Electrical problems

Post by JoBoy68 »



Electrical problems are a bit past my understanding. First a question about the lights on the rear saddlebags are they supposed to be just blinkers or blinkers and running lights it looks like someone did some rewiring. I started it up for the new season and my right rear blinker is flashing between the two filaments one filament lights up and then the other that is the blinker ,on the dash the right blinker a light is always on I turn on the blinker and it flashes on and off. I pulled in the clutch to start the bike and nothing put it in neutral and it started. next my charging amps , I start the bike and it slowly goes up to 12.8 then down to 11.9 rode for like 4 hours and it continually read 11.9 stopped to get gas when I started the bike back up it slowly went up to 12.4 then back down to 11.9 and all the way home it went from 11.9 to 12 and back. 83 GL 1100 interstate any suggestions of thought will be appreciated

It appears you may have a charging issue. The stator plugs on these old bikes are subject to corrosion and heat and can cause the wires to burn. My plug was in terrible condition. I would start by inspecting the plug. You can also test the stator for faults. The rear wiring on my bike had numerous t taps, splices and connectors leaving possibilities for open circuits or shorts. You will have to inspect and test with a multimeter to find the trouble. I plan on replacing the main battery ground and power cables as well.

It appears that you may have multiple problems. Low charging voltage is one. The 3-wire plug noted above is located just left of the battery.
A 2-filament bulb indicates a turn signal, and a running light function. When the two filaments alternate blinking it is likely an open grounding. The current through the turn filament can't find ground directly, so it sort of finds ground back through the running filament (and vise versa). Check for corrosion in the socket, and verify the socket is grounded to the frame.
Start with that, and report back with any new or changed symptoms.

========================UPDATE=========================================First charging , the plug with the yellow stator wires by the battery melted and was replaced years ago . I held the wiring harness with those wires and it was hot , the metal inside the wire connectors was very hot , I cut it all out and soldered in some heavier wire 12 gauge. I started the bike up and the charging amps went up to 13.9 ran it for an hour Amps went down to 12.3 and the new wires never even got warm , my opinion they did not use heavy enough wiring and the plug by the battery is the weak point. Now my turn signals . They were originally just turn signals and they were rewired to be turn signals and running lights, I unplugged the running light wires and the blinker started working properly so I took out the extra wiring and put it all back to original. Last , pull in clutch hit the start button headlight goes off back on but no turning of the starter, Found an unplugged wire by the hi-low beam switch , now hold in clutch and bike starts , so it was a very good day
