2012 DL650 Starter Issue
So I have been having a starting problem recently. Let me give you some background on what is going on. I bought my bike used earlier this year kept in great condition and only had 4K miles. Since then I have bulked up the bike for going offroad and have been riding a lot in the sand/swaps of south Florida it has been a blast. About a month ago I decided to wire up a usb charger and voltmeter on my dash. I did this lazily dragging wires along left side of frame without taking off tank. Got it wired up and then was just pulling the fuze on the small box I wired it up with to until I put in a relay. A couple of times I forgot to pull the fuze but the battery didn't drain too far. One time the after sitting for 4 days with volt meter on batter drained to like 12.4-.5 and this is where the problem starts. Tried to start bike all I hear is clicking from starter relay. Pull battery and charge overnight. Next day fully charged battery but still only clicking. I push start and bike fires right up. After this problem is intermittent and I never reattach my wiring to isolate that variable. So on and off the bike will either start or not and click. I have since replaced the battery (was stock so I figured was about time anyways) but the clicking happens even with more than 12.6V, voltage measured at starter relay mirrors that of battery. I do get a dimming of my headlights with the starter button press. I have not found a pattern to the issue it will happen on cold bike or when I have just stopped for 5 mins / accidentally shifted to first with stand down. Started will also variably spin or not and click once the motor is running... I think I may have heard a pop that was louder than the clicking on attempting to start once but have never recreated with seat off. Rolling forward/back in gear does not fix problem once the starter is not functioning.
Based on all this I thought maybe a bad ground? Or possibly a loose connection from when I dragged wires? I really don't think it would be my starter motor as my bike has only 6K miles. I wanted to check the engine ground connection to the motor but I do not have my manual and dont know where that is or how to access it. What do ya'll think?
