spartikus Posted September 23, 2014 Share #1 Posted September 23, 2014 I have been on an epic journey the last 3 days playing with my new bike and posted a crap ton of details on another forum but hoping to get more sets of eyes here Alot of these details I have been typing over and over for several days so I'll try and just keep it to the facts at hand. Thanks in advance for any help or advice. The bike: - 1984 XVZ1200 - Hadn't been on the road in 4 years (or started) - Got it running in a few hours. Ran awesome and started no problem - Changed oil (twice, let it run for 29 mins and changed again) just to be safe The Issue: - After knocking a wire loose putting on the plastics the bike will no longer start. It turns over, all the accesories light up, headlights work, signal lights work, hazard lights work but no brake lights and wont start. - Putting the plastics on the bike (they came to me in several boxes) I bumped a black wire that a PO had obviously jury rigged into something near the front of the bike. The wire came loose in my hands before I could trace it to where it may have been attached up front. It lead down to the rear brake switch which is a three wire switch (should only be two wire I think) and a PO had basically butchered up the wires down there I think making the three wire switch work on a circuit designed for a 2 wire rear brake switch. - Before I knocked the wire loose the bike started and idled like a champ. All brake, hazard and turn signals worked perfectly. What I know: - The kill switch is not the problem tested many times with multimeter 9 ways from Sunday. - The Tip Over switch is not the problem. Tested an equal number of times. - Pulled the B/W plug from the TCI to bypass the interlocks perdiod (That stops them from interfering with the ignition yes?) - I have 12V to the coils when the ignition is on - I have no spark to the plugs cycling the engine with the starter - The bike started and ran great for the 30 minutes I had it running and it wasn't until the wire fell off in my hand that it wouldnt start and the brake lights didnt work. What I "think" I know: - The bike should have a 2 wire rear brake switch not a three (based on the fact that the three wire switches are for bikes with venture cruise. My bike has a cruise control but it is just a throttle lock installed by a PO) - A 2 wire front brake lever (which is what my bike has) shows a closed circuit in the free position and an open circuit when the lever is actuated. This is different from the 4 wire lever circuit. - A PO had jury rigged the yellow wire from the rear brake switch over to the Yellow wire going to the rear tail light - A PO had taken the brown wire lead from the rear brake switch and run it up to something at the front end of the bike. (this is the wire that fell into my hands and started this whole mess) - A PO had spliced the brown and Green/Yellow wire coming back to the rear brake swithc together (I think but I am not positive as the electrical tape job and wiring mess was impossible to see as I pulled it apart). He then put a lead from the Br and G/Y wire he spliced together and wired it into the Green lead from the rear brake switch. My querry(ies): - I HAVE BEEN MAKING MY EYES BLEED FOR THREE DAYS TRYING TO FIGURE THIS OUT HALP ME!!! - Whew ok now that THAT's over with As I stated the bike was running like a top until that wire came loose. Sure it could be coincidence but I sure would like to get this figured out. - Does anyone know what the hell he might have plugged that brown wire lead from the rear brake switch to at the front of the bike? I'm guessing the computer monitor but man not interested in risking the CPU with a guess. Any thoughts, suggestions or anything gratefully appreciated.. Even if it's just you telling me to go have a beer Thanks in advance folks, Mark Link to comment Share on other sites More sharing options...
