So, I am going riding Sat. with Tillerfizzer and haven't ridden in awhile. Put the bike on the battery tender overnight, next morning, starts right up. Go on our ride for breakfast, hang out for a bit and come home. Real quick, installed a GPI/TRE awhile ago and bike has been a little funny since then, takes forever to start when hot, one time not at all. On our way home, I notice that the speedo and tach needles are at zero, but mileage, temp and LED's for GPI are working. Pull in clutch and bike wants to die. Get to red light and have to rev engine entire time stopped. Take off, now everything is dead. A minute later, everything is back on, displays, needles, GPI lights, whatever. Now have a fault code of c41, fuel pump relay. Get home shut it off, put it on the stand, try to start, and all it does is crank. Kills the battery. Turn key off and it is still cranking until the battery is totally drained. Put multimeter on battery and it reads .300 mV. DEAD!. Go get a new battery, try to install this evening and as soon as I touch positive, it starts to crank. Key is out and kill switched is engaged. WTF! I have no idea what is wrong except that the GPI/TRE is the culprit. I will be removing it when I have time and will be putting it up for sale. Any suggestions as to what is wrong would be greatly appreciated. Also, before it died completely, when I would turn the key on, you could hear the fuel pump prime. Please help, anybody.
