my 08 rcsb is acting weird on start up. first i thougt it was related to the starter but now im not sure. sometimes when i turn the key i get absoluting nothing, now lights on the dash no sound from the starter, no atempt to start at all. then other times it just starts right up. i'm at a loss as to why im getting no power sometimes, any ideas?

 

Battery connections clean & tight? Check those and follow them to the alt, etc and make sure all is tight

 

thanks, ill start at the cables 1st thing in the morning.
