Question about 1984 Honda VF 1100 C
1983 VF 1100 Honda Magna The idiot light for the tail light is on, no tail light nor license plate light. The 15 amp fuse blows immediately when the ignition key is turned to on position.
I have not been able to find any direct short to ground, all wiring is in good condition. I disconnected a 3 pole connector located behing the fuse box...the one that has a W/black wire into it and connects to a small black box ....according to the wiring diagram I believe it has to do with the auto off for the turn signals. The fuse does not blow and the tail and license light both work when the 3 wire connector is disconnected. I'm thinking the problem is in the black box or in the proximity sensor that senses the position of the steering forks to turn off the turn signal. If this is true, how can I determine which is causing the problem....the black box or the proximity sensor?
Hi, Sherman884 nice novella before diagnosing your blown fuse issue check the bottom of your seat if it's metal and comes in close proximity to the positive battery post you need to take the necessary steps to ensure there is no contact (electrical tape, thick rubber insulation, hammer a dent in the seat bottom etc.) also you are going to need a wiring from your service manual a test light, an ohmmeter and plenty of extra fuses. If you turn on your ignition switch and immediately blow a fuse you have a hard/dead short and is usually easy to find. With a test light connected to the hot side of the blown fuse holder start stabbing the wire/s that leads away from the fuse holder and towards the ignition switch, you test light will illuminate validating the short. When the test light fails to illuminate you have passed the short and need to back up until the test light illuminates, then look in the immediate area for the short.
If you driving down the road for 30 minutes or 15 miles and blow a fuse you have soft/flying short and may take some time and patience to find.
If the main fuse/circuit breaker constantly blows/trips while riding you probably have a faulty battery terminal connection. Check battery terminals for damage or corrosion, check battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter if necessary. Any other fuses that constantly keep blowing while riding are usually caused by a loose or corroded ground wire in the circuit, which means you have to check, inspect, test each and everyone with and ohm meter set on a low ohm scale 100 ohms or less . Simply touch one lead to the ground source and the other lead to the battery negative terminal, a reading of zero indicates a clean solid ground. Any number reading or infinity indicates a poor ground and needs to be repaired. Poor or weak grounds require excessive additional amperage to complete the circuit which in turn blows the small amperage fuse.

there is an idle screw on the base carb witch is probally on the right side of the bike and the idle should be at just under1000rpm

Well, when you take off the fork make sure you empty it first before anything else then make sure that the fork pressure spring is released before changing the seals. The fork oil amount should be no more than 200 cc or no less than 190 cc
