- October 11, 2014, 21:14:00 PMThank you, I appreciate the response. I'm going to charge the battery tonight and hope it takes.
Again, thank you and as a side note....I'm not going to tell my brother he's right 'cause I'll never hear the end of it

The engine's charging system is adequate for maintaining the battery's charge under most, if not all situations, but you will burn out the rectifier, and possibly overheat the stator connections if you try to charge a dead battery by running the bike. If you keep it connected to the slave battery, while you're running it, it will be less detrimental to the charging system, but also take longer to charge...charge the battery, much safer in the long and short run....and no this is exactly the same as a car, so don't try to say that's ok, 'cause it isn't. DO NOT CHARGE AT OVER 1 Amp unless it's marked at a higher rate on the battery. Small batteries should be charged at 1/10 their ampere hour rating for as long as it takes.

- October 11, 2014, 16:06:01 PMStarted up the bike with a jump figuring it would charge going for a ride but got a mile from home and it literally looked like a Christmas tree on the console and then it died. I pushed it home (and needed oxygen!!!) and jumped it again. It would start and then die. Upon further investigation, I saw that all 3 lights on my Fi2000 stay on after starting and at idol. According to the documentation, I had a bad wire connection. I fixed the connection, jumped started it again and this time, only the green light stayed lit and the bike ran great, while jumped.
I did see that when I gave it some gas, the red and the yellow light would come on and then off when I let off the gas.

Is that normal behavior for the Cobra Fi2000? Just want to make sure.
And as far as charging the battery, my brother and I are arguing over that one. I thought that if I jump started it and then ran it that the bike would eventually charge it while my brother says the bike is dieing because it doesn't have the juice for the fuel injection and that the battery needs to be charged. That just doesn't make sense to me, I mean, why carry jumper cables if the bike is going to die after starting it? And isn't the alternator strong enough to be charging the battery (while riding) and have enough juice to supply fuel? Really curious as to who is right because I want to rub it in his face :-)
Thanks in advance to all responses.
