Everything was running just fine until one morning I go to start it, the battery was dead. I get a jump and it was good all day. Until the about a week later. Same thing. And I keep it in a heated garage. Not sure if it’s the alternator ( highly doubt it ) but it might be just a bad battery because I checked all the fuses and it’s all good. But now, when I turn the starter, there’s no juice at all. The instruments gauges won’t even come on and the battery is good. Any ideas? ---

How do you know the battery is good? ---

> [@JohnnyutahRawls](#): > > ) but it might be just a bad battery Take the battery out and have it checked . Or if you can start it with a jump go have the battery and alternator checked . Eliminate the simple things first.
