Green Machine Posted May 19, 2012 Share Posted May 19, 2012 I just had my 2000 R1100rt abs into the dealership. They installed a set of Denali D2 lights. I had several problems with the quality of the work. The tech left a plug off and forgot to attach a hose clamp to the fuel line. He also left a large bolt out of the fairing when re-attaching it. All issues were addressed by the dealership. I took the bike home and all was well. Two days later, I started the bike and one of the lights was not working and the windshield was not working. The dealer stated the light was defective and the motor had gone out on the windshield. They stated it was totally unrelated to the work the tech had performed. I was wondering if the work they performed could have been related to the work that the tech performed while installing the lights. Link to comment
OoPEZoO Posted May 19, 2012 Share Posted May 19, 2012 First off, welcome to the board Hard to say, but I can't imagine anything having to do with aux lighting that would damage the windshield motor. I suppose they could have knocked a wire loose or blown a fuse, but actually damaging the motor would be pretty hard to do. How many miles on the bike? Link to comment
Green Machine Posted May 19, 2012 Author Share Posted May 19, 2012 51,000 miles. I was asking because it seemed to coincide with the repairs done by the dealer Link to comment
Quinn Posted May 19, 2012 Share Posted May 19, 2012 Think I'd be looking at other options for future service. Not saying they're not right, but I'd be losing my trust level. Poking around in old wiring harnesses would make me suspect corroded connectors and shorted wires before motors and bad light assemblies. ------ Link to comment

Car 54 Posted May 19, 2012 Share Posted May 19, 2012 What Peter Parts said. (What was that)? Link to comment
Green Machine Posted May 19, 2012 Author Share Posted May 19, 2012 Thanks for the info. The closest BMW dealer is in St Louis Missouri which is about 4hrs away from where I live. Link to comment
KDeline Posted May 20, 2012 Share Posted May 20, 2012 I don't believe in coincidences. Link to comment
MT Wallet Posted May 21, 2012 Share Posted May 21, 2012 Can you power the windsheild motor directly with a battery? If it works obviously the motor is good. Quinn may have suggested the places to start trouble shooting. Connectors and wires. Link to comment
4wheeldog Posted May 21, 2012 Share Posted May 21, 2012 Nor do I. Since a light quit, I wonder if they possibly spliced into the wrong wire, and had one side of the power to the windshield going through the filament. Stranger things have happened. Link to comment
Galactic Greyhound Posted May 22, 2012 Share Posted May 22, 2012 When the light went it may have taken out a windscreen fuse depending on how the tech wired in the Denali D2 lights. The windscreen circuit uses two fuses; Fuse#3 15A is for the windshield motor and this fuse also supplies the power outlets (handy for extra lights???). Fuse#4 7.5A is for the windshield UP and DOWN relay coils and this fuse also supplies the horn. You need to check BOTH fuses #3 & #4 as the windshield will not work if any of these fuses are blown. The 12v power to the windscreen motor is reversed by the UP/DOWN relays depending on whether the motor is required to Raise or Lower the screen i.e the motor is reversible - you can connect 12v to it and it will turn one way, reverse the voltage and it will turn the other way.

Green Machine Posted May 25, 2012 Author Share Posted May 25, 2012 After checking out the bike, I found the heated grips are not working now. Link to comment
biometrics Posted May 25, 2012 Share Posted May 25, 2012 FUSES... Check all FUSES with an ohmmeter... replace any that are blown and THEN start troubleshooting... Link to comment
dirtrider Posted May 25, 2012 Share Posted May 25, 2012 After checking out the bike, I found the heated grips are not working now. Afternoon Green Machine Really no telling what you have there as you seem to have somewhat unrelated failures. The windshield motor is powered through fuse 3 & fuse 4, the heated grips are powered through fuse 7. The only related interface between the heated grips & power windshield is the ground path back to the battery or main power from the ignition switch. Problem is, that ground is also for the headlights so you would think that if that ground was corrupt you wouldn't have headlights either. If the problem is with power out of the ignition switch then more than the windshield & heated grips should be non operational. I guess to start looking for the problem--- verify fuse 3, fuse, 4, & fuse 7 are in place & not failed. Then maybe make sure the small wires are hooked securely to the battery (-) post. Otherwise you will probably need get more involved into the problem & remove the plastic & possibly gas tank & chase all the failed circuits to their switches & verify 12v power & intact grounding as well as proper wire termination & connection at the failed accessory.

Green Machine Posted May 26, 2012 Author Share Posted May 26, 2012 I checked and the #7 fuse was blown. I replaced it and started the bike. The heated grips worked but the front right aux light(the same as the first occurence) is not working again. The first time I took it into the dealership they stated it was a defective light. The manufacturer replaced it under warranty. Now it appears that the light was not defective and it has to do with how it was installed by the dealer. Link to comment
dirtrider Posted May 26, 2012 Share Posted May 26, 2012 Morning Green Machine Seeing as we don't know how the dealer wired it there is no simple way we can tell you how to repair it. Basically the light needs 12v power & a good clean return to battery ground to operate. To troubleshoot yourself you can turn the aux lights on then use a voltmeter or 12v test light to verify 12v power TO the light assembly & verify a proper ground at the light. If you have 12v power TO the light & a good ground then the light itself is defective. If you are missing power or a good ground then you will have to go in farther to find out why. Link to comment
