WTF high idle/dead battery?
so the other day I noticed my truck seemed to be idling higher than normal (around 770-800 rpm's) sometimes itll go back to normal. this morning I noticed it seemed to start just a little slower than normal. drove it all day no problems. tonight I changed the tune to the spartan 210 tow tune, drove around to the boat and hooked up to it for the early am. shut truck off 2mins later went to start it up it up to move it just a little and DEAD BATTERY. WTF!!!!!!!!!!, turned it over again and barely got it to start. un hooked it from the boat and now have it on charge. what gives? OBC said charging system ok
