I am having an issue with starting the coach with the starter batteries. I have installed new batteries (two 8D2, 1700 CCA each). the starter will engage and the engine will turn over a couple of times and that's it. I have removed and cleaned all the cables, and have checked the ground all the way from the negative post (fuse on negative post is good) to the block and to the starter with one to two ohms max. Batteries are charged and alternator is working fine. It will start when I use the merge switch. My question is how many amps will the starter draw on average, I know if the engine is really cold it could draw more current. Right now in 50 degree weather, the starter is pulling about 551 amps, not sure if this is high and I could have a starter going bad.
