I had a low battery on the 2003 winnebago adventurer, so I tried to start with the emergency start swith...I did not get any power..Where should I start the troubleshooting??Bud
Not sure where your relay is, but it is easily tested. It should have 2 large posts and 2 small. Based on your problem, one large post should have good voltage and one will be low. When you push the button, one small post should get power-the other is ground. While holding the button, the 2 large posts should start to equalize.
