you ever ask indydan about the clutch bolt torque?
And good job on getting the guages working.

 

[Danbot]

Looking down at gauges = not looking at the trees (or truck cab)
sorry Sean, I had to

yes sir..we can move on now, lol.

Guido,

thanks...and no i have not talked to dan..he is suppose to call me when the clutches are done, and when the 975 he is working on for me is done...so was gonnaget clarification on the standard crank/clutch torque spec, and the TM crank/clutrch bolt spec

sorry Sean, I had to

dan....i have a 975, and you dont, LOL

 

[Danbot]

dan....i have a 975, and you dont, LOL

Sean, my sled is complete and will be busting pow next weekend.... will yours?

 

[rmk2112]

Sean, my sled is complete and will be busting pow next weekend.... will yours?

OUCH, thats gonna leave a mark!!

"busting" is right

OUCH, thats gonna leave a mark!!

"on your face"...im out!
