mkenway Report post Posted August 24, 2012 I own a 2008 Itasca Suncruiser and have a number of issues with my 12v electrical. I'm not sure if they are all related or not. First the coach heater that runs off the engine while driving has no power to the switch, but power at the fuse box. Second, the house batteries don't charge while driving... no 12 v power going to the battery mode solenoid. Third, no power going to the 6 amp breaker ( under the entry step) that controls the step when the engine is turned on and the 5 amp step alarm fuse (under the drivers side) keeps blowing. If anyone knows what might be causing all these issues, I would be very thankful. It's puzzled me for over 5 months. Thanks, M. Kenway Share this post Link to post Share on other sites
hermanmullins Report post Posted August 24, 2012 M Kenway, Your coach has one and maybe more 12 volt continuous solenoids. They look just like the old starter solenoid on Fords, You have two large studs on each side and two small stud on the front between the two large studs. The large stud on the left should have 12+ volts and you should have 12 + volts on the right stud also. If not turn your key on and check the right stud again. if you still do not have 12 volts you have a bad solenoid. You need to check all of your solenoids. If you have a bad solenoid be sure that when you purchase a new one that it is a 12 Volt Continuous Solenoid, Herman Share this post Link to post Share on other sites
mkenway Report post Posted September 4, 2012 Thanks for the suggestions. I have determined that the reason for the 5 amp fuse blowing is a fault with the step controller. After removing the wire that connects the engine override for the step, the fuse remains good and all the other problems are resolved. Share this post Link to post Share on other sites
