Bike displays the following: when using directionals or brakes, volt meter spikes down and tape cassette/instrument backlighting dims. Also after starting engine and then shutting off heard starter bendix spin down. In addition, hear stactic/feedback through rear speakers, when using directs/brakes.
So far have:
checked all light grounds, added two additional grounds (one from frame to starter mount bolt and one from front of frame up to grounding block under instrument cluster). Changed out starter relay. Also have disconnected starter wiring from starter (connected batt pos cable and lead that share starter post together, but removed from starter post, to remove starter from problem. Still have same initial sympthoms. Any ideas/direction> Thanks
