The terminals were dirty so started taking each one apart to clean and reassemble. About the fifth terminal in, the cable just fell off from the battery post. The cable lug was eaten through so it was just touching the ring part on the battery post. Finished cleaning the rest, replaced the terminal lug and reassembled. Turned on all power and now ALL is working as should! I guess it does pay to check the easy and obvious stuff first. Thanks for your help.Problem with 12 volt side of electricalWe are currently at a park in Arizona and started having 12 volt electrical problems. All is fine until we turn on a light (bedroom, kitchen, or even open fridge door). The light will come on for a split second and turn off. The Intellitec EMS panel will either dim really low or turn off. When the panel comes back on, it will have random flashing lights. All power (120 and 12 volt) will turn off and come back on. This only happens when using 12 volt items. 120 volt items are fine (a/c, TV's, 120v lighting). We are hooked up to 30 amp service and it is fine. Everything is working OK except the 12 volts. No breakers trip, no fuses blown. House and coach batteries are charged. We have the following: 2008 Fleetwood Expedition diesel 4- 6 volt golf cart batteries for the house Intellitec Smart EMS model 900 Magnum Energy Inverter/Charger model MS2000 Progressive Industries EMS model HW50C Battery Control Center by RV Custom Products Kill-A-Watt (it says all electrical is fine) Battery charger is on float at 13.2 I have looked around to find a converter but can't find one. Not sure if I have a stand-alone one. Any ideas on where to start troubleshooting?Re: What do you tow behind your Motorhome?This is how we roll: 2009 Ford Flex.
